Computing MEC14XX Family Low-Power Embedded Controllers for Computing Applications Modernize Your Computing Platforms As Intel Processors fully transition towards the more flexible and efficient eSPI host interface, computing products must progress along with it. The MEC14XX family of devices provides low-power, highly configurable embedded controllers for an effortless transition. Microchip offers a flexible array of solutions for all mobile platforms includ - ing notebooks, tablets, SBCs and industrial controllers. All MEC14XX devices are pin compatible with each other to provide easy migration from LPC-based to eSPI-based designs.
