Microchip Technology MEC1703 Embedded Controller

Microchip Technology MEC1703 Embedded Controller is a highly-configurable, mixed signal, advanced I/O controller customized for notebooks and industrial computing platforms. The MEC1703 incorporates a 32-bit features an Arm® Cortex^®-M4F Microcontroller core with a closely-coupled SRAM for code and data. A secure bootloader is used to download the custom firmware image from the system’s shared SPI Flash device, thereby allowing system designers to customize the device’s behavior.
