The Analog Multiplexer System  
The Analog System  
The Analog Mux Bus can connect to every GPIO pin. Pins may  
be connected to the bus individually or in any combination. The  
bus also connects to the analog system for analysis with  
comparators and analog-to-digital converters. An additional 8:1  
analog input multiplexer provides a second path to bring Port 0  
pins to the analog array.  
The Analog System consists of 4 configurable blocks that allow  
the creation of complex analog signal flows. Analog peripherals  
are very flexible and may be customized to support specific  
application requirements. Some of the common PSoC analog  
functions for this device (most available as user modules) are:  
Analog-to-digital converters (single or dual, with 8-bit or 10-bit  
resolution)  
Switch control logic enables selected pins to precharge  
continuously under hardware control. This enables capacitive  
measurement for applications such as touch sensing. Other  
multiplexer applications include:  
Pin-to-pin comparator  
Single-ended comparators (up to 2) with absolute (1.3V)  
reference or 8-bit DAC reference  
Track pad, finger sensing.  
1.3V reference (as a System Resource)  
Chip-wide mux that allows analog input from any IO pin.  
Crosspoint connection between any IO pin combinations.  
In most PSoC devices, analog blocks are provided in columns of  
three, which includes one CT (Continuous Time) and two SC  
(Switched Capacitor) blocks. The CY8C21x34 devices provide  
limited functionality Type “E” analog blocks. Each column  
contains one CT Type E block and one SC Type E block. Refer  
to the PSoC Programmable System-on-Chip™ Technical  
Reference Manual for detailed information on the CY8C21x34’s  
Type E analog blocks.

Code Generation Tools  
Development Tools  
PSoC Designer supports multiple third party C compilers and  
assemblers. The code generation tools work seamlessly within  
the PSoC Designer interface and have been tested with a full  
range of debugging tools. The choice is yours.  
PSoC Designer is a Microsoft® Windows-based, integrated  
development  
environment  
for  
the  
Programmable  
System-on-Chip (PSoC) devices. The PSoC Designer IDE runs  
on Windows XP or Windows Vista.  
This system provides design database management by project,  
an integrated debugger with In-Circuit Emulator, in-system  
programming support, and built-in support for third-party  
assemblers and C compilers.  
Assemblers. The assemblers allow assembly code to merge  
seamlessly with C code. Link libraries automatically use absolute  
addressing or are compiled in relative mode, and linked with  
other software modules to get absolute addressing.  
PSoC Designer also supports C language compilers developed  
specifically for the devices in the PSoC family.  
C Language Compilers. C language compilers are available  
that support the PSoC family of devices. The products allow you  
to create complete C programs for the PSoC family devices.  
PSoC Designer Software Subsystems  
The optimizing C compilers provide all the features of C tailored  
to the PSoC architecture. They come complete with embedded  
libraries providing port and bus operations, standard keypad and  
display support, and extended math functionality.  
System-Level View  
A drag-and-drop visual embedded system design environment  
based on PSoC Express. In the system level view you create a  
model of your system inputs, outputs, and communication inter-  
faces. You define when and how an output device changes state  
based upon any or all other system devices. Based upon the  
design, PSoC Designer automatically selects one or more PSoC  
Mixed-Signal Controllers that match your system requirements.  
Debugger  
The PSoC Designer Debugger subsystem provides hardware  
in-circuit emulation, allowing you to test the program in a physical  
system while providing an internal view of the PSoC device.  
Debugger commands allow the designer to read and program  
and read and write data memory, read and write IO registers,  
read and write CPU registers, set and clear breakpoints, and  
provide program run, halt, and step control. The debugger also  
allows the designer to create a trace buffer of registers and  
memory locations of interest.  
PSoC Designer generates all embedded code, then compiles  
and links it into a programming file for a specific PSoC device.  
Chip-Level View  
The chip-level view is a more traditional Integrated Development  
Environment (IDE) based on PSoC Designer 4.4. Choose a base  
device to work with and then select different onboard analog and  
digital components called user modules that use the PSoC  
blocks. Examples of user modules are ADCs, DACs, Amplifiers,  
and Filters. Configure the user modules for your chosen  
application and connect them to each other and to the proper  
pins. Then generate your project. This prepopulates your project  
with APIs and libraries that you can use to program your  
application.  
Online Help System  
The online help system displays online, context-sensitive help  
for the user. Designed for procedural and quick reference, each  
functional subsystem has its own context-sensitive help. This  
system also provides tutorials and links to FAQs and an Online  
Support Forum to aid the designer in getting started.  
In-Circuit Emulator  
The device editor also supports easy development of multiple  
configurations and dynamic reconfiguration. Dynamic  
configuration allows for changing configurations at run time.  
A low cost, high functionality In-Circuit Emulator (ICE) is  
available for development support. This hardware has the  
capability to program single devices.  
Hybrid Designs  
The emulator consists of a base unit that connects to the PC by  
way of a USB port. The base unit is universal and operates with  
all PSoC devices. Emulation pods for each device family are  
available separately. The emulation pod takes the place of the  
PSoC device in the target board and performs full speed (24  
MHz) operation.  
You can begin in the system-level view, allow it to choose and  
configure your user modules, routing, and generate code, then  
switch to the chip-level view to gain complete control over  
on-chip resources. All views of the project share a common code  
editor, builder, and common debug, emulation, and programming  
tools.

