Energy Meter ICs
DATA SHEET
GENERAL DESCRIPTION
The Teridian™ 71M6533 and 71M6534 are third-generation
polyphase metering systems-on-chips (SoCs) with a 10MHz 8051-
compatible MPU core, low-power RTC, flash, and LCD driver. The
Single Converter Technology® with a 22-bit delta-sigma ADC, seven
analog inputs, digital temperature compensation, precision voltage
reference, and a 32-bit computation engine (CE) supports a wide
range of metering applications with very few external components.
The 71M6533 and 71M6534 add several new features to the
Teridian flagship 71M6513 polyphase meters, including an SPI
interface, advanced power management with < 1µA sleep current,
4KB shared RAM, and 128KB (71M6533/H, 71M6534), or 256KB
(71M6533G, 71M6534H) flash, which can be programmed in the
field with new code and/or data during meter operation. Higher
processing and sampling rates and larger memory offer a
powerful metering platform for commercial and industrial meters
with up to class 0.2 accuracy.
A complete array of ICE and development tools, programming
libraries and reference designs enable rapid development and
certification of meters that meet all ANSI and IEC electricity metering
standards worldwide.
