RFM01 Datasheet REV1.2 ISM BAND FSK RECEIVER MODULE RFM01 （the purpose of this spec covers mainly for the physical characteristic of the module, for register configure and its related command info please refer to RF01 data sheets） RFM01 General Introduction RFM01 is a low costing ISM band receiver module implemented with unique PLL and zero IF design approach. It works with FSK modulated signal ranges from 315/433/868/915MHZ bands, comply with FCC, ETSI regulation. The SPI interface is used to communicate with microcontroller for parameter setting. RFM01 works with RFM02 transmitter module. At 433MHZ band, the pair of module can work up to 300m in the free open air. Features: • Low costing, high performance and price ratio • Tuning free during production • FSK reception • PLL and zero IF technology • Fast PLL lock time • High resolution PLL with 2.5 KHz step • High data rate (up to 115.2 kbps with internal demodulator，with external RC filter highest data rate is 256 kbps) • Differential antenna input • Automatic antenna tuning • Programmable receiver bandwidth (from 67 to 400 kHz) • Analog and digital signal strength indicator (ARSSI/DRSSI) • AFC • DQD • Internal demodulator • SPI interface • Clock and reset signal output for external MCU use • 16 bits FIFO • Low power mode (<0.5mA averaged current consumption) • 10MHz crystal for PLL timing • Wakeup timer • Low battery detection • Programmable capacitor bank • 2.2V - 5.4V power supply • Low power consumption • Stand by current less than 0.3uA Tel: +86-755-82973805 Fax: +86-755-82973550 E-mail: [email protected] http://www.hoperf.com RFM01 Datasheet REV1.2 Typical Application： • Remote
