The CY8C54LP 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 CY8C54LP family can handle dozens of data acquisition channels and analog inputs on every general-purpose input/output (GPIO) pin. The CY8C54LP 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 CY8C54LP 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 CY8C54LP family provides unparalleled opportunities for analog and digital bill of materials integration while easily accommodating last minute design changes through simple firmware updates.
