The MEC1635 is the mixed signal base component of a multi-device advanced I/O controller architecture, which incorporates a high-performance 32-bit ARC 625D embedded microcontroller with a 192KB Embedded Flash Subsystem, 16KB of SRAM and a 1KB EEPROM Emulation. The MEC1635 communicates with the system host using the Intel® Low Pin Count bus.

This product is the Embedded Controller Base Component of a split-architecture Advanced I/O Controller system that uses BC-LinkTM communication protocol to access up to three companion components. MEC1635 is directly powered by two separate suspend supply planes (VBAT and VTR) and senses a third runtime power plane (VCC) to provide “instant on” and system power management functions. Integrated VTR Reset Interface and a system Power Management Interface that supports low-power states and can drive state changes as a result of hardware wake events as defined by the MEC1635 Wake Interface included.
