MEC140X/MEC141X Family Low-Power Embedded Controllers for Notebook and Tablet PCs Summary The MEC140X/MEC141X family of low-power embedded controllers are customized for notebook and tablet platforms with an eSPI or LPC interface to the host core logic. The MEC140X/MEC141X family is a highly configurable, mixed-signal, advanced I/O controller architecture. Every device in the family incorporates a 32-bit MIPS32 M14K™ microcontroller core with a closely coupled SRAM for code and data. A secure bootloader is used to download your firmware from the system’s shared SPI Flash device, thereby allowing you to customize the device’s behavior. The MEC140X/MEC141X family may be configured to communicate with the system host through one of three host interfaces. The MEC140X devices support two host interfaces: Intel’s Low Pin Count (LPC) and I2C™. The MEC1418 supports three host interfaces: Intel’s new Enhanced Serial Peripheral (eSPI), LPC or I2C. This allows you to manage your product plans and migration from LPC to eSPI with a pin and register compatible embedded controller family. Designers can start today with LPC based designs, easily migrate to eSPI, thereby preserving their investment during their transition to eSPI. The MEC140X/MEC141X family is based on Microchip’s PIC32 architecture and is supported by Microchip’s award winning development tools.
