GreenCoderTM UR5HCFJL
Zero-PowerTM Keyboard
Encoder for Portable Systems
HID & SYSTEM MANAGEMENT PRODUCTS, KEYCODERTM FAMILY
DESCRIPTION
The GreenCoderTM (UR5HCFJL) is
a unique, Zero-PowerTM keyboard
encoder that provides an optimum
performance level for both battery-
operated and desktop systems.
The GreenCoderTM 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.
FEATURES
Optimized power-saving operation
with idle consumption of less
than 2 µA
Programmable LED dimming for
further power savings
Ready to interface to Fujitsu's
7316, 7654,7656, and
1406 keyboards
3, 3.3 and 5 Volt operation
Wakes-up only to respond to an
external event and for a minimum
period of time (2 mA current
consumption)
Provides interface for external
keyboard/keypad or other 8042-
compatible device
Custom versions available in small
or large quantities
APPLICATIONS
Laptop/Notebook
Portable Equipment
Energy Star Compliant
Medical Instruments
Palmtops/ PDAs
PIN ASSIGNMENTS
The GreenCoderTM employs a
unique Self-Power ManagementTM
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 GreenCoderTM
gradually dims the LEDs for
further power savings.
