Based on an open-source ARM Cortex-M3 processor, recently Analog Device Inc (ADI) introduced a newradio SoC, ADuCRF101, which is designed for a range of remote, battery-powered wireless sensor network (WSN) applications by combining a 12-bit ADC (analog-to-digital converter), low-power 32-bit processing, large on-chip memory and high-performance RF communications in a single 9-mm × 9-mm package. Thus, it simplifies design and reduces development time in designing wireless data-acquisition products.
Indeed, this new Radio SoC device also offers a single-chip communications solution for the challenging requirements of battery powered gas, water and heat meters at low power consumption and good penetration.
ADI ADuCRF101 radio SoC is available in two option Flash/SRAM memory density: 64/8Kb($4.05/each for 1000 pieces) and 128/16Kb ($4.50/each for 1000 pieces). [Dandy Gadget Source]
