IA4430/31/32 EZRadioPRO
Universal ISM Band Transceiver
DESCRIPTION
Integration’s IA443x series of transceivers are members of the new EZRadioPROTM product family. While
retaining all the attractive features of the earlier products such as high integration, low cost, flexibility, low
BOM, and easy design-in, these parts are targeted to more sophisticated applications and offer several
enhanced parameters and features, including continuous frequency coverage from 240-960MHz, and
output power up to +20dBm. Also included are built-in features like wake-up timer, low battery detector,
transmit and receive data FIFOs, power-on reset circuit, and general purpose digital I/Os. The chip incor-
porates a high performance ADC and digital modem which perform demodulation, filtering, and packet
handling in the digital domain, making it ideal for configuration to mutiple applications. These features
simplify the task of the system designer and allow the use of lower-end microcontrollers. The 4432 has
configurable output power from +11 to +20dBm and is ideal for Frequency Hopping Systems where
maximum range is desired. The 4430/31 have configurable output power from -8 to +13dBm. Both the
4431 and 4432 comply with FCC and ETSI requirements when used in any of the standard ISM Bands. Only
