ISM BAND FSK RECEIVER MODULE
RFM01
Datasheet REV1.2
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
General Introduction
RFM01
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 demodulatorwith 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
