MEC1428 Embedded Controller

Microchip Technology MEC1428 Embedded Controller is a highly-configurable, mixed-signal, advanced I/O controller ideal for use in Notebook and Tablet computer applications. The MEC1428 adds a high level of design functionality for computing engineers by adding Slave Attached Flash (SAF), which is an optimal solution for USB Type-C™ power delivery. The MEC1428 Controller is pin and register compatible with the MEC140X and MEC141X Controller families, allowing designers to add eSPI and additional features and increase design flexibility. The MEC1428 retains eSPI Master Attached Flash (MAF) capability.
