WPC8765L
SPI
(Revisions A4 and A5)
General Description
The Nuvoton WPC8765L 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 WPC8765L/WPC8769L incorporate the CompactRISC
CR16CPlus core (a high-performance 16-bit RISC proces-
sor), on-chip ROM and RAM memories, system support func-
tions 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
face, UART, SPI
and digital-to-analog (DAC) converters for battery charging,
system control, system health monitoring and analog con-
trols, and a SensorPath
The WPC8765L/WPC8769L interface with the host via an
LPC interface.The WPC8765L/WPC8769L are PC01 and
ACPI compliant, and offer a single-chip solution for the most
commonly used notebook PC I/O peripherals.
