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.

The encoder scans a keyboard
organized as an 8 row by 16 column
matrix for a maximum of 128 keys.
Smaller-size keyboards are support-
ed provided that all unused row
lines are pulled to Vcc. When
active, the encoder selects 1 of the
16 column lines (C0-C15) every 512
µS and then reads the row data
lines (R0-R7). A key closure is
detected as a 0 in the
corresponding position of the matrix.
A complete scan cycle for the entire
keyboard takes approximately 9.2
mS. Each key found pressed is
debounced for a period of 20 mS.

Scan Code Table Sets
The UR5HCFJL supports all three
scan code table sets. Scan Code
Table Set 3 allows the user to
program individual key attributes
such as Make/Break and Typematic
or Single-Touch Action. For more
information, refer to the IBM Tech-
nical Reference Manuals. Custom
scan code tables, including macros,
are also available.

KEYBOARD ENCODER, (CON’T)
MODE CONTROL
Em b e d d e d Nu m e ric Ke yp a d
N-Ke y Ro llo ve r
The GreenCoderTM implements an
embedded numeric keypad. The
Numeric Keypad Function is
invoked by pressing the Num Lock
Key.
In this mode, the code(s) corresponding to each key press are transmitted
to the host system as soon as that key is debounced, independently of the
release of other keys.
If a key is defined to be Typematic, the corresponding make code(s) will be
transmitted while the key is held pressed. When a key is released, the
corresponding break code(s) are then transmitted to the host system. If the
released key happens to be the most recently pressed, then Typematic
action is terminated. There is no limitation in the number of keys that can
be held pressed at the same time. However, two or more key closures,
occurring within a time interval less than 5 mS, will set an error flag and will
not be processed. This procedure protects against effects of accidental key
presses.
FN Ke y
A special FN Key has been
implemented to perform the
following functions while it is held
pressed:
• Function Key F1 becomes F11
• Function Key F2 becomes F12
“Gh o s t ” Ke ys
In any scanned contact switch matrix, whenever three keys defining a
rectangle on the switch matrix are held pressed at the same time, a fourth
key positioned on the fourth corner of the rectangle is sensed as being
pressed. This is known as the “ghost” or “phantom” key problem. Although
the problem cannot be totally eliminated without using external hardware,
there are methods to neutralize its negative effects for most practical
applications. Keys that are intended to
• Control Left Key becomes Ctrl
Right
• Embedded numeric keypad keys
become regular keys
If Num Lock is not set:
• Embedded numeric keypad keys
provide the same codes as a
numeric keypad when the Num

PgDn, etc.)
Actual key presses
be used in combinations or are likely to
be pressed at the same time by a fast
typist (i.e., keys located in adjacent
positions on the keyboard) should be
placed in the same row or column of the
matrix whenever possible. Shift Keys
(Shift, Alt, Ctrl) should not reside in the
same row (or column) with any other
keys. The GreenCoderTM has built-in
mechanisms to detect the presence of a
“ghost” key, thus eliminating the
“Ghost”
Key
S t a t u s LED in d ic a t o rs
The controller provides an interface
for three LED shift status indicators.
All three pins are active low to
indicate the status of the host
system (Num Lock, Caps Lock and
Scroll Lock) and are set by the
system. After approximately a one-
minute period of keyboard inactivity,
LEDs are dimmed to conserve
power. They are set to full

