Norwood, MA (06/04/2012) - Analog Devices, Inc. (NASDAQ: ADI), the data converter market share leader*, today introduced the ADuCM360, a fully integrated, 4-kSPS, 24-bit data acquisition system-on-a-chip incorporating dual, high-performance, multi-channel sigma-delta A/D converters, a 32-bit ARM CortexTM M3 MCU, and flash/EE memory. This device draws 1-mA of operating current and is designed for direct interfacing to external 4- to 20-mA loop-powered precision sensors in industrial process control. Low sleep current further enhances ADuCM360 use in battery powered applications.
The ADuCM360 microcontroller core is a low power 32-bit ARM RISC machine and incorporates a flexible 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.
The ADuCM360 analog sub-system consists of two A/D converters connected to a flexible input multiplexer (with up to 11 input channels) and each with its own programmable gain amplifier. Both converters can operate in fully differential or single-ended modes. The ADuCM360 is ideal for applications where the second A/D converter is needed for temperature compensation on the sensor or for dual-sensor applications. Available in August will be the ADuCM361, which contains all the features of the ADuCM360 but includes only one A/D converter.
“The ADuCM360 consumes just 1 mA in full operation, with both A/D converters and programmable gain amps active, making them ideal for use in 4- to 20-mA loop-powered systems,” said Leo McHugh, director Precision A/D Converters, Analog Devices. “The ADuCM360/361 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.”
On-chip factory firmware supports in-circuit serial download via a serial wire interface (2-pin JTAG system) and UART while non-intrusive emulation is also supported via the serial wire interface. These features are incorporated into a low-cost QuickStart™ Development Kit supporting this precision analog microcontroller family.
This new data acquisition system is available in a 48-lead, 7mm x 7mm LFCSP package and operates from a 1.8-V to 3.3-V supply.
Samples and the QuickStartTM Development Kits are currently available.
