PC87591E, PC87591S and PC87591L
LPC Mobile Embedded Controllers
General Description
The National Semiconductor PC87591E, PC87591S and
PC87591L are highly integrated, embedded controllers with
an embedded-RISC core and integrated advanced func-
tions. These devices are targeted for a wide range of porta-
ble applications that use the Low Pin Count (LPC) interface.
The PC87591S is targeted for security applications and in-
cludes supporting hardware such as the Hardware Random
Number Generator. The PC8591L replaces the on-chip
flash with 4K of boot ROM for value solutions using shared
BIOS architecture. “PC87591x” refers to all the devices.
The PC87591x incorporates National’s CompactRISC
CR16B core (a high-performance 16-bit RISC processor),
on-chip flash (ROM for the PC87591L) and RAM memories,
system support functions and a Bus Interface Unit (BIU) that
directly interfaces with optional external memory (such as
flash) and I/O devices.
System support functions include: WATCHDOG and other
timers, interrupt control, general-purpose I/O (GPIO) with
internal keyboard matrix scanning, PS/2
ACCESS.bus
(ADC) and digital-to-analog converters (DAC) for battery
charging, system control, system health monitoring and an-
alog controls.

The PC87591x interfaces with the host via an LPC interface
that provides the host with access to the Keyboard and em-
bedded controller interface channels, integrated functions,
Real-Time Clock (RTC), BIOS firmware and security func-
tions.
Like members of National’s SuperI/O family, the PC87591x
is PC01 and ACPI compliant.
