Zero-PowerTM Keyboard  
Encoder for Portable Systems  
HID & S YS TEM MANAGEMENT P RODUCTS , KEYCODERTM FAMILY  
DESCRIPTION  
FEATURES  
The GreenCoderTM (UR5HCFJL) is  
a unique, Zero-PowerTM keyboard  
encoder that provides an optimum  
performance level for both battery-  
operated and desktop systems.  
• Optimized power-saving operation  
with idle consumption of less  
than 2 µA  
• Programmable LED dimming for  
further power savings  
• 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  
• Ready to interface to Fujitsu's  
7316, 7654,7656, and  
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  
1406 keyboards  
• 3, 3.3 and 5 Volt operation  
• Custom versions available in small  
or large quantities  
APPLICATIONS  
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.  
• 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.
