Datasheet, Revision 4 ZL70250 Ultra-Low-Power Sub-GHz RF Transceiver Features Applications Ultralow Power Body-Area Network Typical TX Current (at 50- match): Energy Harvesting < 2 mA at 13 dBm < 5 mA at 2 dBm Wireless Sensor Network Typical RX Current: < 1.9 mA Remote Control Sleep Current: < 500 nA Voice/Compressed Audio Communication Supply: 1.2 V to 1.8 V RF Switch Radio Operating Frequency Range: 795 to 965 MHz Active RFID North American ISM Band: 902 to 928 MHz Inventory Management European SRD Bands: 863 to 870 MHz Radio Performance Description Raw Data Rate: 186 kbit/s TX Power: up to 0 dBm The ZL70250 ultra-low-power RF transceiver provides a wireless RX Sensitivity: 90 dBm Typical at 186 kbit/s link in applications where power consumption is of primary Very Few External Components importance. The transceivers ultralow power requirements allow Only Crystal and Bias Resistor the use of a coin-cell battery or energy-harvesting methods, Standard Interfaces enabling devices with extremely small form factors. SPIbus Master for Packet Data The ultra-low-power device operates in unlicensed frequency Two-Wire for Status and Control bands between 795 and 965 MHz with a data rate of 186 kbit/s to MAC support voice/compressed audio communication. Duty cycling can Clear Channel Assessment be employed for applications that require lower average payload to Sniff with Automatic Receive or Sleep further reduce power consumption.
