Analog Devices’ Analog Microcontroller with ARM Cortex M3 and Dual
24-Bit Sigma-Delta A/D Converters Offers
Highest Accuracy, Lowest Power
June 4, 2012 Press Release
-- ADuCM360 draws 1-mA operating current for full operation of processor and analog front-end to enable 4-
to 20-mA loop-powered smart sensor applications.
WIRE)-- 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.
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
ADuCM360 Analog Microcontroller Key Features and Benefits
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.
- 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.
This new data acquisition system is available in a 48-lead, 7mm x 7mm LFCSP package and operates from a 1.8-V to
