Status: In Production
MEC1428 is the latest member of the MEC14XX family and adds a new level of design functionality for computing engineers by adding Slave Attached Flash (SAF), which is an optimal solution for USB Type-C™ power delivery. This device is pin and register compatible with the MEC140X and MEC141X families, which allows designers to easily add eSPI and additional features and have more flexibility in their designs. It retains eSPI Master Attached Flash (MAF) capability.
The MEC14xx family is a keyboard and embedded controller
customized for notebooks and computing platforms. The MEC140X/1X/2X family is a
highly-configurable, mixed signal, advanced I/O controller architecture.
MEC1428 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 MEC1428 communicates with the system host through the Intel
Enhanced Serial Peripheral Interface (eSPI) or through Intel's 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).
