The MEC140X/1X family is a highly-configurable, mixed signal,advanced I/O controller architecture. MEC1418-I/NU is a keyboard and embeddedcontroller customized for notebooks and tablet platforms. It incorporates a32-bit MIPS32 M14K Microcontroller core with 192KB of closely-coupled SRAM forcode and data that loads from SPI Flash. Designers can leverage the hostSPI-flash (used for BIOS storage) for non-volatile EC firmware storage, as acost-effective system solution. Microchip’s MEC14XX family reduces the system bill-of-materials cost byproviding a flexible arrangement that allows multiple I/O signals to beconfigured to support either 3.3V or 1.8V. This eliminates the need forexternal voltage translators. The MEC1418communicates with the system host through the Intel Enhanced Serial PeripheralInterface (eSPI) or through Intel's Low Pin Count (LPC). All members of the MEC14XX family are pin andregister compatible and are supported by Microchip’s development tools.Examples include the MPLAB® XC Compilers, the MPLAB REAL ICE™ In-CircuitEmulator (part # DV244005), the MPLAB ICD 3 In-Circuit Debugger (part #DV164035) and the PICkit™ 3 Starter Kit (part # DV164130).
