RFM12B
(the purpose of this spec covers mainly for the
RFM12B
physical characteristic of the module, for register
configure and its related command info please refer
to
RF12B data
sheets)
General Introduction
RFM12B is a low costing ISM band transceiver
module implemented with unique PLL. It works
signal ranges from 433/868/915MHZ bands, comply
with FCC, ETSI regulation. The SPI interface is
used to communicate with microcontroller for
parameter setting.
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 2.5 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/output
• Automatic antenna tuning
• Programmable TX frequency deviation (from 15 to 240 KHz)
• Programmable receiver bandwidth (from 67 to 400 kHz)
• Analog and digital signal strength indicator (ARSSI/DRSSI)
• Automatic frequency control (AFC)
• Data quality detection (DQD)
• Internal data filtering and clock recovery
• RX synchron pattern recognition
• SPI compatible serial control interface
• Clock and reset signal output for external MCU use
• 16 bit RX Data FIFO
• Two 8 bit TX data registers
• Standard 10 MHz crystal reference
• Wakeup timer
• 2.2V – 3.8V power supply
• Low power consumption
• Standby current less than 0.3uA
• Supports very short packets (down to 3 bytes)
