The DWM-HC210C is a low-cost sub-1 GHz transmitter designed for very low-power wireless applications. The circuit is mainly intended for the ISM (Industrial, Scientific and Medical) and SRD(Short Range Device) frequency bands at 315, 433, 868, and 915 MHz, but can easily be programmed for operation at other frequencies in the 300-348 MHz, 387-464 MHz and 779-928MHz bands.
Suited for systems targeting compliance with EN 300 220 (Europe) and FCC CFR Part 15 (US)．
Suited for systems targeting compliance with the Wireless MBUS standard EN 13757-4:2005
Support for asynchronous and synchronous serial receive/transmit mode for backwards compatibility with existing radio communication protocols.
