General Description
The MICRF302 is a parallel encoder which works with
QwikRadio
family radios to significantly shorten design
time for RF products. The part is easy to use, provides
more communication distance, and it is extremely stable
over operating temperature and operating voltage range.
The MICRF302 Parallel Encoder makes the transmission
of encoding data simple. This device encodes data from
four input pins, which have internal pull-up resistors and
deglitching circuitry. These inputs can be connected to
switches or external circuitry.
The MICRF302 outputs
encoded data serially, and can be connected directly to
any QwikRadio
transmitter without any additional
components.
The MICRF302 gives communication reliability through
built-in CRC (cyclic redundancy check). The MICRF302
needs no external components for clock generation.
Unlike other encoders on the market, there is no shift in
performance with associated changes in operating
temperature nor operating voltage. The internal clock
provides stable data operations over a wide temperature
range of -40°C to +85°C.
MICRF302 can operate from
1.8 V to 3.6 V. The MICRF302 is battery friendly, and will
work with alkaline, NiCd, NiMh, lithium ion, or lithium
batteries.
