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-pliant 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 ACPIpliant 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...
