Description
The Winbond WPC8768L 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 WPC8768L/WPC8769L incorporate 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 support functions include: watchdog, PWM, timers, interrupt control, General-Purpose I/O (GPIO) with internal keyboard matrix scanning, PS/2® interface, SMBus® interface, UART, SPITM, 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 SensorPathTM interface. The WPC8768L/WPC8769L interface with the host via an LPC interface. They also include a host-controlled Serial Port, CIR Port and Fast Infrared (FIR, IrDA 1.1 compliant) Port (WPC8768L only). The WPC8768L/WPC8769L are PC01 and ACPI compliant, and offer a single-chip solution for the most commonly used notebook PC I/O peripherals.
