Introduction

Thank you for choosing Radicom RB9500Module. We are committed to providing you
quality service and technical support. The RB9500modules are designed to meet OEM’ s
needs of embedding short-ra n ge, low power, wi reless data connectivity to their prod ucts. The
RB9500offers a quick and simple solution for wireless 2.4GHz FSK/GFSK Transceiver.

The RB9500 module 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, RB9500has special strength for long
LOS (line-of-sight) distance because of its ultra high sensitivity (-107 dBm @ 2Kbps, - 104
dBm @ 25Kbps) with no requirem ent of external LNA or PA. Based on Data Rate Register
(0x0E), user can configure on-air data rates from 2Kbps to 500Kbps.

The RB9500module 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 cod e w ord, RSSI for clear channel assessment, data
whitening for data encryption / decryption.

For power saving, RB9500supports sleep mode, idle mode, standby mode. For easy-to-use,
RB9500has 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,
RB9500supports two general purpose I/O pins, GIO1 and GIO2, to inform MCU its status so
that MCU could use either polling or interr upt scheme to do radio control. Hence, it is very
easy to monitor radio transmission between MCU and RB9500via digital interface.

Important Information about FCC, IC, CE Certification

RB9500 series is using 2.4GHz ISM band with non-standard protocol for transmitting power,

timing, cadence and modulation. Therefore, any firmware involved to change thos e

parameters will affect to FCC/IC/CE Certification.
