The MEC1308 is a 128-pin, 3.3V LPC-based embedded controller designed for notebook PCs, compliant with ACPI 2.0 and PC99/PC2001 standards. It features a high-performance 8051-based keyboard and system controller, equipped with 64KB of internal SRAM and a 1KB Boot ROM. The device supports a HOST/8051 SPI Memory Interface, allowing for flexible configurations with either Switched or Parallel Shared SPI Flash. This controller includes four PS/2 ports, a 16C550A-compatible UART for debugging, and two I2C/SMBus controllers, each with selectable ports. It also provides 48 general-purpose I/O pins, seven additional general-purpose outputs, and four independent pulse-width modulator outputs. The MEC1308 is designed for efficient power management, featuring two power planes and multiple low-power modes, making it suitable for applications requiring quick wake-up capabilities and system monitoring. With integrated features such as a consumer infrared receiver, dual fan tachometer inputs, and a general-purpose analog-to-digital converter, the MEC1308 offers a comprehensive solution for notebook I/O control and system management.
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).
