Microchip Technology, Inc. Embedded Controller MEC1310

MEC1310 is a Notebook I/O Controller which incorporates a high-performance 8051- based keyboard and system controller with internal embedded 64KB SRAM, 1Kbyte Boot ROM, and 64- bytes battery backed registers. The embedded 64KB SRAM is loaded via HOST/8051 SPI (Serial Peripheral Interface) Memory Interface. The HOST/8051 SPI Memory Interface can be configured in Switched SPI Flash Configuration or Parallel Shared SPI Flash Configuration. It has two separate power planes to provide “instant on” and system power management functions. Additionally, the MEC1310 incorporates sophisticated power control circuitry (PCC). The PCC supports multiple low power down modes.
