ZL70250
Description
The ZL70250 ultra-low-power RF transceiver provides a wireless link in applications where power consumption is of primary importance. The transceiver’s ultralow power requirements allow the use of a coin-cell battery or energy-harvesting methods, enabling devices with extremely small form factors.
