Cypress CY4541 EZ－PD CCG4双路USB Type－C开发方案

Cypress公司的CY4541 EZ-PD™ CCG4是具有最新USB Type C和PD标准的双路USB Type-C控制器,为笔记本电脑,电源适配器和坞站提供完整的双路USB Type-C和USB电源提供端口控制解决方案.采用Cypress的M0S8技术和32位48MHz 48-MHz ARM® Cortex®-M0处理器以及128KB闪存储器,并集成了两个完整的Type-C收发器及其端电阻RP和RD.本文介绍了EZ-PD™ CCG4主要特性,逻辑框图,功能框图,USB-PD子系统框图以及几种应用电路图,评估板(EVK)基板和子板框图,主要特性和电路图与材料清单.
EZ-PD™ CCG4 is a dual USB Type-C controller that complies with the latest USB Type-C and PD standards. EZ-PD CCG4 providesa complete dual USB Type-C and USB-Power Delivery port control solution for notebooks, power adapters and docking stations. Itcan also be used in dual role and downstream facing port applications. EZ-PD CCG4 uses Cypress’s proprietary M0S8 technologywith a 32-bit, 48-MHz ARM® Cortex®-M0 processor with 128 KB flash and integrates two complete Type-C Transceivers including theType-C termination resistors RP and RD.
