PSoC® 5LP: CY8C56LP Family
Datasheet
Programmable System-on-Chip (PSoC®)
General Description
With its unique array of configurable blocks, PSoC® 5LP is a true system level solution providing MCU, memory, analog, and digital
peripheral functions in a single chip. The CY8C56LP 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 CY8C56LP family can handle dozens of data acquisition channels and analog inputs on every
general-purpose input/output (GPIO) pin. The CY8C56LP family is also a high performance configurable digital system with some
part numbers including interfaces such as USB, multimaster inter-integrated circuit (I2C), and controller area network (CAN). In
addition to communication interfaces, the CY8C56LP family has an easy to configure logic array, flexible routing to all I/O pins, and
a high performance 32-bit ARM® Cortex™-M3 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 CY8C56LP
family provides unparalleled opportunities for analog and digital bill of materials integration while easily accommodating last minute
design changes through simple firmware updates.
