Microchip Technology CEC1302 低功耗加密嵌入式控制器
Microchip CEC1302 低功耗加密嵌入式控制器采用一个 32 位 ARM® Cortex®-M4 嵌入式微控制器。 CEC1302 拥有 128KB SRAM、32KB 启动 ROM 和 I2C 总线，可与系统主机进行通信。 两个 SPI 存储器接口允许 EC 从外部 SPI 闪存（私有 SPI和/或共享 SPI）读取其代码。 共享 SPI 接口允许在共享 SPI 芯片中存储 EC 代码。 私有 SPI 存储器接口提供一个只有 EC 能够访问的专用 SPI 闪存。
Two SPI memory interfaces allow the EC to read its code from external SPI flash memory: private SPI and/or shared SPI. The Shared SPI interface allows for EC code to be stored in a shared SPI chip. The private SPI memory interface provides for a dedicated SPI flash that is only accessible by the EC.
