DESCRIPTION
FEATURES
The GreenCoder
TM
(UR5HCFJ L) is
a unique, Zero-Power
TM
keyboard
encoder that provides an optimum
performance level for both battery-
operated and desktop systems.
The GreenCoder
TM
scans,
debounces and encodes an 8 X 16
keyboard matrix, and will provide
direct drive for 3 LEDs and two
bi-directional channels for
communication with a BIOS-
compatible system as well as an
additional keyboard-compatible
device. It fully supports all three
PS/2 scan code sets and will
implement up to three alternate
keyboard layers for full 101/102
functionality.
The GreenCoder
TM
employs a
unique Self-Power Management
TM
method that reduces the power
consumption of the keyboard
sub-system to an unprecedented
minimum, transparently and without
user intervention. In “Active” mode,
the encoder consumes less than 2
mA (Typ @5V). In “Sleep” mode the
encoder consumes less than 2 μA
(Typ @5V) The encoder can even
nap between keystrokes and
therefore it is rarely active and
rarely consumes significant levels of
power.
A "stand-by" mode (600 μA Typ
@5V) is entered for as long as
a periodic task is active. After a
programmed period of user
inactivity the GreenCoder
TM
gradually dims the LEDs for
further power savings.
The GreenCoder
TM
is ideal for use in
battery laptop/notebook designs
and Energy Star compliant
keyboards.
