ZL70251
Ultra-Low-Power Sub-GHz RF Transceiver (779 MHz to 965 MHz)
Overview
Microsemi’s ZL70251 RF transceiver is the lowest-power sub-GHz ISM-band radio for continuous-monitoring, wireless-sensor applications. Because both continuous and peak power supply requirements are ultralow, the ZL70251 is the industry’s leading choice for sensor networks that are powered by a coin-cell battery or an energy-harvesting power source.The ZL70251 is also highly integrated. Besides the antenna and in some cases its matching network, only a crystal, resistor, and two decoupling capacitors are required. Available as a 2-mm-by-3-mm CSP, the device enables applications with a very small footprint.
The ZL70251 device operates in unlicensed frequency bands between 779 MHz and 965 MHz and offers a maximum data rate of 186 kbit/s to support voice communication. For data communication, the ZL70251 supports extremely low power consumption in packet-based networks.
The device includes the RF transceiver as well as a Media Access Controller (MAC) that performs most link support functions including Received Signal Strength Indication (RSSI), Clear Channel Assessment (CCA), sniff, preamble and sync, packetization, and whitening. The device uses standard interfaces, enabling easy integration with a standard microcontroller or Digital Signal Processor (DSP).
