Datasheet

COO (Country of Origin):: US

The 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. The MEC1428 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. The MEC1428 retains eSPI Master Attached Flash (MAF) capability.
