See FIGURE 1: MEC1310 Block Diagram on page 4. The MEC1310 incorporates a high-performance 8051based keyboard and system controller with internal embedded 64K SRAM; a 1K byte Boot ROM, and 64bytes 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 wakeup 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. - Channel 0 has a 5 volt tolerant input - Optional continuous sampling at a programmable rate - Selectable VREF source on a per Channel Basis – VREF pin or AVCC • 128-Pin VTQFP RoHS Compliant Package DS00001768A-page 2 2014 Microchip Technology Inc.

Most Current Data Sheet To obtain the most up-to-date version of this data sheet, please register at our Worldwide Web site at: http://www.microchip.com You can determine the version of a data sheet by examining its literature number found on the bottom outside corner of any page. The last character of the literature number is the version number, (e.g., DS30000000A is version A of document DS30000000). Errata An errata sheet, describing minor operational differences from the data sheet and recommended workarounds, may exist for current devices. As device/documentation issues become known to us, we will publish an errata sheet. The errata will specify the revision of silicon and revision of document to which it applies. To determine if an errata sheet exists for a particular device, please check with one of the following: • Microchip’s Worldwide Web site; http://www.microchip.com • Your local Microchip sales office (see last page) When contacting a sales office, please specify which device, revision of silicon and data sheet (include -literature number) you are using.
