Micrel, represented by Soanar in Australia and New Zealand, have introduced a parallel encoder MICRF302. It works with QwikRadio family radios to significantly shorten design time for RF products. The part is easy to use, ensures data integrity 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. The MICRF302 outputs encoded data serially, and can be connected directly to any QwikRadio transmitter without additional components. The MICRF302 gives communication reliability through built-in CRC (cyclic redundancy check). Unlike other encoders on the market, there is no shift in performance with associated changes in operating temperature or operating voltage. The internal clock needs no external components and provides stable data operations over a wide temperature range from –40°C to +85°C. MICRF302 can operate from 1.8V to 3.6V. The MICRF302 is battery friendly and will work with alkaline, NiCd, NiMh, lithium ion or lithium batteries.
Features of the MICRF302 parallel encoder include:
- Low current consumption: 130µA operating, 0.1µA standby
- Unique 20-bit internal address allows up to 1 million combinations to differentiate from adjacent encoders.
- Selectable data rates: 0.6, 1, 3, 4.8kbps
- Available in a 10-pin MLF package
