cypress公司的EZ-PD™ CCG2是具有最新的USB Type-C和PD标准的USB Type-C控制器,为无源电缆,有源电缆和电源附件提供完整的USB Type-C和USB PD端口控制解决方案.器件采用M0S8技术,集成了32位48MHz ARM® Cortex®-M0处理器和32KB闪存,完整的Type-C收发器以及Type-C端电阻RP, RD和 RA主要用在USB Type-C EMCA电缆,电源附件,上行方向端口和下行方向端口.本文介绍了EZ-PD™ CCG2主要特性,逻辑框图,系统框图和多种应用框图,以及CCG2 24W电原适配器(PA)评估板主要指标,电路图,材料清单.

EZ-PD™ CCG2 is a USB Type-C controller that complies with the latest USB Type-C and PD standards. EZ-PD CCG2 provides a complete USB Type-C and USB Power Delivery port control solution for passive cables, active cables, and powered accessories. It can also be used in many upstream and downstream facing port applications. EZ-PD CCG2 uses Cypress’s proprietary M0S8 technology with a 32-bit, 48-MHz ARM® Cortex®-M0 processor with 32-KB flash and integrates a complete Type-C Transceiver including the Type-C termination resistors RP, RD and RA.

EZ-PD™ CCG2主要特性:

32-bit MCU Subsystem
■ 48-MHz ARM Cortex-M0 CPU
■ 32-KB Flash
■ 4-KB SRAM
■ In-system reprogrammable
Integrated Digital Blocks
■ Integrated timers and counters to meet response timesrequired by the USB-PD protocol
■ Run-time reconfigurable serial communication block (SCB)with reconfigurable I2C, SPI, or UART functionality
Clocks and Oscillators
■ Integrated oscillator eliminating the need for external clock
Type-C Support
■ Integrated transceiver (baseband PHY)
■ Integrated UFP (RD), EMCA (RA) termination resistors, andcurrent sources for DFP (RP)

■ Two independent VCONN rails with integrated isolationbetween the two
■ Independent supply voltage pin for GPIO that allows 1.71-V to5.5-V signaling on the I/Os
■ Reset: 1.0 μA, Deep Sleep: 2.5 μA, Sleep: 2.0 mA
System-Level ESD on CC and VCONN Pins
■ ± 8-kV Contact Discharge and ±15-kV Air Gap Discharge basedon IEC61000-4-2 level 4C
Packages
■ 1.63 mm × 2.03 mm, 20-ball wafer-level CSP (WLCSP) with0.4-mm ball pitch
■ 2.5 mm × 3.5 mm × 0.6 mm 14-pin DFN
■ 4.0 mm × 4.0 mm, 0.55 mm 24-pin QFN
■ Supports industrial (-40℃ to +85℃) and extended industrial(-40 ℃ to +105 ℃) temperature ranges
Applications
■ USB Type-C EMCA cables
■ USB Type-C powered accessories
■ USB Type-C upstream facing ports
■ USB Type-C downstream facing ports

CCG2 24W电原适配器(PA)评估板

The CCG2 24W Power Adapter (PA) Board is receptacle based Type-C power adapter which supports outputs of 5V@3A, 9V@2.7A and 12V@2A. The major components on the board are Cypress’s EZ-PD CCG2 (CYPD2134-24LQXIT) controller and Dialog Semiconductor’s iW1782-00 AC-DC controller and iW671-00 Sync Rectifier.
