The MC13191 is a short range, low power, 2.4 GHz band transceiver designed for low-cost, simple point-to-point and star network applications. The MC13191 includes a complete packet modem capable of formatting data into packets with 125 byte payload. It has an over the air data rate of 250 kbps using O-QPSK modulation and Direct Sequence Spread Spectrum (DSSS) coding.
When combined with an appropriate microcontroller unit (MCU) as a baseband processor, the MC13191 provides a complete and cost effective wireless node for point to point and simple star network applications. Interface with the MCU is accomplished via a four wire serial peripheral interface (SPI) which allows interface to a variety of processors.
