MC9S12DT128B Device User Guide — V01.07  
Section 1 Introduction  
1.1 Overview  
The MC9S12DT128B microcontroller unit (MCU) is a 16-bit device composed of standard on-chip  
peripherals including a 16-bit central processing unit (HCS12 CPU), 128K bytes of Flash EEPROM, 8K  
bytes of RAM, 2K bytes of EEPROM, two asynchronous serial communications interfaces (SCI), two  
serial peripheral interfaces (SPI), an 8-channel IC/OC enhanced capture timer, two 8-channel, 10-bit  
analog-to-digital converters (ADC), an 8-channel pulse-width modulator (PWM), a digital Byte Data Link  
Controller (BDLC), 29 discrete digital I/O channels (Port A, Port B, Port K and Port E), 20 discrete digital  
I/O lines with interrupt and wakeup capability, three CAN 2.0 A, B software compatible modules  
(MSCAN12), a Byteflight module and an Inter-IC Bus. The MC9S12DT128B has full 16-bit data paths  
throughout. However, the external bus can operate in an 8-bit narrow mode so single 8-bit wide memory  
can be interfaced for lower cost systems. The inclusion of a PLL circuit allows power consumption and  
performance to be adjusted to suit operational requirements.

1.6 Part ID Assignments  
The part ID is located in two 8-bit registers PARTIDH and PARTIDL (addresses $001A and $001B after  
reset). The read-only value is a unique part ID for each revision of the chip. Table 1-3 shows the assigned  
part ID number.

Bit 15-12: Major family identifier  
Bit 11-8: Minor family identifier  
Bit 7-4: Major mask set revision number including FAB transfers  
Bit 3-0: Minor - non full - mask set revision  
The device memory sizes are located in two 8-bit registers MEMSIZ0 and MEMSIZ1 (addresses $001C  
and $001D after reset). Table 1-4 shows the read-only values of these registers. Refer to section Module  
Mapping and Control (MMC) of HCS12 Core User Guide for further details.

Section 2 Signal Description  
This section describes signals that connect off-chip. It includes a pinout diagram, a table of signal  
properties, and detailed discussion of signals. It is built from the signal description sections of the Block  
User Guides of the individual IP blocks on the device.  
2.1 Device Pinout  
The MC9S12DT128B and its derivatives are available in a 112-pin low profile quad flat pack (LQFP) and  
in a 80-pin quad flat pack (QFP). Most pins perform two or more functions, as described in the Signal  
Descriptions.Figure 2-1 and Figure 2-2 show the pin assignments for different packages.

from the EXTAL input frequency. XTAL is the crystal output.  
2.3.2 RESET — External Reset Pin  
An active low bidirectional control signal, it acts as an input to initialize the MCU to a known start-up  
state, and an output when an internal MCU function causes a reset.  
2.3.3 TEST — Test Pin  
This input only pin is reserved for test.  
NOTE: The TEST pin must be tied to VSS in all applications.  
2.3.4 XFC — PLL Loop Filter Pin  
PLL loop filter. Please ask your Motorola representative for the interactive application note to compute  
PLL loop filter elements. Any current leakage on this pin must be avoided.

The BKGD/TAGHI/MODC pin is used as a pseudo-open-drain pin for the background debug  
communication. In MCU expanded modes of operation when instruction tagging is on, an input low on  
this pin during the falling edge of E-clock tags the high half of the instruction word being read into the  
instruction queue. It is used as a MCU operating mode select pin during reset. The state of this pin is  
latched to the MODC bit at the rising edge of RESET. This pin has a permanently enabled pull-up device.

signal, when enabled, is used to indicate that the current bus cycle is an unused or “free” cycle. This signal  
will assert when the CPU is not using the bus.  
The XCLKS is an input signal which controls whether a crystal in combination with the internal Colpitts  
(low power) oscillator is used or whether Pierce oscillator/external clock circuitry is used. The state of this  
pin is latched at the rising edge of RESET. If the input is a logic low the EXTAL pin is configured for an  
external clock drive. If input is a logic high an oscillator circuit is configured on EXTAL and XTAL. Since  
this pin is an input with a pull-up device during reset, if the pin is left floating, the default configuration is  
an oscillator circuit on EXTAL and XTAL.

