1. Architectural Overview
Introducing the CY8C32 family of ultra low-power, flash Programmable System-on-Chip (PSoC
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.

Digital System
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.
