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.
