Analog Devices Expands Energy Metering Portfolio to Address Advanced,
Emerging Monitoring Applications
- ADE51xx and ADE55xx system-on-chip energy metering solutions
increase RAM and program memory to serve more demanding global metering
communications protocols.
NORWOOD, Mass. (Business Wire EON) April 22, 2008 --
Analog Devices, Inc. (ADI) is expanding its portfolio of market-leading energy
metering solutions with the ADE51xx and ADE55xx single-chip metering
devices, which are designed for the increasingly sophisticated
communications networks used by today’s energy
markets. Globally, solid-state energy meters are replacing failure-prone
electromechanical systems, which are subject to meter tampering and
cannot easily support new features such as remote meter-reading and
time-of-use billing. These new features and the more robust metering
networks they enable are demanding greater memory density to handle the
energy industry’s growing data volume. Analog
Devices’ new SoC (system-on-chip) energy meter
devices feature 62 Kbytes of on-chip flash memory and 2 Kbytes of RAM
(random access memory), which provides more usable memory than any other
available energy meter to support the program and data storage needs of
advanced communications protocols in North America, Europe and emerging
Asian markets.
The single-chip ADE51xx and ADE55xx metering devices integrate a proven
energy measurement core, an 8051 microcontroller, a LCD (liquid crystal
display) driver with contrast control, a full hardware RTC (real-time
clock), two UARTs (universal asynchronous receivers-transmitters), and
intelligent battery management technology. In addition to replacing six
discrete ICs with a single SoC, the highly integrated metering solutions
maintain accurate time, sense temperature changes, run the LCD read-out,
and perform other critical system functions, all while using less than
half the power of competitive solutions. In battery mode, current
consumption is reduced to 1.5 microamps. This 50 percent reduction in
current consumption when the LCD is activated, as compared to other
energy metering SoC solutions, is achieved through a combination of
battery management techniques that allow the meter to run multiple LCD
screens, maintain active temperature measurement, and keep accurate
timing during power outages—all while the
microcontroller remains in sleep mode. The ADE51xx differs from the
ADE55xx by offering two current inputs for anti-tampering detection and
billing.
“When Linyang investigated export
opportunities, we realized that producing a cost-effective system
required a metering SoC capable of supporting the program size necessary
to implement multi-tariff tables and communication protocol while
providing a solution to our low-power needs,”
said M. Lu, chief engineer at Chinese energy meter manufacturer, Linyang
Electronics. “Analog Devices’
ADE55xx and ADE51xx devices not only increase the usable program size
above the current standard, they also push battery-mode functionality to
new heights with an internal battery switch, a full RTC with automatic
temperature curvature compensation, and four LCD screen memories with
automatic scrolling. These features make the ADE55xx and ADE51xx a
unique match to our metering needs.”
Availability and Pricing
The ADE5169 and ADE5569 energy meters are sampling now, with full
production scheduled for September 2008. The devices are available in
64-lead LQFP (low-profile quad flat-pack) packages and are priced at
$3.49 per unit in 1,000-piece quantities. For more information, visit www.analog.com/pr/ADE5169

Analog Devices in Energy Measurement
With more than 225 million energy meters using ADI’s
technology deployed worldwide, Analog Devices has delivered more energy
measurement solutions than any other semiconductor company. Superior in
quality, reliability, and performance, Analog Devices’
ADE energy metering ICs combine analog-to-digital converters (ADCs) with
fixed-function digital signal processors (DSPs) to perform critical
measurements, while providing unparalleled functionality and
ease-of-use. Analog Devices offers a broad range of semiconductor
solutions that solve design challenges in every aspect of metering
systems, including energy measurement; data and power management; user
interface; and RF, GSM/GPRS, and power line carrier communication
solutions. Analog Devices’ ADE ICs are ideal
for measuring watts (kWh), reactive energy (VAR), RMS and power quality
with the highest accuracy in single-phase and polyphase revenue meters
and industrial instruments. Analog Devices also offers its proprietary
brand of single- and polyphase energy metering chipsets and DSP-based
metering engines as complete, licensable solutions. For more
