WPC8768L, WPC8769L Mobile Embedded Controller with
SPI^TM 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.
