Revision 1.06

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

Interface,

ACCESS.bus

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’s SuperI/O family, the PC87591x

is PC01 and ACPI compliant.

Outstanding Features

Host interface, based on Intel’s

LPC Interface Speciﬁ-

cation Revision 1.0,

September 29th, 1997

PC01 Rev 1.0, and ACPI 2.0 compliant

16-bit RISC core, with 2 Mbyte address space, and

running at up to 20 MHz

Software and Hardware controlled clock throttling

Shared BIOS ﬂash memory (internal and/or external)

Y2K-compliant RTC

84/117 GPIO ports (for 128-pin/176-pin packages)

with a variety of wake-up events

Extremely low current consumption in Idle mode

JTAG-based debugger interface

128-pin and 176-pin options, in LQFP and CSP pack-

ages (PC87591L is 176-pin only)
