Analog Devices’ Radio System-on-Chip Combines Data Conversion,
- New SoC device simplifies embedding RF in wireless sensor networks.
RF and 32-Bit Processing to Enable
Power-Efficient Wireless Connectivity
NORWOOD, Mass.--(BUSINESS WIRE)-- Analog Devices, Inc. (NYSE: ADI), the leading supplier of data converters
and a global leader in high-performance semiconductors for signal-processing applications, today introduced a SoC
(system-on-chip) device that integrates all of the RF (radio frequency) transmit and receive functions, data
conversion, and processing elements required to enable a fully programmable radio. Designed for a range of remote,
battery-powered wireless sensor network (WSN) applications, including utility meters, medical telemetry systems,
building automation, asset tracking and security systems, the ultra-low-power ADuCRF101 radio SoC features a
12-bit ADC (analog-to-digital converter), a 32-bit microprocessor core, on-chip SRAM and FLASH memory and an
ISM-band radio transceiver. Download the

combining converter technology, low-power 32-bit processing, large on-chip memory and high-performance RF
communications in a single 9-mm × 9-mm package, the ADuCRF101 provides a radio SoC at a performance level not
previously available to battery-powered WSN applications,” said James Caffrey, Converter Group marketing and
applications director, Analog Devices. “By delivering a solution based on an open-source ARM® Cortex™-M3
processor, combined with evaluation hardware and software tools, the Analog Devices platform simplifies design and
reduces development time for our customers who are designing wireless data-acquisition products.”
radio SoC extends ADI’s precision analog microcontroller portfolio, which now includes an
ultra-low-power offering based on the Cortex-M3 processor, to support the demanding design requirements of today’s
remote sensing and measurement applications. Design engineers can visit ADI’s
, an open technical support forum where they can ask questions, share knowledge and search for
answers to questions regarding precision analog microcontrollers. ADuCRF101 Lowers Power in a Wide
Range of Applications
The network range and coverage of the
radio SoC is well suited to applications where data must be captured, measured, and transmitted
quickly in noisy environments without taxing battery life.
radio SoC, ADI now gives energy metering customers the option of designing with their own processor
alongside ADI’s ISM-band transceivers or choosing a fully integrated SoC,” said Ronn Kliger, Energy Group
director, Analog Devices. “The new device is an important addition to our energy portfolio, which includes
products ranging from single- and poly-phase metering ICs to a variety of integrated RF transceivers. The
also delivers a single-chip communications solution for the challenging requirements of battery
powered gas, water and heat meters.”
In medical patient monitoring systems, a wireless Holter or telemetry monitor worn by the patient needs to
be small, operate at low power for extended battery life, and offer the performance level to sustain uninterrupted
communication of the patient’s vital signs. The
enables these applications and also provides a platform upon which patient monitoring outside of the
hospital environment can be done.
More About The ADuCRF101 Radio SoC
radio SoC’s 32-bit ARM Cortex-M3 core provides the throughput necessary to support a growing array
of sensing and measurement functions, and features serial download and debug, an external watch crystal that
functions as a wake-up timer, and a 16-MHz PLL with an 8-way programmable divider. The integrated RF transceiver
provides a combination of industry-leading interference blocking performance with very low receive and transmit
currents, allowing more robust operation in urban environments where interfering signals are present.
device is supported by a suite of ADI development tools, which include evaluation boards with
matching antennae, an emulator board,
-specific compiler, serial-wire program download and debug support, as well as CMSIS (Cortex
Microcontroller Software Interface Standard) compliant software libraries to support all peripherals. Also
available are a power/battery-life calculator and RF low-level drivers and evaluation tools.
radio SoC supports
a coalition of organizations promoting a standard for
versatile wireless sensor networks at 433 MHz that is based on the ISO-18000-7 standard (originally designed for
active RFID in the military). The
additionally boasts long range, good penetration and low power and also supports 802.15.4-based
networks. ADuCRF101 Radio SoC Key Features
As previously described, the ADuCRF101 is supported by a suite of evaluation boards for different frequencies
and input configurations. Visit the ADuCRF101 product page to learn more.
Complementary components for the
ADuCRF101 radio SoC include ADI’s integrated ISM band single-chip RF transceivers including the ADF7020, ADF7021,
ADF7022, ADF7023, ADF7025 and ADF7242.
