8 x 16 matrix encoding
9600 Baud 8N1 serial data format
Custom matrix in a simple driver
Extremely low power consumption,
average less than 1 A
LQFP or MLPQ package
Robust algorithm for ghost-key
elimination
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
The SH703600 SerialCoder is an
extremely low-power, “off-the-shelf”
serial keyboard encoder. Robust,
tiny and flexible, the SH703600 is a
good match for any application
where complicated keyboard
protocols are not required and
asynchronous serial interface
hardware is available.
The SH703600 provides
unprecedented power consumption
minimization, making it ideal for
use in embedded or add-on
keyboards for handheld and
cellular / web phones and single-
board systems designed for
portable applications. The
SH703600 provides extremely low-
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 1 A.
If a single key or groups of keys
are stuck in the depressed position,
the SH703600 enters a total
shutdown after a 10-minute wait —
to protect against unintended and
unnecessary discharge of the
batteries in the host.
The SH703600 is simple to
implement and requires few
external components. It is
available in a 7 mm x 7 mm 32-pin
LQFP package or a 6 mm x 6 mm
36-pin MLPQ package.
APPLICATIONS
Accessory keyboards for personal
digital assistants (PDAs) and hand-
held PCs (H/PCs)
Built-in keyboards for PDAs and
H/PCs
Portable personal computers
Instrumentation
Remote control
Smart phones
Web phones
