32-Bit Proprietary Microcontroller

LSI Network Security System

MB91401

■ DESCRIPTION

The MB91401 is a network security LSI incorporating a Fujitsu’s 32-bit, FR-family RISC microcontroller with 10/

100Base-T MAC Controller, encryption function and authentication function. The LSI contains an encryption

authentication hardware accelerator that boosts the LSI’s performance for encryption and authentication commu-

nication (IKE/IPsec/SSL) to be demanded further.

The MAC controller has a packet filtering function that reduces the load on the CPU for an increasing amount of

packet processing. In addition, the board has the External interface for high-speed data communication with

various external hosts, USB ports as general-purpose interfaces, and various card interfaces.

■ FEATURES

• Encryption and authentication processing by hardware accelerator function

The LSI performs processing five times faster than by the conventional combination of encryption/authentication

hardware macros and software or about 400 times faster than by software only. In addition, CPU processing load

factor to be involved in the encryption and the authentication processing can be decreased to 1/5 or less.

Also, the LSI uses the embedded accelerator to execute that public-key encryption algorithm about 100 times

faster than by software processing, which generally puts an extremely heavy load microcontrollers.

■ HANDLING DEVICES

Preventing Latch-up

When a voltage that is higher than V^DDEand a voltage that is lower than VSS are impressed to the input terminal

and the output terminal in CMOS IC or the voltage that exceeds ratings between VDDE to VSS is impressed, the

latch-up phenomenon might be caused. If latch-up occurs, the supply current increases rapidly, sometimes

resulting in thermal breakdown of the device. Use meticulous care not to let any voltage exceed the maximum

rating during device operation.

Separation of power supply pattern

Analog PLL (APLL at the following) is installed in this LSI. The power supply for VCO and for digital is separated

in LSI so that the oscillation characteristic of APLL may receive the influence of power supply variation.

Therefore, the power supply is recommended to be separated also on the mounting base.

• Separation of power supply pattern (recommended)

Take measures to reduce impedance, for example, by using as wide a power pattern as possible.

The recommendation example is shown as follows.

• For two power supplies (for digital and for VCO)

It is advisable to provide a digital power-supply (a) and VCO power-supply (b) and connect them to the LSI’s

equivalents, respectively.

Treatment of the unused pins

Leaving unused input pins open results in a malfunction, so process the pull-up or pull-down.

Treatment of OPEN pins

Be sure to use open pins in open state.

Treatment of output pins

A large current may flow to an output pin left connected to the power-supply, another output pin, or to a high

capacitance load. Leaving the output pin that way for an extended period of time degrades the device. Use

meticulous care in using the device not to exceed the absolute maximum rating.

About Mode (MDI2 to MDI0, VPD) pin and Test (TEST3 to TEST0) pin

Connect these pins directly to VDDE or VSS. To prevent the device from entering test mode accidentally due to

noise, minimize the lengths of the patterns between individual mode pins and VDDE or VSS on the PC board

as possible and connect them with as low an impedance as possible.

About power supply pins

In products with multiple VDDE, VDDI or VSS pins, the pins of the same potential are internally connected in

the device to avoid abnormal operations including latch-up. However you must connect the pins to external power

supply and a ground line to lower the electro-magnetic emission level to prevent abnormal operation strobe

signals caused by the rise in the ground level, and to conform to the total output current rating.

The power pins should be connected to VDDE, VDDI and VSS of this device at the lowest possible impedance

from the current supply source.

It is also advisable to connect a ceramic bypass capacitor of approximately 0.1 µF between VDDE and VSS,

and between VDDI and VSS near this device.

Crystal Oscillator Circuit

Noise near the OSCEA terminal may cause the MB91401 to malfunction.

Design the circuit board so that OSCEA terminal, OSCEB terminal and the crystal oscillator, and the bypass

capacitor to ground are located as close to the device as possible.

It is strongly recommended to design the PC board artwork with the OSCEA terminal and OSCEB terminal

surrounded by ground plane because stable operation can be expected with such a layout.

