CY8C38xxx | Cypress Semiconductor


With its unique array of configurable blocks, PSoC® 3 is a true system-level solution. The CY8C38 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 CY8C38 family can handle dozens of data acquisition channels and analog inputs on every GPIO pin. The CY8C38 family is also a high performance configurable digital system with some part numbers including interfaces such as USB, multi-master I2C, and CAN. In addition to communication interfaces, the CY8C38 family has an easy to configure logic array, flexible routing to all IO pins, and a high performance single cycle 8051 microprocessor core. Designers can easily create system-level designs using a rich library of prebuilt components and a schematic entry tool that uses the standard design blocks and Boolean primitives. The CY8C38 family provides unparalleled opportunities for analog and digital bill of materials (BOM) integration while easily accommodating last minute design changes through simple firmware updates.

Trainings On-Demand
  • Training on-demand is web-based training that can be used to learn new subjects at your own pace and time. They are usually between 15 minutes to 2 hours
  • Webinars are live web-based events featuring a presenter on a live topic and attendees have the opportunity to interact with the presenter and ask questions. Webinars are archived and can be watched later.
  • The workshop is a live training event held by Cypress and its partners - registration is required.
  • Videos (typically less than 10 minutes) focus on specific topics - they can provide training on a very specific subject or demonstrate a new kit / feature
  • Blogs are informal communication for Cypress to interact with its customers. Different blogs focus on different topics. The PSoC Insiders blog is maintained by the PSoC Applications team and focus on provided training on various topics
  • My First Five PSoC 3 Design eBook provides you with a working foundation. Each project builds upon the knowledge you learn from the previous project. By the time you finish the final project, you will know about the PSoC 3 core, its digital and analog peripherals capabilities
