CY8C28xxx
PSoC Functional Overview
The PSoC family consists of many devices with On-Chip
Controllers. These devices are designed to replace multiple
traditional MCU based system components with one low cost
single chip programmable component. A PSoC device includes
configurable analog blocks, digital blocks, and interconnections.
This architecture enables the user to create customized
peripheral configurations to match the requirements of each
individual application. In addition, a fast CPU, Flash program
memory, SRAM data memory, and configurable I/O are included
in a range of convenient pinouts and packages.
The CY8C28xxx group of PSoC devices described in this data
sheet have multiple resource configuration options available.
Therefore, not every resource mentioned in this data sheet is
available for each CY8C28xxx subgroup. The CY8C28x45
subgroup has a full feature set of all resources described. There
are six more segmented subgroups that allow designers to use
a device with only the resources and functionality necessary for
a specific application. See
Table 2
on page 6 to determine the
resources available for each CY8C28xxx subgroup. The same
information is also presented in more detail in the
Ordering Infor-
mation
section.
The architecture for this specific PSoC device family, as shown
in the
System Block Diagram
on page 1, consists of four main
areas: PSoC Core, Digital System, Analog System, and System
Resources. The configurable global bus system allows all the
device resources to be combined into a complete custom
system. PSoC CY8C28xxx family devices have up to six I/O
ports that connect to the global digital and analog interconnects,
providing access to up to 12 digital blocks and up to 16 analog
blocks.
alone or combined with other blocks to create 8, 16, 24, and
32-bit peripherals, which are called user modules. The digital
blocks can be connected to any GPIO through a series of global
buses that can route any signal to any pin.

The PSoC Core
The PSoC Core is a powerful engine that supports a rich feature
set. The core includes a CPU, memory, clocks, and configurable
general Purpose I/O (GPIO). The M8C CPU core is a powerful
processor with speeds up to 24 MHz, providing a four MIPS 8-bit
Harvard architecture microcontroller.
Memory encompasses 16K bytes of Flash for program storage,
1K bytes of SRAM for data storage. The PSoC device incorpo-
rates flexible internal clock generators, including a 24 MHz
internal main oscillator (IMO) accurate to 2.5% over temperature
and voltage. A low power 32 kHz internal low speed oscillator
(ILO) is provided for the sleep timer and watch dog timer (WDT).
The 32.768 kHz external crystal oscillator (ECO) is available for
use as a real time clock (RTC) and can optionally generate a
crystal-accurate 24 MHz system clock using a PLL.
PSoC GPIOs provide connections to the CPU, and digital and
analog resources. Each pin’s drive mode may be selected from
8 options, which allows great flexibility in external interfacing.
Every pin also has the capability to generate a system interrupt
on high level, low level, and change from last read.

The Analog System
The Analog System is composed of up to 16 configurable analog
blocks, each containing an opamp circuit that allows the creation
of complex analog signal flows. Some devices in this PSoC
family have an analog multiplex bus that can connect to every
GPIO pin. This bus can also connect to the analog system for
analysis with comparators and analog-to-digital converters. It
can be split into two sections for simultaneous dual-channel
processing.
Some of the more common PSoC analog functions (most
available as user modules) are:
