Description
Features
The USAR SerialCoderTM
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.
The USAR SerialCoderTM provides
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.
The IC provides Zero-PowerTM
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
SerialCoderTM 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
SerialCoderTM is simple to
implement. It requires few external
components and utilizes a tiny, low-
profile 32-pin LQFP package that
measures 7mm x 7mm.
• 8 x 16 Matrix Encoding
• 9600 Baud 8N1Serial Data Format
• IC is independent of the
keyboard layout
• Zero-PowerTM operation,
transparent to the Host
• Average current consumption of
less than 1µA at room
temperature; 10µA at 85°C
• Customized versions available
Applications
• 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
• Robust algorithm for Ghost-key
elimination
• Built-in keyboards for HH
PDAs/Organizers
• Add-on accessory keyboards for
Palm and H/PC Devices
• Portable Personal Computers
• Instrumentation
• Remote Control
• Cellular Phones
