Radicom RB9500 modules are designed to meet OEM’s needs of embedding short-range, low power, wireless data connectivity to their products. It offers a quick and simple solution for wireless 2.4GHz FSK/GFSK Transceiver. It is designed for 2.4GHz ISM band wireless applications. The module integrates both high sensitivity receiver (- 95dBm @ 500Kbps) and high efficiency power amplifier (up to 1dBm). In low data rate application, RB9500 has special strength for long LOS (line-of-sight) distance because of its ultra high sensitivity (-107 dBm @ 2Kbps, - 104 dBm @ 25Kbps) with no requirement of external LNA or PA. Based on Data Rate Register (0x0E), user can configure on-air data rates from 2Kbps to 500Kbps.
The RB9500 module supports fast settling time (130 us) for frequency hopping system. For packet handling, the RB9500 has built-in separated 64-bytes TX/RX FIFO (could be extended to 256 bytes) for data buffering and burst transmission, CRC for error detection, FEC for 1-bit data correction per code word, RSSI for clear channel assessment, data whitening for data encryption / decryption.
For power saving, RB9500 supports sleep mode, idle mode, standby mode. For easy-to-use, RB9500 has an unique SPI command set to control internal state machine. Based on the command set via SPI bus, MCU can control everything from power saving, TX delivery, RX receiving, channel monitoring, frequency hopping to auto calibrations. In addition, RB9500 supports two general purpose I/O pins, GIO1 and GIO2, to inform MCU its status so that MCU could use either polling or interrupt scheme to do radio control. Hence, it is very easy to monitor radio transmission between MCU and RB9500 via digital interface. Features:
