Keyboard and embedded controllers customized for notebooks and tablets

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.
