MEC1308 is a Notebook I/O Controller which incorporates a high-performance 8051-based keyboard system controller with 64K byte RAM, 1 Kbyte Boot Rom, and 16-bytes battery packed registers.

The 64K RAM is loaded via HOST/8051 SPI Memory Interface, which can be configured in Switched SPI Flash Configuration or Parallel Shared Serial Peripheral Interface (SPI) Flash Configuration. It has four PS/2 ports; a 16C550A-compatible 2-pin UART for Debug Port; a Consumer Infrared Receiver for Vista, two 8584-style I2C/SMBus controllers with two selectable ports per controller; and a Serial IRQ peripheral agent interface. MEC1308 has two separate power planes to provide “instant on” and system power management functions. Additionally, the MEC1308 incorporates sophisticated power control circuitry (PCC).
