Product Information

w i r e l e s s IA4430/31/32 DESCRIPTION EZRadioPRO™ PRODUCT FEATURES • • • • • • • • • • • • Frequency Range = 240-960MHz Sensitivity =-117dBm Data Rate = 1-128kbps +13dBm Max Output Power Version (Configurable –8 to +13dBm) +20dBm Max Output Power Version (Configurable +11 to +20dBm) Power Supply = 1.8-3.6V Ultra Low Power Sleep Mode Digital RSSI 20-Pin QFN Package On-chip Crystal Tuning Green Lead Free package Wake-On-Radio • • • • • • • • • • Auto-Frequency Calibration (AFC) Configurable Packet Structure Preamble Quality Detector TX & RX 64 byte FIFOs Low Battery Detector Low Power Consumption – 17mA Receive – 21mA Transmit @+13dBm (IA4431) – 60mA Transmit @+20dBm (IA4432) Low BOM -40°C - +85°C Temperature Range Integrated Voltage Regulators Antenna Diversity & TR Switch Control Universal ISM Band Transceiver 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 incorporates 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 a 30MHz crystal and www.DataSheet4U.com supply bypass capacitors are necessary as external components, making the devices ideal for high volume production in applications where size and cost are important.