• Notes when encryption/authentication accelarator is used

When using the encryption/authentication installed in this LSI, it is necessary to the following notes.

32-bit data bus

The encryption/authentication accelerator fetches data from the area storing data to be subject to encryption/

authentication and encrypts or authenticates the data without CPU intervention. In the encryption processing,

write is done in the area where it wants to store the data after the encryption is processed.

Holding request withdrawal demand function OFF

When accessing to the storage destination of encryption/authentication processing data, the encryption/authen-

tication accelerator should hold an internal bus of this LSI.

Therefore, when the encryption/authentication accelerator are used, it should be set that the holding request

withdrawal doesn’t demand.

Please set the HRCL register that sets the interrupt level that becomes the standard of the holding request

withdrawal demand generation to "10000" in the FR core.

For NMIs, the hold request cancel request occurs regardless of the HRCL register setting. When the encryption/

authentication accelerator is used, therefore, NMI input may cause encryption/authentication to fail to result

correctly. In that case, the correspondence said that it will execute the encryption/authentication processing

under execution again is necessary.

• Notes as device

Treatment of Unused Input Pins

It causes the malfunction that the unused input terminal is made open, and do the processing such as 1 stack

or 0 stacks.

About Mode pins (MDI2 to MDI0)

Connect these pins with the input buffer by 1 to 1 to prevent the malfunction by the noise, and connect directly

to VDD or VSS outside of ASIC.

Operation at start-up

Specify set initialization reset (INIT) with the terminal INITXI when you turn on the power supply.

Moreover, connect "L" level input to the terminal INITXI until the input clock is steady.

About watch dog timer

The watchdog timer function of this macro monitors a program to check whether it delays a reset within a certain

period of time. If the program runs out of control and fails to delay the reset, the watchdog timer function resets

the CPU.

Therefore, it keeps operating until reset is specified when the watchdog timer function is made effective once.

Exceptionally, the reset postponement is automatically done under the condition that the program execution of

CPU stops. Refer to the paragraph of the function explanation of the watchdog timer for the condition of applying

to this exception.

There is a possibility that watchdog reset is not generated when entering the above-mentioned state by the

reckless driving of the system. In that case, please specify reset (INIT) from external INITX terminal.

Restrictions

• Clock control block

• Secure the clock stability waiting time at "L" input to INITXI.

• When entering the standby mode, use the following sequences after using the synchronous standby mode

(TBCR:set at the bit8 SYNCS bit of timebase counter control register).

• The following operations may be performed when the instruction immediately followed by a DIVOU/DIVOS

instruction is (a) halted by a user interrupt or NMI, (b) single-stepped, or (c) breaks in response to a data event

or emulator menu:

(1) The D0 and D1 flags are updated in advance.

(2) An EIT handling routine (user interrupt, NMI, or emulator) is executed.

(3) Upon returning from the EIT, the DIVOU/DIVOS instruction is executed and the D0 and D1 flags are

updated to the same values as in (1) .

• The following operations are performed when the ORCCR/STILM/MOVRi and PS instructions are executed.

(2) Executing of EIT processing routine (user interrupt • NMI)

(3) Upon returning from the EIT, the above instructions are executed and the PS register is updated to the

same value as in (1) .

• Since some instructions manipulate the PS register earlier, the following exceptions may cause the interrupt

handler to break or the PS flag to update its display setting when the debugger is being used. As the micro-

controller is designed to carry out reprocessing correctly upon returning from such an EIT event in either case,

it performs operations before and after the EIT as specified.

1. When (a) user interrupt and NMI are accepted or (b) step is executed or (c) break is done by the data

event or the menu of the emulator in the instruction immediately before the instruction of DIV0U/DIV0S,

the following operation might be done.

(1) The D0 and D1 flags are updated in advance.

(2) An EIT handling routine (user interrupt, NMI, or emulator) is executed.

(1) Upon returning from the EIT, the DIVOU/DIVOS instruction is executed and the D0 and D1 flags are

updated to the same values as in (3) .

