USAR SerialCoder

Low-Power Keyboard Encoder

interfaces RS-232

USAR KeyCoder family

product specifications

Description

Features

The USAR SerialCoder

• 8 x 16 Matrix Encoding

• 9600 Baud 8N1Serial Data Format

• IC is independent of the

keyboard layout

• Zero-Power operation,

transparent to the Host

• Average current consumption of

less than 1µA at room

temperature; 10µA at 85°C

• Customized versions available

• TTL/CMOS Output-only

Asynchronous Serial Interface

to the Host (direct connection to

the UART)

• Very simple serial protocol —

Two-Byte Identification String on

power-up; single-Byte Matrix-

position for each key-press or

key-release

UR5HC703 is an extremely

low-power, “off-the-shelf” serial

keyboard encoder. Robust, tiny

and flexible, the IC is a good

match for any application where

the use of complicated keyboard

protocols are not required and

where asynchronous serial

interface hardware is available.

• Robust algorithm for Ghost-key

elimination

The USAR SerialCoder provides

Applications

unprecedented power

consumption minimization, making

it ideal for use in add-on keyboards

for handheld and cellular / web

phones and single-board systems

designed for portable applications.

• Portable Personal Computers

• Instrumentation

• Remote Control

• Built-in keyboards for HH

PDAs/Organizers

• Add-on accessory keyboards for

Palm and H/PC Devices

• Cellular Phones

Pin Assignments

The IC provides Zero-Power

operation, transparent to the host.

Power consumption is reduced to

just the circuit’s leakage when all

keys are released. The average

current consumption is less than

1µA at room temperature and 10µA

at 85°C. If a single key or groups

of keys are stuck in the depressed

position, the IC will enter a total

shutdown after a 10-minute wait —

to protect against unintended and

unnecessary discharge of the

batteries in the Host.

Custom versions of the USAR

SerialCoder are available with

Hardware Handshaking for the

Communication channel, support

for extra-low-power operations of

the Host, various baud rates and

Full-Duplex I/O, etc. The USAR

SerialCoder is simple to

implement. It requires few external

components and utilizes a tiny, low-

profile 32-pin LQFP package that

measures 7mm x 7mm.
