Semtech offers 8- to 22-bit microcontrollers that interface sensors and radio transceivers and target autonomous, battery-operated, wireless devices. These devices operate at a constant one instruction per clock that is independent of the type of operation and addressing mode. The Radio Machine device for ISM (industrial/scientific/medical)-band-transceiver interfacing includes a low-power RISC core with the BitJockey, a serial interface for radio protocols, and a UART. Semtech offers tools and application notes for radio development. The Sensing Machine device for sensor interfacing includes a low-power RISC core with the high-resolution ZoomingADC sigma-delta ADC and a programmable preamplifier.
