The MAX7037 is an ultra-low-power high-performance quad band multichannel transceiver with integrated 8051 microcontroller, flash memory, and sensor interface. The MAX7037 runs from a minimum supply voltage of only 2.1V, extending battery life and also enabling it to cope with different sources of energy like solar cells, electromechanical, or thermo electrical energy. Hardware-implemented transmit-and-receive routines in combination with a microcontroller enable 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.
