With its unique array of configurable blocks, PSoC 3 is a true system level solution providing microcontroller unit (MCU), memory, analog, and digital peripheral functions in a single chip while being AEC-Q100 compliant. 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. The CY8C32 family can handle dozens of data acquisition channels and analog inputs on every general-purpose input/output (GPIO) pin. The CY8C32 family is also a high-performance configurable digital system with some part numbers including interfaces such as USB, and multimaster inter-integrated circuit (I2C). In addition to communication interfaces, the CY8C32 family has an easy to configure logic array, flexible routing to all I/O pins, and a high-performance single cycle 8051 microprocessor core. You can easily create system-level designs using a rich library of prebuilt components and boolean primitives using PSoC Creator, a hierarchical schematic design entry tool. The CY8C32 family provides unparalleled opportunities for analog and digital bill of materials integration while easily accommodating last minute design changes through simple firmware updates.
