UR8HC342-FQ - 342 Robust 8042 Keyboard / ACPI-Embedded Controller

Datasheet Summary

Description

The USAR ACPITrollerTM 342 UR8HC342 is a single IC that functions both as an 8042-type Human Input Device Controller (HIDC) and an ACPI-compliant Embedded Controller (EC).

The UR8HC342 provides the typical functionality of an 8042-type HID Controller with embedded key and motion scanning.

Features

Acts as an 8042 HID and ACPI Embedded Controller.
Typically consumes less than 1µA.
Two external PS/2 ports for external keyboard and mouse with autodetect and hot-plug support.
Patented Zero-Power™ operation of all PS/2 ports and the SMBus port an industry first.
Simultaneous operation of external and internal input devices.
AlphaMouseTM Pointing Devices Manager provides Mousewheel support- a first for an EC.
Acts as a keyboard con.

USAR ACPITrollerTM 342 UR8HC342 USAR ACPITrollerTM 342 Robust 8042 Keyboard / ACPI-Embedded Controller Description The USAR ACPITrollerTM 342 UR8HC342 is a single IC that functions both as an 8042-type Human Input Device Controller (HIDC) and an ACPI-compliant Embedded Controller (EC). The UR8HC342 provides the typical functionality of an 8042-type HID Controller with embedded key and motion scanning. In addition, the UR8HC342 functions as an ACPIcompliant Embedded Controller (EC) and SMBus host. The IC achieves unparalleled minimum power consumption (typically less than 1µA) due to USAR's patented Zero-Power™ technologies for both PS/2 ports and the SMBus port - an industry first. The USAR ACPITroller™ 342 can power down even when devices are connected and active.