8042 EMULATION CHANNEL
SPECIAL HANDLING
The GreenCoderTM fully emulates a
system’s keyboard port, available to
a standard 84/85/101/102 external
keyboard or other 8042-compatible
device. Communication with a
keyboard-compatible device is
accomplished by clock and data
lines via EKC and EKD pins,
respectively. A third pin, EKC1 that
connects to the Clock Line,
interrupts the controller whenever
the external device initiates a
communication session.
Co n n e c t io n o f Ex t e rn a l De vic e
The UR5HCFJL will detect the presence of an external device. If an
external keyboard or other device was not connected during power-on and
is connected at a later time, the encoder will proceed with the normal reset
routine in order to properly initialize the external device. After
communication has been established, the encoder will continue to check for
the presence of the external device. While the external device is
connected, the encoder will not enter the sleep mode. If the device is
disconnected at a later time, the encoder will become aware of it. If a
subsequent connection takes place, the controller will re-initiate a reset
sequence. This unique feature allows the user to connect or disconnect an
external device at any time without having to reset the system.
S h ift S t a t u s LEDs
When power is first applied, the
controller proceeds with the
standard reset sequence with the
external device. Data and
Shift Status LEDs (Num Lock, Caps Lock and Scroll Lock) indicate the
status of the system and are controlled by commands sent from the system.
Set/Reset Status Indicator Commands from the system will be executed
both by the external keyboard and the scanned matrix.
For example, if the user presses the Caps Lock Key on either keyboard, the
Caps Lock LED will be affected on both keyboards. The LED status
indicators are properly set after each new connection of an external
keyboard.
commands initiated from the
external device are buffered in the
controller’s FIFO along with data
from the scanned matrix, and then
are presented to the system as if
they were coming from a single
source. Once they are
acknowledged, commands and
data from the system are then
transmitted to the external device.

STATES OF OPERATION
USING THE GREENCODERTM FOR SYSTEM MANAGEMENT TASKS
The GreenCoderTM has three states
of operation, implemented to
minimize the power consumption of
the keyboard subsystem. The
following diagram illustrates the
three states of operation of the
GreenCoderTM.
The GreenCoderTM provides an ideal complement to low-power chip sets
targeted to the portable and mobile computing market. The GreenCoderTM
can be used to handle several system management tasks for small, portable
system designs, thus saving space and additional components for the
System Designer. Such system management tasks include those listed
below.
However, since most of the system management tasks are application and
hardware-dependent, detailed implementation information is outside the
scope of this document. For application examples and sample schematics,
contact Semtech Technical Support.

STATE
The GreenCoderTM can provide the system power management unit with a
shut-down/wake-up signal which can be invoked either by a special
keyboard combination or after a programmed period of user inactivity.
Fig u re 2 : States of Operation of
UR5HCFJL
No t e : Self-Power ManagementTM is a feature protected under Semtech Corp. patent and copyright rights.
Purchase of any version of the UR5HCFJL encoder conveys a license to utilize the Self-Power Management
feature only through use of the UR5HCFJL in a PS/2-compatible keyboard subsystem.
Most of the time, the GreenCoderTM
is in the Sleep State. Power
consumption in this state is
approximately 2 µA at 5 Volts of
operation. The GreenCoderTM enters
the Active State only when there is
an event to process, such as a
keystroke, a command from the
system, or data from the external
PS/2-compatible device.
The GreenCoderTM enters and stays
in the Stand-By State if an external
device is connected to the auxiliary
port or if one or more LEDs are
turned on.
In the Stand-By State, the IC
consumes approximately 600 µA at
5 Volts. Transition from one state to
the other does not require any input
from the system.

IMPLEMENTATION NOTES FOR THE UR5HCFJL
The following notes pertain to the suggested schematics found on the next
pages.
The Built-in Oscillator on the UR5HCFJL requires the attachment of the 4.00
MHz Ceramic Resonators with built-in Load Capacitors.. You can use either
an AVX, part number PBRC-1.00 BR; or a Murata part number
CSTCC2.00MG ceramic resonator.
It may also be possible to operate with the 2.00 MHz Crystal, albeit with
reduced performance. Due to their high Q, the Crystal oscillator circuits
start-up slowly. Since the GreenCoderTM constantly switches the clock on
and off, it is important that the Ceramic Resonator is used (it starts up much
quicker than the Crystal). Resonators are also less expensive than Crystals.
Also, if Crystal is attached, two Load Capacitors (33pF to 47pF) should be
added, a Capacitor between each side of the Crystal and ground.
In both cases, using Ceramic Resonator with built-in Load Capacitors, or
Crystal with external Load Capacitors, a feedback Resistor of 1 Meg should
be connected between OSCin and OSCout.
Troubleshoot the circuit by looking at the Output pin of the Oscillator. If the
voltage it half-way between Supply and Ground (while the Oscillator should
be running) --- the problem is with the Load Caps / Crystal. If the voltage it
all the way at Supply or Ground (while the Oscillator should be running) ---
there are shorts on the PCB.
NOTE: when the Oscillator is intentionally turned OFF, the voltage on the
Output pin of the Oscillator is High (at the Supply rail).