External power and ground for I/O drivers. Because fast signal transitions place high, short-duration  
current demands on the power supply, use bypass capacitors with high-frequency characteristics and place  
them as close to the MCU as possible. Bypass requirements depend on how heavily the MCU pins are  
loaded.  
2.4.2 VDDR, VSSR — Power & Ground Pins for I/O Drivers & for Internal

External power and ground for I/O drivers and input to the internal voltage regulator. Because fast signal  
transitions place high, short-duration current demands on the power supply, use bypass capacitors with  
high-frequency characteristics and place them as close to the MCU as possible. Bypass requirements  
depend on how heavily the MCU pins are loaded.  
2.4.3 VDD1, VDD2, VSS1, VSS2 — Core Power Pins  
Power is supplied to the MCU through VDD and VSS. Because fast signal transitions place high,  
short-duration current demands on the power supply, use bypass capacitors with high-frequency  
characteristics and place them as close to the MCU as possible. This 2.5V supply is derived from the  
internal voltage regulator. There is no static load on those pins allowed. The internal voltage regulator is  
turned off, if VREGEN is tied to ground.  
NOTE: No load allowed except for bypass capacitors.

Section 4 Modes of Operation  
4.1 Overview  
Eight possible modes determine the operating configuration of the MC9S12DT128B. Each mode has an  
associated default memory map and external bus configuration controlled by a further pin.  
Three low power modes exist for the device.  
4.2 Chip Configuration Summary  
The operating mode out of reset is determined by the states of the MODC, MODB, and MODA pins during  
reset (Table 4-1). The MODC, MODB, and MODA bits in the MODE register show the current operating  
mode and provide limited mode switching during operation. The states of the MODC, MODB, and MODA  
pins are latched into these bits on the rising edge of the reset signal. The ROMCTL signal allows the setting  
of the ROMON bit in the MISC register thus controlling whether the internal Flash is visible in the  
memory map. ROMON = 1 mean the Flash is visible in the memory map. The state of the ROMCTL pin  
is latched into the ROMON bit in the MISC register on the rising edge of the reset signal.

4.3 Security  
The device will make available a security feature preventing the unauthorized read and write of the  
memory contents. This feature allows:  
Protection of the contents of FLASH,  
Protection of the contents of EEPROM,  
Operation in single-chip mode, No BDM possible  
Operation from external memory with internal FLASH and EEPROM disabled.  
The user must be reminded that part of the security must lie with the user’s code. An extreme example  
would be user’s code that dumps the contents of the internal program. This code would defeat the purpose  
of security. At the same time the user may also wish to put a back door in the user’s program. An example  
of this is the user downloads a key through the SCI which allows access to a programming routine that  
updates parameters stored in EEPROM.  
4.3.1 Securing the Microcontroller  
Once the user has programmed the FLASH and EEPROM (if desired), the part can be secured by  
programming the security bits located in the FLASH module. These non-volatile bits will keep the part  
secured through resetting the part and through powering down the part.  
The security byte resides in a portion of the Flash array.  
Check the Flash Block User Guide for more details on the security configuration.  
4.3.2 Operation of the Secured Microcontroller  
4.3.2.1 Normal Single Chip Mode  
This will be the most common usage of the secured part. Everything will appear the same as if the part was  
not secured with the exception of BDM operation. The BDM operation will be blocked.  
4.3.2.2 Executing from External Memory  
The user may wish to execute from external space with a secured microcontroller. This is accomplished  
by resetting directly into expanded mode. The internal FLASH and EEPROM will be disabled. BDM  
operations will be blocked.

