Analog Devices, which according to industry analyst firm Databeans is the data converter market share leader (2011) with a 48.5 percent share, has announced the ADuCM360, a 4-kSPS, 24-bit data acquisition system-on-a-chip (SoC) said to delivers the industry’s highest accuracy analog conversion and more processing-per-mW of power than any other analog microcontroller solution for industrial smart sensor applications.
incorporating dual, high-performance, multi-channel sigma-delta A/D converters, a 32-bit ARM CortexTM M3 MCU, and flash/EE memory the device draws 1-mA of operating current and is designed for direct interfacing to external 4- to 20-mA loop-powered sensors in industrial process control. Low sleep current further enhances ADuCM360 use in battery powered applications.
The ADuCM360 microcontroller core is a 32-bit ARM RISC machine and incorporates an 11-channel DMA (direct memory access) controller supporting wired (SPI, UART, I²C) communication peripherals. In addition there are 128k bytes of non-volatile flash/EE and 8k bytes of SRAM, all integrated on-chip.
