- RFM12 is a low costing ISM band transceiver module implemented with unique PLL. It works signal ranges from 433, 868, 915MHz bands, and complies with FCC and ETSI regulations. The SPI interface is used to communicate with micro-controller for parameter setting
- RFM12 has three packages: DIP, SMD1 and SMD2 (SMD2 is thinner and smaller than SMD1 due to the crystal size)
- Features:
- Low costing, high performance and price ratio
- Tuning free during production
- PLL and zero IF technology
- Fast PLL lock time
- High resolution PLL with 2.5kHz step
- High data rate (up to 115.2kbps with internal demodulator)
- Differential antenna input
- Automatic antenna tuning
- Programmable TX frequency deviation (15 to 240kHz)
- programmable receiver bandwidth (67 to 400kHz)
- Analog and digital signal strength indicator (ARSSI/DRSSI)
- AFC
- DQD
- Internal data filtering and clock recovery
- RX synchronous pattern recognition
- SPI interface
- Clock and reset signal output for external MCU use
- 16-bit RX data FIFO
- Two 8-bit TX data registers
- 10MHz crystal for PLL timing
- Wake-up timer
- 2.2 to 5.4V power supply
- Low power consumption
- Stand by current less than 0.3 μA
