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.”
ADuCM360 Analog Microcontroller Key Features and
Benefits
- A complete, single-chip analog
front-end including input signal conditioning, dual PGAs, voltage
reference, dual 24-bit sigma-delta A/D converters and a buffered
voltage-output D/A converter resulting in higher accuracy, reduced
board space and lower power consumption.
- An integrated, low power, 32-bit,
20-MIPs ARM Cortex M3 core enables advanced diagnostics at a sensor
node – wired or wireless – for higher accuracy measurements.
- Up to 12 programmable sensor excitation
current sources from 10µA to 1mA can be used with bridge sensors
and resistive temperature sensors.
- The on-chip D/A converter that can be
used for 4- to 20-mA loop control.
- Supported with the low-cost
QuickStartTM Development Kit, which includes sample code, function
libraries, compilers and emulators for faster and less expensive
software development.
- Specified for a wide industrial
temperature range of –40°C to +125°C.
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.
