Microchip CEC1302低功耗加密嵌入控制器方案
Microchip公司的CEC1302是集成了高性能32位ARM® Cortex®-M4嵌入MCU和128KB SRAM和32KB引导ROM的低功耗加密嵌入控制器,通信采用I2C总线.器件的两个SPI存储器接口允许EC从外接SPI闪存储器读取代码.本文介绍了CEC1302主要特性,框图,评估板Clicker 2主要特性和电路图.
The CEC1302 incorporates a high-performance 32-bitARM® Cortex®-M4 embedded microcontroller with 128Kilobytes of SRAM and 32 Kilobytes of Boot ROM. Itcommunicates with the system host using the I2C bus.
The CEC1302 has two SPI memory interfaces thatallow the EC to read its code from external SPI flashmemory: private SPI and/or shared SPI. The SharedSPI interface allows for EC code to be stored in ashared SPI chip. The private SPI memory interface providesfor a dedicated SPI flash that is only accessibleby the EC.
