DESCRIPTION

FEATURES

TM

The LapCoder UR5HCFJ8 is a

versatile, low-power keyboard

encoder for portable systems. The

• Interfaces the Fujitsu FKB7211,

7316, 1406, or other similar

laptop/notebook keyboards to a

• AT / PS/2-compatible

• Implements all functions of a

101/102/104 keyboard with only

82-keys

• Available in DIP, PLCC, and Quad

Flat (QFP) packages

TM

LapCoder provides two bi-

directional channels for

communication with a BIOS-

compatible system as well as any

optional keyboard-compatible

devices, such as a 101/102/104

desktop keyboard.

• Interfaces an external keyboard /

keypad or other 8042-compatible

PIN DESCRIPTIONS

TM

LapCoder handles the scanning,

debounce, and encoding of 82 keys

organized on an 8x16 matrix and

supports embedded numeric

keypad functions as well as

alternate scan codes for specific

keys, so that a keyboard with only

82 keys is able to emulate the

functionality of a 101/102/104

keyboard.

The IC selects 1 of the 16 column

lines (C0-C15) every 512 ms 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. Once the key is

verified, the corresponding key

code(s) are loaded into the transmit

buffer of the PC communication

channel.

Switch Matrix Encoding

Each matrix location is programmed

to represent either a single key or a

key combination of the IBM

101/102/104 standard keyboard.

Scan Code Table Sets

TM

The LapCoder supports all three

scan code table sets. Scan Code

Sets 1 and 2 are the default sets for

AT / PS/2 systems. 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

technical reference manuals.

KEYBOARD ENCODER (CONT’D)

MODE CONTROL

Embedded Numeric Keypad

Operating modes are defined by the logic level of the mode pin in the mode

control unit.

TM

The LapCoder implements an

embedded numeric keypad. The

Numeric Keypad Function is

invoked by pressing the Num Lock

Key.

N-Key Rollover

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

FN Key

corresponding code(s) are transmitted while that key is held pressed. When

the 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 to the

number of keys that can be held pressed at the same time. However, if two

or more key closures occur within a time interval of less than 5 ms, an error

flag is set and those closures are not processed. This protects against the

effects of accidental key presses.

A special FN Key has been

implemented which has the

following effects while it is held

pressed.

For the FKB7211 only:

• Function Key F1 becomes F11

• Function Key F2 becomes F12

• Ctrl Left Key becomes Ctrl Right

• Alt Left Key becomes Alt Right

“Ghost” Keys

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

Status LED indicators

The controller provides interfacing

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). They are set by the

system (AT / PS/2 protocol).

TM

The LapCoder has built-in mechanisms to detect the presence of “ghost”

keys.

IMPLEMENTATION NOTES FOR THE LAPCODER™

The following notes pertain to the suggested schematics found on the next

pages.

TM

The built-in oscillator on the LapCoder requires the attachment of a 4.00

MHz ceramic resonators with built-in load capacitors. You can use either

an AVX part number PBRC-4.00 BR; or a Murata part number

CSTCC4.00MG ceramic resonator.

It may also be possible to operate with the 4.00 MHz crystal, albeit with

reduced performance. Due to their high Q, the crystal oscillator circuits

TM

start-up slowly. Since the LapCoder constantly switches the clock on and

off, it is important that the ceramic resonator is used (it starts up more

quickly 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 either case, using a ceramic resonator with built-in load capacitors, or

crystal with external load capacitors, a feedback resistor of 1 MegaOhm

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).