MC9S12DT128B Device User Guide — V01.07  
4.3.3 Unsecuring the Microcontroller  
In order to unsecure the microcontroller, the internal FLASH and EEPROM must be erased. This can be  
done through an external program in expanded mode.  
Once the user has erased the FLASH and EEPROM, the part can be reset into special single chip mode.  
This invokes a program that verifies the erasure of the internal FLASH and EEPROM. Once this program  
completes, the user can erase and program the FLASH security bits to the unsecured state. This is generally  
done through the BDM, but the user could also change to expanded mode (by writing the mode bits  
through the BDM) and jumping to an external program (again through BDM commands). Note that if the  
part goes through a reset before the security bits are reprogrammed to the unsecure state, the part will be  
secured again.  
4.4 Low Power Modes  
The microcontroller features three main low power modes. Consult the respective Block User Guide for  
information on the module behavior in Stop, Pseudo Stop, and Wait Mode. An important source of  
information about the clock system is the Clock and Reset Generator User Guide (CRG).  
4.4.1 Stop  
Executing the CPU STOP instruction stops all clocks and the oscillator thus putting the chip in fully static  
mode. Wake up from this mode can be done via reset or external interrupts.  
4.4.2 Pseudo Stop  
This mode is entered by executing the CPU STOP instruction. In this mode the oscillator is still running  
and the Real Time Interrupt (RTI) or Watchdog (COP) sub module can stay active. Other peripherals are  
turned off. This mode consumes more current than the full STOP mode, but the wake up time from this  
mode is significantly shorter.  
4.4.3 Wait  
This mode is entered by executing the CPU WAI instruction. In this mode the CPU will not execute  
instructions. The internal CPU signals (address and databus) will be fully static. All peripherals stay active.  
For further power consumption the peripherals can individually turn off their local clocks.  
4.4.4 Run  
Although this is not a low power mode, unused peripheral modules should not be enabled in order to save  
power.

The PCB must be carefully laid out to ensure proper operation of the voltage regulator as well as of the  
MCU itself. The following rules must be observed:  
Every supply pair must be decoupled by a ceramic capacitor connected as near as possible to the  
corresponding pins (C1 – C6).  
Central point of the ground star should be the VSSR pin.  
Use low ohmic low inductance connections between VSS1, VSS2 and VSSR.  
VSSPLL must be directly connected to VSSR.  
Keep traces of VSSPLL, EXTAL and XTAL as short as possible and occupied board area for C7,  
C8, C11 and Q1 as small as possible.  
Do not place other signals or supplies underneath area occupied by C7, C8, C10 and Q1 and the  
connection area to the MCU.  
Central power input should be fed in at the VDDA/VSSA pins.

Appendix A Electrical Characteristics  
A.1 General  
This introduction is intended to give an overview on several common topics like power supply, current  
injection etc.  
A.1.1 Parameter Classification  
The electrical parameters shown in this supplement are guaranteed by various methods. To give the  
customer a better understanding the following classification is used and the parameters are tagged  
accordingly in the tables where appropriate.  
P:  
Those parameters are guaranteed during production testing on each individual device.  
C:  
Those parameters are achieved by the design characterization by measuring a statistically relevant  
sample size across process variations. They are regularly verified by production monitors.  
T:  
Those parameters are achieved by design characterization on a small sample size from typical  
devices. All values shown in the typical column are within this category.  
D:  
Those parameters are derived mainly from simulations.  
A.1.2 Power Supply  
The MC9S12DT128B utilizes several pins to supply power to the I/O ports, A/D converter, oscillator and  
PLL as well as the digital core.  
The VDDA, VSSA pair supplies the A/D converter and the resistor ladder of the internal voltage regulator.  
The VDDX, VSSX, VDDR and VSSR pairs supply the I/O pins ,VDDR supplies also the internal voltage  
regulator.  
VDD1, VSS1, VDD2 and VSS2 are the supply pins for the digital logic, VDDPLL, VSSPLL supply the  
oscillator and the PLL.  
VSS1 and VSS2 are internally connected by metal.  
VDDA, VDDX, VDDR as well as VSSA, VSSX, VSSR are connected by anti-parallel diodes for ESD  
protection.

