CYW20819/CYW20820 Hardware Design Guide

This document provides hardware layout design guidelines for the CYW20819/CYW20820. This document covers basic layout guidelines which include the board stack-up and the impedance control requirements, component placements and recommended parts for the critical components and routing guidelines and the recommended trace width for various power traces. This document must be referred while designing any board to leverage the CYW20819/CYW20820 silicon.


CYW920820EVB-02 Evaluation Kit

The Cypress CYW920820EVB-02 Evaluation Kit enables you to evaluate and develop applications using the CYW20820. The CYW20820EVB-02 is an Arduino compatible evaluation that features a 62-ball CYW20820 device, an on-board programmer, two user LEDs and a switch and on-board sensors such as a thermistor and a 9-axis motion sensor. The kit webpage provides more details on this kit and hosts resources such as kit quick start guide, user guide and hardware design files. 


The CYW920820EVB-02 Evaluation Kit will be available soon from a Cypress distributor. Contact Cypress sales for availability.
