Nuvoton WPCE775, a highly integrated embedded controller (EC) with an embedded RISC core and integrated advanced functions, targets an extensive market of portable applications and provides best-in-class complete EC functionality when combined with SPI BIOS Flash. WPCE775 incorporates the CompactRISC® CR16CPlus core (a high-performance 16-bit RISC processor), on-chip ROM and RAM memories, system support functions, and a Flash Interface Unit (FIU) that interfaces directly with external SPI flash memory devices.

System of WPCE775 support functions include: Watchdog, PWM, Timers, Interrupt Control, General-Purpose I/O (GPIO) with internal keyboard matrix scanning, PS/2® interface, SMBus® interface, UART, SPI ™ , High-accuracy analog-to-digital (ADC) and Digital-to-analog (DAC) converters for battery charging. WPCE775 also has System control, system health monitoring, and analog controls.

WPCE775 interfaces with the host via an LPC interface which includes a host-controlled Serial Port. It conforms to Media Center Edition (MCE) compatible CIR Port, a high speed Infrared (FIR, IrDA 1.1 compliant) Port, and PC01 & ACP.
