The Nuvoton WPCE775x is a highly integrated family of embedded controllers (EC) with an embedded RISC core and integrated advanced functions. It is targeted for a wide range of portable applications and provides best-in-class complete EC functionality combined with SPI BIOS flash.
The WPCE775x family is pin-to-pin compatible drop-in replacement to the WPC876x family of devices, requiring only minor firmware changes.
All the devices in the WPCE775x family incorporate the CompactRISC® CR16CPlus core (a high-performance 16-bit RISC processor), on-chip ROM and RAM memories, a rich set of system support functions and a high-performance
Flash Interface Unit (FIU) that interfaces directly with external SPI flash memory devices.
System 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, system control, system health monitoring and analog controls.
The WPCE775x family interfaces with the host via an LPC interface. Some WPCE775x devices also include an Integrated SuperI/O with host-controlled Serial Port, Media Center (MC)-compatible CIR Port (WPCE775C and WPCE775F) and a Fast Infrared (FIR, IrDA 1.1 compliant) Port (WPCE775F). The WPCE775x family is PC01 and ACPI compliant.
