| RFM02 Datasheet REV1.2 ISM BAND FSK TRANSMITTER MODULE RFM02 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 RF02 data sheets RFM02 General Introduction RFM02 is a low costing ISM band transmitter module implemented with unique PLL approach. It works with FSK modulated signal ranges from 433/868/915MHZ bands, comply with FCC, ETSI regulation. The SPI interface is used to communicate with microcontroller for parameter setting. RFM02 works with RFM01 receiver 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 transmission * PLL employed * Fast PLL lock time * High resolution PLL with 2.5 KHz step * Programmable frequency deviation (from 30 kHz to 210 kHz, step 30 kHz) * Programmable output power * High data rate (up to 115.2 kbps with FSK modulation) * Differential antenna output * Automatic antenna tuning * SPI interface * Clock and reset signal output for external MCU use * 10MHz crystal for PLL reference * Programmable crystal load capacitor bank * Wakeup timer * low battery detection * 2.2V - 5.4V power supply * Low power consumption * stand by current less than 0.3A Tel: +86-755-82973805 Fax: +86-755-82973550 E-mail: sales@hoperf.com http://www.hoperf.com RFM02 Datasheet REV1.2 Typical Application * Remote control * Remote sensor * Wireless data collection * Home security system * Toys * Tire pressure monitoring system Pin Definition SMD DIP Definition FSK CLK VDD nIRQ SDI SCK VSS nSEL TYPE DI DO S DO DI DI S DI function FSK data input clock out for MCU (1 MHz-10 MHz) Positive power supply Interrupts request outputactive low SPI data input SPI clock input negative power supply, GND Chip select (active low) Tel: +86-755-82973805 Fax: +86-755-82973550 E-mail: sales@hoperf.com http://www.hoperf.com RFM02 Datasheet REV1.2 Electrical Specification Maximumnot at working mode symbol Vdd Vin Iin ESD Tst Tld parameter Positive power supply All pin input level Input current except power Human body model Storage temperature Soldering temperature(10s) -55 min -0.5 -0.5 -25 max 6.0 Vdd+0.5 25 1000 125 260 unit V V mA V Recommended working range symbol Vdd Top parameter Positive power supply operation temperature min 2.2 -40 max 5.4 85 unit V DC Characteristics symbol Idd_TX_0 parameter current consumption 433 MHz band 868 MHz band 915 MHz band current Idd_TX_PMAX Ipd Iwt Ilb Ix Vlba Vlb Vil Vih Iil Iih consumption 433 MHz band 868 MHz band 915 MHz band sleep mode current waek-up timer current consumption low battery detector current consumption idle mode current low battery detection accuracy low battery detection range Low level input High level input Leakage current Leakage current Vil = 0 V Vih = Vdd, Vdd = 5.4V Vol Voh Low level output High level output Iol = 2 mA Ioh = -2 mA Vdd-0.4 0.4 V V 0.7*Vdd -1 -1 1 1 0.1V step 2.2 only crystal work 1.5 75 5.3 0.3*Vdd mA mV V V V A A all blocks off max power output conditions/note 0 dBm power output min typ 12 14 15 23 25 26 0.3 1.5 0.5 A A A mA mA max unit Tel: +86-755-82973805 Fax: +86-755-82973550 E-mail: sales@hoperf.com http://www.hoperf.com RFM02 Datasheet REV1.2 DC Characteristics symbol fref fo parameter PLL reference frequency Output frequency fref=10MHZ fo conditions/notes Parallel fundamental 433MHz band,2.5kHz step 868MHz band,5.0kHz step 915MHz band,7.5kHz step 433MHz band,2.5kHz step Output frequencyfref=9MHZ 868MHz band,5.0kHz step 915MHz band,7.5kHz step 433MHz band,2.5kHz step fo tlock tsp Pmax Co Qo BRFSK dffsk Cxl tPBt twake-up tPOR tsx Output frequency fref=11MHZ 868MHz band,5.0kHz step 915MHz band,7.5kHz step PLL lock time PLL start time Max available ouput power After 10MHz step hopping, frequency error <10 kHz After crystal stabilized 433MHz band 868MHz band 915MHz band output capacitance(set by antenna tuning circuit) Q factor of output capacitance FSK data rate FSK deviation crystal load capacitance period of wake-up timer clock wake-up time(programable) internal POR time Crystal start time after power reached 90% VDD ESR < 100 ohms 5 ms 30KHz step 0.5pF +/-10% calibrated evry 30 seconds 0.95 1 1.05 2*10E9 100 ms ms ms step,tolerance 30KHz 8.5 low bands high bands 5 2 2 1.5 1.6 16 7 4 4 2.3 2.2 18 3.1 2.8 22 115.2 210 16 kbps kHz pF pF dBm 250 s min 9 430.24 860.48 900.72 387.22 774.43 810.65 473.26 946.53 990.79 20 typ 10 max 11 439.75 879.51 929.27 395.76 791.56 836.34 483.73 967.46 1022.2 s MHz MHz MHz unit MHz Field testing range operation band 433MHz band condition Bandwidth=134KHz, data rate=1.2kbps Frequency deviation=60KHZmatches with RFM01 in free open area 868MHz band Bandwidth=134KHz, data rate=1.2kbps Frequency deviation=60KHZmatches with RFM01 in free open area 915MHz band Bandwidth=134KHz, data rate=1.2kbps Frequency deviation=60KHZmatches with RFM01 in free open area Tel: +86-755-82973805 Fax: +86-755-82973550 E-mail: sales@hoperf.com http://www.hoperf.com >200m >200m >200m range RFM02 Datasheet REV1.2 SGS Reports Tel: +86-755-82973805 Fax: +86-755-82973550 E-mail: sales@hoperf.com http://www.hoperf.com RFM02 Datasheet REV1.2 Tel: +86-755-82973805 Fax: +86-755-82973550 E-mail: sales@hoperf.com http://www.hoperf.com RFM02 Datasheet REV1.2 Mechanical Dimension: all dimensions in mm SMD PACKAGES1 SMD PACKAGES2 DIP PACKAGED Tel: +86-755-82973805 Fax: +86-755-82973550 E-mail: sales@hoperf.com http://www.hoperf.com RFM02 Datasheet REV1.2 Module Definition model=module-operation_band-package_type RFM02B-433-D module type operation band Package eg1RFM02 module at 433MHz band, DIP : RFM02-433-D 2RFM02 module at 868MHz band, SMD, thickness at 4.2mm : RFM02-868-S1 This document may contain preliminary information and is subject to change by Hope Microelectronics without notice.
