3.0.1 The Analog Multiplexer System  
The Analog Mux Bus can connect to every GPI/O pin in ports 0-5.  
Pins are 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. It is split into two  
sections for simultaneous dual-channel processing. An  
additional 8:1 analog input multiplexer provides a second path to  
bring Port 0 pins to the analog array.  
Switch control logic enables selected pins to precharge continu-  
ously under hardware control. This enables capacitive  
measurement for applications such as touch sensing. Other  
multiplexer applications include:  
Track pad, finger sensing.  
Chip-wide mux that allows analog input from up to 48 I/O pins.  
Crosspoint connection between any I/O pin combinations.  
When designing capacitive sensing applications, refer to the  
Resources > Application Notes. In general, and unless otherwise  
noted in the relevant Application Notes, the minimum  
signal-to-noise ratio (SNR) for CapSense applications is 5:1.

5.1.4 Code Generation Tools  
5. 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.  
5.1 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.  
5.1.1 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.  
5.1.5 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 I/O 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.  
5.1.2 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.  
5.1.6 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.  
5.2 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 ICE (In-Circuit Emulator) is  
available for development support. This hardware has the  
capability to program single devices.  
5.1.3 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.

6.3 Organize and Connect  
6. Designing with PSoC Designer  
You can build signal chains at the chip level by interconnecting  
user modules to each other and the I/O pins, or connect system  
level inputs, outputs, and communication interfaces to each  
other with valuator functions.  
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.  
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.  
6.4 Generate, Verify, and Debug  
6.1 Select Components  
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.  
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).  
2
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.  
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.  
6.2 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 In-Circuit Emulator (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  
property, and other information you may need to successfully  
implement your design.

Notes  
1. These are the ISSP pins, which are not High Z at POR. See the PSoC Programmable System-on-Chip Technical Reference Manual for details.  
2. The center pad on the QFN package should be connected to ground (Vss) for best mechanical, thermal, and electrical performance. If not connected to ground, it  
should be electrically floated and not connected to any other signal.

9. Register Reference  
This section lists the registers of the CY8C24x94 PSoC device family. For detailed register information, reference the  
PSoC Programmable System-on-Chip Technical Reference Manual.  
9.1 Register Conventions  
9.2 Register Mapping Tables  
The register conventions specific to this section are listed in the  
following table.  
The PSoC device has a total register address space of 512  
bytes. The register space is referred to as I/O 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.

of 25,000 maximum cycles each, or 36x4 blocks of 12,500 maximum cycles each (to limit the total number of cycles to 36x50,000 and that no single block ever sees  
more than 50,000 cycles).  
For the full industrial range, the user must employ a temperature sensor user module (FlashTemp) and feed the result to the temperature argument before writing.

When bypassed by a capacitor on P2[4], the noise of the analog ground signal distributed to each block is reduced by a factor of up  
to 5 (14 dB). This is at frequencies above the corner frequency defined by the on-chip 8.1k resistance and the external capacitor.

14. A Fast-Mode I2C-bus device can be used in a Standard-Mode I2C-bus system, but the requirement t  
Š 250 ns must then be met. This automatically is the case  
SU;DAT  
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 t + t = 1000 + 250 = 1250 ns (according to the Standard-Mode I2C-bus specification) before the SCL line is released.
