MEC1428-NU-C1 isthe latest member of the MEC14XX family and adds a new level of designfunctionality for computing engineers by adding Slave Attached Flash (SAF),which is an optimal solution for USB Type-C™ power delivery. This device is pinand register compatible with the MEC140X and MEC141X families, which allowsdesigners to easily add eSPI and additional features and have more flexibilityin their designs. It retains eSPI Master Attached Flash (MAF) capability.
The MEC14xx family is a keyboard and embedded controllercustomized for notebooks and computing platforms. The MEC140X/1X/2X family is ahighly-configurable, mixed signal, advanced I/O controller architecture.MEC1428-NU-C1 incorporates a 32-bit MIPS32 M14K Microcontroller core with 192 KB ofclosely-coupled SRAM for code and data that loads from SPI Flash. Designers canleverage the host SPI-flash (used for BIOS storage) for non-volatile ECfirmware storage, as a cost-effective system solution. Microchip’s MEC14XX family also provides a flexible arrangement that allowsmultiple I/O signals to be configured to support either 3.3V or 1.8V, reducingthe system bill-of-materials cost by eliminating the need for external voltagetranslators. The MEC1428-NU-C1 communicates with the system host through the IntelEnhanced Serial Peripheral Interface (eSPI) or through Intel's Low Pin Count(LPC). All members of the MEC14XX family are pin and register compatible and aresupported by Microchip’s development tools. Examples include the MPLAB® XCCompilers, the MPLAB REAL ICE™ In-Circuit Emulator (part #DV244005), the MPLAB ICD 3 In-Circuit Debugger (part # DV164035) and the PICkit™ 3Starter Kit (part # DV164130).
