UR8HC342

The USAR ACPITrollerTM 342 R8HC342 is a single IC thatfunctions both as an 8042-typeHuman 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 UR8HC342 achieves unparalleled minimum power consumption (typically less than 1A) due to USAR's patented Zero-Power™ technologies for both PS/2 portsand the SMBus port - an industry first. The USAR ACPITroller™ 342 can power down even when devices are connected and active. Based on USAR's patented Zero- Power™ technology, the
UR8HC342 always operates in the "STOP" mode, independently of the configuration and without any data or event losses.

Using the UR8HC342, system designers can implement systems that take advantage of the SMBus, the Smart Battery System, and the ACPI specifications, all using a single IC. The UR8HC342 can be customized easily through an extensive library of hardware and firmware modules in order to accommodate specialized configurations at low production cost.
