BC3601 QFN24

The BC3601 is a high performance and low cost CMOS RF FSK/GFSK transceiver for wireless applications in the 315MHz, 433MHz, 470MHz, 868MHz and 915MHz ISM (Industrial, Scientific and Medical) frequency bands. It incorporates a baseband modem with a programmable data rate from 2Kbps to 250Kbps. Data handling features include 64-byte TX/RX FIFO, packet handling, CRC generation, Forward Error Correction and data whitening, Manshester encoding.
