MEC140X/1X - Keyboard and Embedded Controller Products for Notebook PC (06/29/2015)

Please consider this device:  MEC1404, MEC1406, MEC1408.   View Side By Side Comparison
The MEC1418 is a keyboard and embedded controller customized for notebooks and tablet platforms. The MEC140X/1X family is a highly-configurable, mixed signal, advanced I/O controller architecture. MEC1418 incorporates a 32-bit MIPS32 M14K Microcontroller core with 192 KB of closely-coupled SRAM for code and data that loads from SPI Flash. Designers can leverage the host SPI-flash (used for BIOS storage) for non-volatile EC firmware storage, as a cost-effective system solution.

Microchip’s MEC14XX family also provides a flexible arrangement that allows multiple I/O signals to be configured to support either 3.3V or 1.8V, reducing the system bill-of-materials cost by eliminating the need for external voltage translators. The MEC1418 communicates with the system host through the Enhanced Serial Peripheral Interface (eSPI) or through Low Pin Count (LPC).

All members of the MEC14XX family are pin and register compatible and are supported by Microchip’s development tools. Examples include the MPLAB® XC Compilers, the MPLAB REAL ICE™ In-Circuit Emulator (part # DV244005), the MPLAB ICD 3 In-Circuit Debugger (part # DV164035) and the PICkit™ 3 Starter Kit (part # DV164130).
