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.?
