MEC1322-NU Product Details

TheMEC1322-NU 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-NU 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.
