Description
AI
The
MEC1322 incorporates a high-performance 32-bit embedded microcontroller
with 128 Kilobytes of SRAM and 32 Kilobytes of Boot ROM which communicates
with the system host using the Intel® Low Pin Count (LPC) bus.
The product
has two Serial Peripheral Interface (SPI) memory interfaces that allow the
Embedded Controller (EC) to read its code from external SPI flash memory:
private SPI and/or shared SPI. The Shared SPI interface allows for
Embedded Controller code to be stored in a shared SPI chip along with the
system BIOS. It provides support for loading EC code from the private or
shared SPI flash device on a VCC1 power-on. The MEC1322 is directly
powered by two separates suspend supply planes (VBAT and VCC1) and senses
the runtime power plane (VCC) to provide "Instant On" and system power
management functions.
