Description
AI
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.
