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.
