Last Updated: 02/08/2013
Version: **
Cypress's USB-to-UART bridge (CY7C64225) controller solution brings plug-and-play USB connectivity to legacy UART peripherals. AN85514 details the implementation of USB-to-RS232 cable using CY7C64225.

Introduction

USB has long been the interface of choice between PCs and their peripherals. However, many legacy PCs still use an RS232 serial interface— in some cases referred to as a UART interface—to communicate with their peripherals.

Cypress’s USB-to-UART Bridge Controller enables seamless connectivity between USB and UART devices. It is a low-power, single-chip, plug-and-play solution that is easy to design and reuses existing application software and firmware—accelerating time to market.
