MEC1310-NU-TR

The MEC1310 is a 128-pin 3.3V LPC-based ACPI 2.0 and PC99/PC2001 compliant Notebook I/O Controller. The MEC1310 incorporates a high-performance 8051-based keyboard and system controller with internal embedded 64K SRAM, a 1K byte Boot ROM, and 64-bytes battery backed registers. The embedded 64K SRAM is loaded via HOST/8051 SPI Memory Interface. The HOST/8051 SPI Memory Interface can be configured in Switched SPI Flash Configuration or Parallel Shared SPI Flash Configuration. The MEC1310 has four PS/2 ports; an 16C550A-compatible 2 pin UART for Debug Port; three 8584-style I2C/SMBus controllers with two selectable ports per controller; a Serial IRQ peripheral agent interface; three ACPI Embedded Controller Interface; General Purpose I/O pins and seven General Purpose Outputs; four independently programmable pulse width modulators; dual fan control through the implementation of two fan tachometer input pins, RPM-PWM block with one tachometer input and one PWM output; hardware monitoring of a PWM input and maskable hardware wake-up events; one BC-Link Combined High Speed/Low Speed Bus Master Controller; 5 channel Analog to Digital Converter. The MEC1310 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. Wake-up events and ACPI-related functions are supported through the SCI Interface. The MEC1310 supports the ISA Plug-and-Play Standard (Version 1.0a) and provides all the functionality for current Windows O/S's. The I/O Address and Hardware IRQ of each logical device in the MEC1310 may be reprogrammed through the internal configuration registers. There are 480 I/O address location options and 15 IRQs for each logical device.
