87541V

Embedded Controller for Mobile Systems

embedded controller interface channels and to the BIOS

flash.

General Description

The Winbond 87541V is an embedded controller (EC) for

mainstream notebook applications. It contains a highly opti-

mized set of functions, providing a hardware/firmware parti-

tion that enables the implementation of flexible solutions; and

it incorporates the National Semiconductor^®CompactRISC^™

CR16B core (a high-performance 16-bit RISC processor),

which enables the EC functionality to be extended via the

firmware.

Like other members of Winbond’s Advanced I/O family, the

87541V is PC01 and ACPI compliant.

Outstanding Features

■

Host interface, based on Intel’s LPC Interface

Specification Revision 1.1, August 2002

■

PC01 Rev 1.0, and ACPI 2.0 compliant

In addition, the 87541V contains internal ROM and RAM

memories, system support functions and a Bus Interface

Unit (BIU) that directly interfaces with both external memory

(such as flash) and I/O devices.

16-bit RISC core, with 2 Mbytes address space,

running at up to 20 MHz

■

Shared BIOS flash memory (external)

System support functions include: watchdog, PWM, timers,

interrupt control, General-Purpose I/O (GPIO) with internal

keyboard matrix scanning, PS/2^®Interface, SMBus^®inter-

face, and analog-to-digital (ADC) and digital-to-analog

(DAC) converters for battery charging, system monitoring

and analog controls.

88 GPIO ports (including keyboard scanning) with a

variety of wake-up events

■

JTAG-based debugger interface

Software and hardware controlled clock throttling and

extremely low current consumption in Idle mode

The 87541V interfaces with the host via an LPC interface,

which provides the host with access to the Keyboard and
