MEC1404-NU The MEC140X/1X family is a highly-configurable, mixed signal, advanced I/O controller architecture. MEC1404 is a keyboard and embedded controller customized for notebooks and tablet platforms. As a cost-effective system solution, it incorporates a 32-bit MIPS32 M14K Microcontroller core with 128KB 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. Microchip?s MEC14XX family reduces the system bill-of-materials cost by providing a flexible arrangement that allows multiple I/O signals to be configured to support either 3.3V or 1.8V. This eliminates the need for external voltage translators The MEC1406 communicates with the system host through Intel Low Pin Count (LPC) or I2C. 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), MPLAB ICD 3 In-Circuit Debugger (part # DV164035) and PICkit? 3 Starter Kit (part # DV164130).

Designers can leverage the host SPI-flash (used for BIOS storage) for non-volatile EC firmware storage. Microchip?s MEC14XX family reduces the system bill-of-materials cost by providing a flexible arrangement that allows multiple I/O signals to be configured to support either 3.3V or 1.8V. This eliminates the need for external voltage translators The MEC1406 communicates with the system host through Intel Low Pin Count (LPC) or I2C. 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), MPLAB ICD 3 In-Circuit Debugger (part # DV164035) and PICkit? 3 Starter Kit (part # DV164130).
