MEC1322中文资料Embedded Controller数据手册Microchip规格书

描述 Description

TheMEC1322 incorporates a high-performance 32-bit embedded microcontrollerwith 128 Kilobytes of SRAM and 32 Kilobytes of Boot ROM which communicateswith the system host using the Intel® Low Pin Count (LPC) bus. The producthas two Serial Peripheral Interface (SPI) memory interfaces that allow theEmbedded Controller (EC) to read its code from external SPI flash memory:private SPI and/or shared SPI. The Shared SPI interface allows forEmbedded Controller code to be stored in a shared SPI chip along with thesystem BIOS. It provides support for loading EC code from the private orshared SPI flash device on a VCC1 power-on. The MEC1322 is directlypowered by two separates suspend supply planes (VBAT and VCC1) and sensesthe runtime power plane (VCC) to provide “Instant On” and system powermanagement functions. Family partsMEC1322I-NU-C0MEC1322-LZYMEC1322-LZY-C0MEC1322-LZY-C0-TRMEC1322-NUMEC1322-NU-C0MEC1322-SZ-C0MEC1322-SZ-C0-TR
