Customized for notebooks and tablet platforms, Microchip's MEC140x/1x
keyboard and embedded controllers are now available from Mouser stock.
The highly-configurable mixed-signal devices include an advanced I/O
controller architecture. Each device incorporates a 32-bit MIPS32R M14KT
Microcontroller core with 128KB of closely-coupled SRAM for code and data
that loads from SPI Flash. Designers can leverage the host SPI-flash (used
for BIOS storage) for non-volatile EC firmware storage, as a cost-effective
system solution. These also provide a flexible arrangement that allows
multiple I/O signals to be configured to support either 3.3V or 1.8V. This
reduces the system bill-of-materials cost by eliminating the need for
external voltage translators. The MEC1404 communicates with the system host
through Intel Low Pin Count (LPC) or I2C.
