PSoC® 3: CY8C36 Family
Data Sheet
Programmable System-on-Chip (PSoC®)
General Description
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. The CY8C36 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 CY8C36 family can handle dozens of data acquisition channels and analog inputs on
every general-purpose input/output (GPIO) pin. The CY8C36 family is also a high-performance configurable digital system with some
part numbers including interfaces such as USB, multi-master inter-integrated circuit (I2C), and controller area network (CAN). In
addition to communication interfaces, the CY8C36 family has an easy to configure logic array, flexible routing to all I/O pins, and
current DAC 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 CY8C36
family provides unparalleled opportunities for analog and digital bill of materials integration while easily accommodating last minute
design changes through simple firmware updates.
