New Energy Metering Solutions Launched

Analog Devices (ADI) is expanding its portfolio of energy metering solutions with the ADE51xx and ADE55xx single-chip metering devices. These are designed for the 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 kbs of on-chip flash memory and 2 kbs of RAM, 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), 2 UARTs (universal asynchronous receivers-transmitters), and intelligent battery management technology.

In battery mode, current consumption is said to be reduced to 1.5 microamps. The ADE51xx differs from the ADE55xx by offering 2 current inputs for anti-tampering detection and billing.

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 US $3.49 per unit in 1,000-piece quantities.