MC9S12DT128B Device User Guide — V01.07  
NOTE: In the following context VDD5 is used for either VDDA, VDDR and VDDX; VSS5  
is used for either VSSA, VSSR and VSSX unless otherwise noted.  
IDD5 denotes the sum of the currents flowing into the VDDA, VDDX and VDDR  
pins.  
VDD is used for VDD1, VDD2 and VDDPLL, VSS is used for VSS1, VSS2 and  
VSSPLL.  
IDD is used for the sum of the currents flowing into VDD1 and VDD2.  
A.1.3 Pins  
There are four groups of functional pins.  
A.1.3.1 5V I/O pins  
Those I/O pins have a nominal level of 5V. This class of pins is comprised of all port I/O pins, the analog  
inputs, BKGD pin and the RESET inputs.The internal structure of all those pins is identical, however some  
of the functionality may be disabled. E.g. for the analog inputs the output drivers, pull-up and pull-down  
resistors are disabled permanently.  
A.1.3.2 Analog Reference  
This class is made up by the two VRH and VRL pins.  
A.1.3.3 Oscillator  
The pins XFC, EXTAL, XTAL dedicated to the oscillator have a nominal 2.5V level. They are supplied  
by VDDPLL.  
A.1.3.4 TEST  
This pin is used for production testing only.  
A.1.3.5 VREGEN  
This pin is used to enable the on chip voltage regulator.  
A.1.4 Current Injection  
Power supply must maintain regulation within operating V  
or V range during instantaneous and  
DD  
DD5  
operating maximum current conditions. If positive injection current (V > V  
) is greater than I  
, the  
in  
DD5  
DD5  
injection current may flow out of VDD5 and could result in external power supply going out of regulation.  
Insure external VDD5 load will shunt current greater than maximum injection current. This will be the  
greatest risk when the MCU is not consuming power; e.g. if no system clock is present, or if clock rate is  
very low which would reduce overall power consumption.

A.1.5 Absolute Maximum Ratings  
Absolute maximum ratings are stress ratings only. A functional operation under or outside those maxima  
is not guaranteed. Stress beyond those limits may affect the reliability or cause permanent damage of the  
device.  
This device contains circuitry protecting against damage due to high static voltage or electrical fields;  
however, it is advised that normal precautions be taken to avoid application of any voltages higher than  
maximum-rated voltages to this high-impedance circuit. Reliability of operation is enhanced if unused  
inputs are tied to an appropriate logic voltage level (e.g., either V  
or V  
).

A.2 ATD Characteristics  
This section describes the characteristics of the analog to digital converter.  
The Table A-8 shows conditions under which the ATD operates.  
The following constraints exist to obtain full-scale, full range results:  
V

. This constraint exists since the sample buffer amplifier can not drive

beyond the power supply levels that it ties to. If the input level goes outside of this range it will effectively  
be clipped.

1. Full accuracy is not guaranteed when differential voltage is less than 4.50V

period of 16 ATD clocks.  
A.2.2 Factors influencing accuracy  
Three factors – source resistance, source capacitance and current injection – have an influence on the  
accuracy of the ATD.  
A.2.2.1 Source Resistance:  
Due to the input pin leakage current as specified in Table A-6 in conjunction with the source resistance  
there will be a voltage drop from the signal source to the ATD input. The maximum source resistance R

specifies results in an error of less than 1/2 LSB (2.5mV) at the maximum leakage current. If device or  
operating conditions are less than worst case or leakage-induced error is acceptable, larger values of source  
resistance is allowed.  
A.2.2.2 Source capacitance  
When sampling an additional internal capacitor is switched to the input. This can cause a voltage drop due  
to charge sharing with the external and the pin capacitance. For a maximum sampling error of the input  
voltage 1LSB, then the external filter capacitor, C 1024 * (C – C ).  
f
INS  
INN  
A.2.2.3 Current injection  
There are two cases to consider.  
1. A current is injected into the channel being converted. The channel being stressed has conversion  
values of $3FF ($FF in 8-bit mode) for analog inputs greater than V and $000 for values less than  
RH  
V
unless the current is higher than specified as disruptive conditions.  
RL  
2. Current is injected into pins in the neighborhood of the channel being converted. A portion of this  
current is picked up by the channel (coupling ratio K), This additional current impacts the accuracy  
of the conversion depending on the source resistance.  
The additional input voltage error on the converted channel can be calculated as V  
= K * R *