2. When ORCCR, STILM, MOV Ri, and PS each instruction is executed to permit interrupt with the user

interrupt and the NMI factor generated, the following operation is done.

(1) The PS register is updated in advance.

(2) The EIT processing routine (user interrupt, NMI or emulator) is executed.

(3) Upon returning from the EIT, the above instructions are executed and the PS register is updated to

the same value as in (1).

• Do not access the data to the cache memory at the control register of the instruction cash and RAM mode

immediately before the instruction of RETI.

• If one of the instructions listed below is executed, the SSP or USP* value is not used as the R15 value and,

as a result, an incorrect value is written to memory.

■ NOTES OF DEBUG

Step execution of RETI instruction

In an environment where interrupts frequently occur during single-step execution, only the relevant interrupt

processingroutinesareexecutedrepeatedlyduringsingle-stepexecutionoftheRETIinstruction. Thiswillprevent

the main routine and low-interrupt-level programs from being executed.

Do not execute step of RETI instruction for escape.

When the relevant interrupt routine no longer requires being debugged, disable the relevant interrupt and perform

debugging.

Operand break

Do not set the access which is used for area, including the address of system stack pointer, to the target of data

event break.

Interrupt handler to NMI request (tool)

To prevent the malfunction because of the noise problem of DSU pin when ICE is unconnected, the following

programs are added to the interrupt handler by the cause flag, which is only set by the break request from ICE.

ICE can be used even if this program is added.

Location to added

The following interrupt handler

Interrupt resource

Interrupt number

Offset

: NMI request (tool)

: 13 (decimal), 0D (hexadecimal)

: 3C8^H

TBR is default address. : 000FFFC8H

Additional program

STM (R0, R1)

LDI #B00^H, R0 ; B00H is address of the break resource register.

LDI #0, R1

STB R1, @R0 ; Clear the break resource register.

LDM (R0, R1)

RETI

Trace mode

If the trace mode is set to "Full trace mode" during debug (in full trace mode, built-in FIFO is used as output

buffer, the trace memory of the main body of ICE is used, and the trace data lost is not occurred), the electric

current is increased and D-busDMA access may be lost.

Also, the trace data lost may be occurred.

To take the measures, do not set full trace mode.

Simultaneous generation of a software break and a user interrupt/NMI

When a software break and a user interrupt/NMI occur simultaneously, the emulator debugger may react as

follows.

• The debugger stops pointing to a location other than the programmed breakpoints.

• The halted program is not re-executed correctly.

When these problems are occurred, not only the software break, the hardware break should also be used. Do

not set the break to the corresponding location when using monitor debugger.

XXXX XXXXH

0000 0000H

Registers R0 to R15 are general-purpose registers. The registers are used as the accumulator and memory

access pointers for CPU operations.

Of these 16 registers, the registers listed below are intended for special applications, for which some instructions

are enhanced.

R13: Virtual accumulator

R14: frame pointer

R15:Stack pointer

The initial values of R0 to R14 after a reset are indeterminate. R15 is initialized to 00000000^H(SSP value).

■ MODE SETTINGS

The FR family uses the mode pins (MDI2 to MDI0) and the mode register (MODR) to set the operation mode.

• Mode Pins

Three mode pins MDI[2], MDI[1], and MDI[0] are used to specify a mode vector fetch or test mode.

Setting MDI2 to MDI0 to "010", USRTEST is set to "1" and the device operates in the user circuit test mode. The

FR71 core is suspended in the user circuit test mode while SYSCLK and MCLKO are operating. The reserved

modes include the FR71 core test mode. In this case, the signal at the FRTEST pin becomes "1" and enters the

FR71 core test mode. If the FRTEST pin = "1", that circuit configuration is required which allows the separately

defined pins of the FR71 core to be controlled and monitored from the outside of the chip.

• Mode Register (MODR)

The data written to the mode register (MODR) by hardware using a mode vector fetch is called mode data.

