PC87591E, PC87591S and PC87591L LPC Mobile Embedded Controllers
PRELIMINARY
March 2004
Revision 1.07
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. 鈥淧C87591x鈥?refers to all the devices.
The PC87591x incorporates National鈥檚 CompactRISC
錚?/div>
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

interface, high accuracy analog-to-digital
(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鈥檚 SuperI/O family, the PC87591x
is PC01 and ACPI compliant.
