Revision 1.0

WPC8768L, WPC8769L Mobile Embedded Controller with

SPI

Flash Interface and MCE-Compliant CIR Port

General Description

The Winbond WPC8768L and WPC8769L are highly inte-

grated 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 proces-

sor), on-chip ROM and RAM memories, system support

functions and a Flash Interface Unit (FIU) that interfaces di-

rectly 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® inter-

face, UART, SPI™, high-accuracy analog-to-digital (ADC)

and digital-to-analog (DAC) converters for battery charging,

system control, system health monitoring and analog con-

trols, and a SensorPath™ 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.
