CY8C24423A
The PSoC family consists of many programmable
system-on-chips with on-chip Controller devices. These devices
are designed to replace multiple traditional MCU-based system
components with one, low cost single-chip programmable
device. PSoC devices include configurable blocks of analog and
digital logic, and programmable interconnects. This architecture
enables the user to create customized peripheral configurations
that match the requirements of each individual application.
Additionally, a fast CPU, Flash program memory, SRAM data
memory, and configurable I/O are included in a range of
convenient pinouts and packages.
Digital System
The Digital System is composed of four digital PSoC blocks.
Each block is an 8-bit resource that can be used alone or
combined with other blocks to form 8, 16, 24, and 32-bit
peripherals, which are called user modules.

From Core
The PSoC architecture, as shown in the Logic Block Diagram on
page 1, is comprised of four main areas: PSoC Core, Digital
System, Analog System, and System Resources. Configurable
global buses allow all the device resources to be combined into
a complete custom system. Each CY8C24x23A PSoC device
includes four digital blocks and six analog blocks. Depending on
the PSoC package, up to 24 general purpose I/O (GPIO) are also
included. The GPIO provide access to the global digital and
analog interconnects.

PSoC Core
GIE[7:0]
The PSoC Core is a powerful engine that supports a rich feature
set. The core includes a CPU, memory, clocks, and configurable
GPIO (General Purpose I/O).
The M8C CPU core is a powerful processor with speeds up to
24 MHz, providing a four MIPS 8-bit Harvard architecture
microprocessor. The CPU uses an interrupt controller with
multiple vectors, to simplify programming of real time embedded
events. Program execution is timed and protected using the
included Sleep Timer and Watchdog Timer (WDT).
Memory includes 4 KB of Flash for program storage and 256
bytes of SRAM for data storage. Program Flash uses four
protection levels on blocks of 64 bytes, allowing customized
software IP protection.
The PSoC device incorporates flexible internal clock generators,
including a 24 MHz IMO (internal main oscillator) accurate to
±5% over temperature and voltage. A low power 32 kHz ILO
(internal low speed oscillator) is provided for the Sleep Timer and
WDT. If crystal accuracy is desired, the ECO (32.768 kHz
external crystal oscillator) is available for use as a Real Time
Clock (RTC) and can optionally generate a crystal-accurate 24
MHz system clock using a PLL. The clocks, together with
programmable clock dividers (as a System Resource), provide
the flexibility to integrate almost any timing requirement into the
PSoC device.
PSoC GPIOs provide connection to the CPU, digital, and analog
resources of the device. Each pin’s drive mode may be selected
from eight options, allowing great flexibility in external interfacing. Every pin also has the capability to generate a system
interrupt.

The digital blocks can be connected to any GPIO through a
series of global buses that can route any signal to any pin. The
buses also allow for signal multiplexing and for performing logic
operations. This configurability frees your designs from the
constraints of a fixed peripheral controller.
Digital blocks are provided in rows of four, where the number of
blocks varies by PSoC device family. This allows the optimum
choice of system resources for your application. Family
resources are shown in Table 1 on page 4.

Development Tools
Code Generation Tools
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.
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.
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.
PSoC Designer Software Subsystems
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 interfaces. 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
On-Chip Controllers that match your system requirements.
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.
The device editor also supports easy development of multiple
configurations and dynamic reconfiguration. Dynamic
configuration allows for changing configurations at run time.
Hybrid Designs
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.
Document Number: 001-52469 Rev. *C
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.
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.
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.
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
A low cost, high functionality ICE (In-Circuit Emulator) is
available for development support. This hardware has the
capability to program single devices.
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.

Designing with PSoC Designer
Organize and Connect
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.
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 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 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.
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
Generate, Verify, and Debug
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
(I2C-bus, for example), and the logic to control how they interact
with one another (called valuators).
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.
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.
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.
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.
Document Number: 001-52469 Rev. *C
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.
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.

DC Analog Reference Specifications
The following tables list the guaranteed maximum and minimum specifications for the voltage and temperature ranges: 4.75V to 5.25V
and -40°C ≤ TA ≤ 85°C, 3.0V to 3.6V and -40°C ≤ TA ≤ 85°C, respectively. Typical parameters apply to 5V and 3.3V at 25°C and are
for design guidance only.
The guaranteed specifications are measured through the Analog Continuous Time PSoC blocks. The power levels for AGND refer to
the power of the Analog Continuous Time PSoC block. The power levels for RefHi and RefLo refer to the Analog Reference Control
register. The limits stated for AGND include the offset error of the AGND buffer local to the Analog Continuous Time PSoC block.
Reference control power is high.
Note Avoid using P2[4] for digital signaling when using an analog resource that depends on the Analog Reference. Some coupling
of the digital signal may appear on the AGND.

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 8.1 kΩ resistance and the external capacitor.

16. Maximum CPU frequency is 12 MHz nominal at 3.3V. With the CPU clock divider set to 1, the external clock must adhere to the maximum frequency and duty cycle
requirements.
17. If the frequency of the external clock is greater than 12 MHz, the CPU clock divider must be set to 2 or greater. In this case, the CPU clock divider ensures that the
fifty percent duty cycle requirement is met.

18. FSCLI2C is derived from SysClk of the PSoC. This specification assumes that SysClk is operating at 24 MHz, nominal. If SysClk is at a lower frequency, then the
FSCLI2C specification adjusts accordingly.
19. A Fast-Mode I2C-bus device can be used in a Standard-Mode I2C-bus system, but the requirement TSUDATI2C ≥ 250 ns must then be met. This is automatically 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 + TSUDATI2C = 1000 + 250 = 1250 ns (according to the Standard-Mode I2C-bus specification) before the SCL line is released.

CY3210-24X23 Evaluation Pod (EvalPod)
PSoC EvalPods are pods that connect to the ICE In-Circuit
Emulator (CY3215-DK kit) to allow debugging capability. They
can also function as a standalone device without debugging
capability. The EvalPod has a 28-pin DIP footprint on the bottom
for easy connection to development kits or other hardware. The
top of the EvalPod has prototyping headers for easy connection
to the device's pins. CY3210-24X23 provides evaluation of the
CY8C24x23A PSoC device family.