When this register is set by hardware, the CPU operates in the operation mode corresponding to the register

setting.

The mode register is set only by an INIT-level reset cause. The user program cannot access this register.

However, as an exception, when the macro shifts to emulation mode by INTE instruction, or shifts to emulation

mode by a break at a debug using ICE, this register is mapped at 0000_07FD^H. Select this function when using

ICE, perform the mode data setting before the program loading by writing a appropriate value to this register.

Note : No data is existed in the address (0000_07FFH ) in the mode register of the FR family.

[bit1, bit0] WTH1, WTH0 (Bus width setting bits)

These bits specify the bus width. The value of the bits is set in the DBW1 and DBW0 bits in ACR0 (CSO area).

Set these bits to a value other than “11”.

Bus mode

In bus mode, the operations of internal ROM and the external access functions are controlled according to the

mode setting pins (MD2 to MD0) and the values of mode data.

Although the FR71 architecture supports this bus mode, this macro cannot use the single-chip or internal ROM/

external bus mode but can use the external ROM/external bus mode only.

Access mode

Access mode indicates the mode that controls the external data bus width, and is specified by the WTH1/WTH0

bits, and the DBW1/DBW0 bits within ACR0 to ACR7 (Area Configuration Registers).

Bus mode

The FR family has three bus modes described below. Please refer to “■ MEMORY SPACE” for details.

(2) NMI (Non Maskable Interrupt)

NMIs have the highest priority among the interrupt sources handled by this module.

An NMI is always selected whenever other types of interrupt sources occur at the same time.

• If an NMI occurs, the interrupt controller passes the information to the CPU :

Interrupt level : 15 (01111^B)

Interrupt number : 15 (0001111B)

• NMI detection

NMIs are set and detected by the external interrupt/NMI controller. This module only generates an interrupt

level, interrupt number, and MHALTI upon NMI request.

• Suppressing DMA transfer upon NMI request

When an NMI request occurs, the MHALTI bit in the HRCL register is set to "1", suppressing DMA transfer. To

permit DMA transfer, clear the MHALTI bit to "0" at the end of the NMI routine.

*1 : <About the output short-circuit current>

Output short-circuit current I^OSis the maximum current that flows when the output pin is connected to VDDE

or VSS (within the maximum rating) . The current is “the short-circuit current per differential output pin.” As the

USB I/O buffer is a differential output, the short-circuit current should be considered for both of the output pins.

The switching threshold voltage of the USB I/O buffer’s single-end receiver is set within the range from

VIL (Max) = 0.8 V to VIH (Min) = 2.0 V (TTL input standard) .

For VIH and VIL, the LSI has some hysteresis to reduce noise susceptibility.

*2 : <Input Levels V^DI, VCM>

A differential receiver is used to receive USB differential data signals.

The differential receiver has a differential input sensitivity of 200 mV when the differential data input falls within

the range from 0.8 V to 2.5 V with respect to the local ground reference level.

The above voltage range is referred to as common-mode input voltage range.

*1 : The AC characteristics of the USB interface conform to USB Specification Revision 1.1.

*2 : <Driver Characteristics TFR, TFF, TFRFM>

These items specify the differential data signal rise (trise) and fall (tfall) times.

These are defined as the times between 10% to 90% of the output signal voltage.

For the full-speed buffer, trise and tfall are specified such that the tr/tf ratio falls within ± 10% to minimize RFI

radiation.

*3 : <Driver Characteristics ZDRV>

USB full-speed connection is performed via a shielded twisted-pair cable at a characteristic impedance of

90 Ω ± 15%. The USB Standard stipulates that the USB driver’s output impedance must be within the range

of 28 Ω to 44Ω. The USB Standard also stipulates that a discrete serial resistor (R^S) must be added to have

balance while satisfying the above standard.

The output impedance of the USB I/O buffer on this LSI is about 3 Ω to 19 Ω. Serial resistor RS to be added

must be 25 Ω to 30 Ω (27 Ω recommended) .

Capacitor CL of 50 pF must be added as well.
