PSoC® 3: CY8C32 Family

Data Sheet

1. Architectural Overview

Introducing the CY8C32 family of ultra low-power, flash Programmable System-on-Chip (PSoC®) devices, part of a scalable 8-bit

PSoC 3 and 32-bit PSoC 5 platform. The CY8C32 family provides configurable blocks of analog, digital, and interconnect circuitry

around a CPU subsystem. The combination of a CPU with a flexible analog subsystem, digital subsystem, routing, and I/O enables

a high level of integration in a wide variety of consumer, industrial, and medical applications.

PSoC’s digital subsystem provides half of its unique

configurability. It connects a digital signal from any peripheral to

any pin through the Digital System Interconnect (DSI). It also

provides functional flexibility through an array of small, fast,

low-power UDBs. PSoC Creator provides a library of prebuilt and

tested standard digital peripherals (UART, SPI, LIN, PRS, CRC,

timer, counter, PWM, AND, OR, and so on) that are mapped to

the UDB array. You can also easily create a digital circuit using

boolean primitives by means of graphical design entry. Each

UDB contains programmable array logic (PAL)/programmable

logic device (PLD) functionality, together with a small state

machine engine to support a wide variety of peripherals.
