RFM69HCWRFM69HCW ISM TRANSCEIVER MODULE v 1 . 1GENERAL DESCRIPTIONTALNDThe RFM69HCW is a transceiver module capable ofoperation over a wide frequency range, including the315,433,868 and 915MHz license-free ISM (IndustryScientific and Medical) frequency bands. All major RFcommunication parameters are programmable and most ofthem can be dynamically set. The RFM69HCW offersthe unique advantage of programmable narrow-band andwide- band communication modes. The RFM69HCW isoptimized for low power consumption while offering high RFoutput power and channelized operation. Compliance ETSIand FCC regulations.In order to better use RFM69HCW modules, thisspecification also involves a large number of theparameters and functions of its core chip RF69H's,includingthose IC pins which are not leaded out. All of these can helpcustomers gain a better understanding of the performanceof RFM69HCW modules, and enhance the application skills.KEY PRODUCT FEATURESRFM69HCWAPPLICATIONS Automated Meter Reading Wireless Sensor Networks Home and Building Automation 20 dBm - 100 mW Power Output Capability Wireless Alarm and Security Systems High Sensitivity: down to -120 dBm at 1.2 kbps Industrial Monitoring and Control High Selectivity: 16-tap FIR Channel FilterBullet-proof front end: IIP3 -18 dBm, IIP2 35 dBm,80dB Blocking Immunity, no Image Frequency response Wireless M-BUS Low current: Rx 16 mA, 100nA register retention Programmable Pout: -18 to 20 dBm in 1dB steps Constant RF performance over voltage range of module FSK Bit rates up to 300 kb/s Fully integrated synthesizer with a resolution of 61 Hz FSK, GFSK, MSK, GMSK and OOK modulations Built-in Bit Synchronizer performing Clock Recovery Incoming Sync Word Recognition 115 dB Dynamic Range RSSI Automatic RF Sense with ultra-fast AFC Packet engine with CRC-16, AES-128, 66-byte FIFOBuilt-in temperature sensor Module Size:16X16mmPage 1Tel: 86-755-82973805 Fax: 86-755-82973550 E-mail: sales@hoperf.com http:/ / www.hoperf.com
