WPC8765L Datasheet | Nuvoton Technology

Description The Nuvoton WPC8765L and WPC8769L are highly integrated embedded controllers (EC) with an embedded RISC core and integrated advanced functions. They are targeted for a wide range of portable applications. The WPC8765L/WPC8769L incorporate the pact RISC® 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 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, and a Sensor Path™ interface. The WPC8765L/WPC8769L interface with the host via an LPC interface.The WPC8765L/WPC8769L are PC01 and ACPI pliant, and offer a single-chip solution for the most monly used notebook PC I/O peripherals. Outstanding Features - Shared BIOS flash memory - Support for SPI flash memories - Flash page programing support - MC-pliant Consumer Infrared (CIR) Port - High-accuracy, high-speed ADC - Up to 88 GPIO ports (including keyboard scanning) with a variety of wake-up events - 16-bit RISC core, with up to 4 Mbytes of external address space, running at up to 25 MHz - 128-pin LQFP package ..
