1 RF Transceiver Mdule Applicatins Ultra lw pwer wireless Transceiver 433/868/915 and 2400 Mhz ISM/SRD band systems Cnsumer Electrnics Wireless audi Alarm and security systems Hme and building autmatin Wireless sensr netwrks Industrial mnitring and cntrl Lw pwer Telemetry Prduct Descriptin The BITxxRT is a very lw cst transceiver mdule designed fr very lw pwer wireless applicatins. This mdule is intended fr ISM (Industrial, Scientific and Medical) and SRD (Shrt Range Device) frequency band at 433, 868/915 and 2400 Mhz., but can easily be prgrammed fr peratin at ther frequencies: BIT04RT Mhz BIT08RT Mhz BIT24RT Mhz BITxxRT prvides extensive hardware supprt fr packet handling, data buffering, burst transmissins, clear channel assessment, link quality indicatin and wake-n-radi. The main perating parameters and the 64-byte transmit/receive FIFOs f BITxxRT can be cntrlled via an SPI interface. In a typical system, the BITxxRT will be used tgether with a micrcntrller. The Transceiver mdule supprts varius mdulatin frmats and has a cnfigurable data rate up t 500 kbps. The cmmunicatin range can be increased by enabling a Frward Errr Crrectin ptin, which is integrated in the mdule. BITxxRT has a very small package nly 20 x 20 mm ready fr bth PTH and SMT assembly. BITxxRT is based n the well-prven CC1101 (BIT04RT and BIT08RT), CC2500 (BIT24RT) Chipcn Prducts frm Texas Instruments. Key Features Small size (20 x 20 mm package, 12 pins). Frequency bands: 1. BIT04RT MHz 2. BIT08RT MHz 3. BIT24RT Mhz. Bit is Italian Technlgy S.r.l. BITxxRT Preliminary Datasheet (Rev ) Pagina 1 di 8
