Analog Devices / Maxim Integrated MAX7037 Sub-1GHz Ultralow-Power RF ISM Transceiver

Analog Devices MAX7037 Sub-1GHz Ultralow-Power RF ISM Transceiver is a high-performance quad-band multichannel transceiver with an integrated 8051 microcontroller, flash memory, and sensor interface. The MAX7037 has a 2.1V minimum supply voltage to extend battery life and allow different energy sources to be used as solar cells, electromechanical, or thermoelectrical energy. The transceiver features hardware-implemented transmit-and-receive routines in combination with a microcontroller. This enables a high-efficiency transceiver system for wireless fail-safe multiband/multichannel communication with advanced FSK and ASK protocol features. Sleep modes allow easy implementation of low-power applications with fast reaction times.
