The USAR ACPITroller
TM
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 ACPI-
compliant 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.
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.
