General Description

With its unique array of configurable blocks, PSoC? 3 is a true ystem level solution providing microcontroller unit (MCU), memory, analog, and digital peripheral functions in a single chip. The CY8C32 family offers a modern method of signal acquisition, signal processing, and control with high accuracy, high bandwidth, and high flexibility. Analog capability spans the range from thermocouples (near DC voltages) to ultrasonic signals.
