描述 Description

Ultra-Low-Power Sub-GHz RF Transceiver (779 MHz to 965 MHz)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).FeaturesUltralow transmit and receive current of less than 2.4 mALow supply voltage of 1.2 V to 1.9 VOperates between 779 MHz and 965 MHz (915-MHz ISM band in North America; 868-MHz SRD band in Europe; 779-MHz to 787-MHz band in China)High data rate (186 kbit/s raw)Very small footprintFew external components (crystal, resistor, and two decoupling capacitors)CSP package: 2 mm by 3 mmStandard interfacesSPI bus master for packet dataTwo-wire for status and controlIntegrated MAC performing all link layer basic functionsFull functionality over industrial temperature range (−40°C to +85°C)Third-Party ApplicationsVirtual Extension's VEmesh Wireless Mesh NetworkDesign ResourcesThe following kits are available to assist developers with evaluating the ZL70251 for use in a wireless sensor network or with designing RF communications systems using the ZL70251.ZL70251 WSN Evaluation Kit with Z-Star ProtocolZL70251 Application Development Kit (ADK) ZL70251 WSN Evaluation Kit with Z-Star Protocol ZL70251 Application Development Kit (ADK)