property, and other information you may need to successfully  
implement your design.  
Designing with PSoC Designer  
The development process for the PSoC device differs from that  
of a traditional fixed function microprocessor. The configurable  
analog and digital hardware blocks give the PSoC architecture a  
unique flexibility that pays dividends in managing specification  
change during development and by lowering inventory costs.  
These configurable resources, called PSoC Blocks, have the  
ability to implement a wide variety of user-selectable functions.  
Organize and Connect  
You can build signal chains at the chip level by interconnecting  
user modules to each other and the IO pins, or connect system  
level inputs, outputs, and communication interfaces to each  
other with valuator functions.  
In the system-level view, selecting a potentiometer driver to  
control a variable speed fan driver and setting up the valuators  
to control the fan speed based on input from the pot selects,  
places, routes, and configures a programmable gain amplifier  
(PGA) to buffer the input from the potentiometer, an analog to  
digital converter (ADC) to convert the potentiometer’s output to  
a digital signal, and a PWM to control the fan.  
The PSoC development process can be summarized in the  
following four steps:  
1. Select components  
2. Configure components  
3. Organize and Connect  
4. Generate, Verify, and Debug  
In the chip-level view, perform the selection, configuration, and  
routing so that you have complete control over the use of all  
on-chip resources.  
Select Components  
Both the system-level and chip-level views provide a library of  
prebuilt, pretested hardware peripheral components. In the  
system-level view, these components are called “drivers” and  
correspond to inputs (a thermistor, for example), outputs (a  
brushless DC fan, for example), communication interfaces  
(I C-bus, for example), and the logic to control how they interact  
with one another (called valuators).  
Generate, Verify, and Debug  
When you are ready to test the hardware configuration or move  
on to developing code for the project, perform the “Generate  
Application” step. This causes PSoC Designer to generate  
source code that automatically configures the device to your  
specification and provides the software for the system.  
2
In the chip-level view, the components are called “user modules”.  
User modules make selecting and implementing peripheral  
devices simple, and come in analog, digital, and mixed signal  
varieties.  
Both system-level and chip-level designs generate software  
based on your design. The chip-level design provides application  
programming interfaces (APIs) with high level functions to  
control and respond to hardware events at run-time and interrupt  
service routines that you can adapt as needed. The system-level  
design also generates a C main() program that completely  
controls the chosen application and contains placeholders for  
custom code at strategic positions allowing you to further refine  
the software without disrupting the generated code.  
Configure Components  
Each of the components you select establishes the basic register  
settings that implement the selected function. They also provide  
parameters and properties that allow you to tailor their precise  
configuration to your particular application. For example, a Pulse  
Width Modulator (PWM) User Module configures one or more  
digital PSoC blocks, one for each 8 bits of resolution. The user  
module parameters permit you to establish the pulse width and  
duty cycle. Configure the parameters and properties to  
correspond to your chosen application. Enter values directly or  
by selecting values from drop-down menus.  
A complete code development environment allows you to  
develop and customize your applications in C, assembly  
language, or both.  
The last step in the development process takes place inside the  
PSoC Designer’s Debugger subsystem. The Debugger  
downloads the HEX image to the ICE where it runs at full speed.  
Debugger capabilities rival those of systems costing many times  
more. In addition to traditional single-step, run-to-breakpoint and  
watch-variable features, the Debugger provides a large trace  
buffer and allows you define complex breakpoint events that  
include monitoring address and data bus values, memory  
locations and external signals.  
Both the system-level drivers and chip-level user modules are  
documented in data sheets that are viewed directly in the PSoC  
Designer. These data sheets explain the internal operation of the  
component and provide performance specifications. Each data  
sheet describes the use of each user module parameter or driver

Register Mapping Tables  
The PSoC device has a total register address space of 512 bytes. The register space is referred to as IO space and is divided into  
two banks. The XOI bit in the Flag register (CPU_F) determines which bank the user is currently in. When the XOI bit is set the user  
is in Bank 1.  
Note In the following register mapping tables, blank fields are Reserved and must not be accessed.

the case if the device does not stretch the LOW period of the SCL signal. If such device does stretch the LOW period of the SCL signal, it must output the next  
data bit to the SDA line trmax + tSU;DAT = 1000 + 250 = 1250 ns (according to the Standard-Mode I2C-bus specification) before the SCL line is released.
