USAR SerialCoderTM UR5HC703-600-FG
USAR SerialCoderTM Low-Power Keyboard Encoder interfaces RS-232
Description 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.
