Embedded Systems: An Integrated Approach by Pearson

Introduction

 e term SoC was mentioned in Chapter 1. So we know that an MCU with a large

number of peripherals is called an SoC, for ‘System on chip’. Each of the peripherals on

an SoC is usually programmable, and so the term PSoC can have a general meaning.

But in this chapter, we discuss a very specifi c product line of Cypress Semiconductors

designated as PSoC. We discuss the special features of Cypress’s PSoC, which has

become very popular in the embedded systems world and has found many applications

for itself. PSoC is a family of embedded processors with a simple 8-bit M8C core in

PSoC1, a more sophisticated 8-bit 8051 core in PSoC3,
