UR5HCFJL

The GreenCoderTM (UR5HCFJL) is a unique, Zero-PowerTM keyboard encoder that provides an optimum performance level for both batteryoperated and desktop systems.

The GreenCoderTM UR5HCFJL 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 BIOScompatible system as well as an additional keyboard-compatible device. UR5HCFJL fully supports all three PS/2 scan code sets and will implement up to three alternate keyboard layers for full 101/102 functionality.

The GreenCoderTM UR5HCFJL 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 A (Typ @5V) The encoder can even nap between keystrokes and therefore UR5HCFJL is rarely active and rarely consumes significant levels of power.

UR5HCFJL A "stand-by" mode (600 A 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.

The GreenCoderTM UR5HCFJL is ideal for use in battery laptop/notebook designs and Energy Star compliant keyboards.