A.3 NVM, Flash and EEPROM  
NOTE: Unless otherwise noted the abbreviation NVM (Non Volatile Memory) is used for  
both Flash and EEPROM.  
A.3.1 NVM timing  
The time base for all NVM program or erase operations is derived from the oscillator. A minimum  
oscillator frequency f  
is required for performing program or erase operations. The NVM modules  
NVMOSC  
do not have any means to monitor the frequency and will not prevent program or erase operation at  
frequencies above or below the specified minimum. Attempting to program or erase the NVM modules at  
a lower frequency a full program or erase transition is not assured.  
The Flash and EEPROM program and erase operations are timed using a clock derived from the oscillator  
using the FCLKDIV and ECLKDIV registers respectively. The frequency of this clock must be set within  
the limits specified as f  
.
NVMOP  
The minimum program and erase times shown in Table A-11 are calculated for maximum f  
and  
NVMOP  
maximum f . The maximum times are calculated for minimum f  
and a f of 2MHz.

A.5.1.1 POR  
The release level V  
and the assert level V  
are derived from the V Supply. They are also valid  
PORA DD  
PORR  
if the device is powered externally. After releasing the POR reset the oscillator and the clock quality check  
are started. If after a time t no valid oscillation is detected, the MCU will start using the internal self  
CQOUT  
clock. The fastest startup time possible is given by n  
.
uposc  
A.5.1.2 SRAM Data Retention  
Provided an appropriate external reset signal is applied to the MCU, preventing the CPU from executing  
code when VDD5 is out of specification limits, the SRAM contents integrity is guaranteed if after the reset  
the PORF bit in the CRG Flags Register has not been set.  
A.5.1.3 External Reset  
When external reset is asserted for a time greater than PW  
the CRG module generates an internal  
RSTL  
reset, and the CPU starts fetching the reset vector without doing a clock quality check, if there was an  
oscillation before reset.  
A.5.1.4 Stop Recovery  
Out of STOP the controller can be woken up by an external interrupt. A clock quality check as after POR  
is performed before releasing the clocks to the system.

A.5.1.5 Pseudo Stop and Wait Recovery  
The recovery from Pseudo STOP and Wait are essentially the same since the oscillator was not stopped in  
both modes. The controller can be woken up by internal or external interrupts. After t the CPU starts  
wrs  
fetching the interrupt vector.  
A.5.2 Oscillator  
The device features an internal Colpitts and Pierce oscillator. The selection of Colpitts oscillator or Pierce  
oscillator/external clock depends on the XCLKS signal which is sampled during reset.By asserting the  
XCLKS input during reset this oscillator can be bypassed allowing the input of a square wave. Before  
asserting the oscillator to the internal system clocks the quality of the oscillation is checked for each start  
from either power-on, STOP or oscillator fail. t  
specifies the maximum time before switching to the  
CQOUT  
internal self clock mode after POR or STOP if a proper oscillation is not detected. The quality check also  
determines the minimum oscillator start-up time t . The device also features a clock monitor. A  
UPOSC  
Clock Monitor Failure is asserted if the frequency of the incoming clock signal is below the Assert  
Frequency f  
CMFA.

A.5.3.2 Jitter Information  
The basic functionality of the PLL is shown in Figure A-2. With each transition of the clock f , the  
cmp  
deviation from the reference clock f is measured and input voltage to the VCO is adjusted  
ref  
Noise, voltage, temperature and other factors cause slight variations in the control loop resulting in a clock  
jitter. This jitter affects the real minimum and maximum clock periods as illustrated in Figure A-3.

effect of the jitter to a large extent.

A timing diagram of the external multiplexed-bus is illustrated in Figure A-9 with the actual timing  
values shown on table Table A-20. All major bus signals are included in the diagram. While both a data  
write and data read cycle are shown, only one or the other would occur on a particular bus cycle.  
A.8.1 General Muxed Bus Timing  
The expanded bus timings are highly dependent on the load conditions. The timing parameters shown  
assume a balanced load across all outputs.
