PC87570 Keyboard and Power Management Controller

Highlights

(ACB) Interface, two Multi-Function 16-Bit Timers (MFT16),

periodic interrupt timer and WATCHDOG (TWD), ADC

and DAC.

General Description

The PC87570 is a highly integrated embedded RISC-based

controller optimized for power management (PM), keyboard

and mouse (KBC) and system control in portable Personal

Computer (PC) applications.

The PC87570 highly efficient architecture and its on-chip

peripherals, supporting functions and low power consump-

tion, provide a highly integrated solution for portable note-

book PCs, sub-notebook PCs and other portable devices.

The PC87570 incorporates National’s CompactRISC

CR16A core, a high performance 16-bit RISC processor

core, a Bus Interface Unit (BIU) that directly interfaces with

memory and I/O devices, on-chip memory and system sup-

port functions. Among these are legacy functions, handled

by the Host Bus Interface (HBI), that include the Real-Time

Clock and Advanced Power Control (RTC and APC), and

peripherals, including: frequency-multiplier-based High Fre-

quency Clock Generator (HFCG), Power Mode Control

(PMC), Interrupt Control Unit (ICU), Multi-Input Wake-Up

(MIWU), General Purpose I/O Ports (GPIO) with internal

keyboard matrix scanning, PS/2^®Interface, ACCESS.bus^®

Outstanding Features

●

Shared BIOS memory

●

Fully ACPI-compliant embedded controller

●

Proprietary PS/2 shift mechanism

●

Extremely low current consumption in Idle mode

●

Support for a variety of off-chip wake-up sources

●

Scalable design for growth without controller upgrade
