DESCRIPTION

The Teridian™ 78M6631 is a highly integrated 3-phase

power measurement and monitoring system-on-chip

(SoC), with a 10 MHz 8051-compatible MPU core and

Single Converter Technology® containing a 22-bit delta-

sigma converter and 32-bit compute engine (CE). The

78M6631 has been designed specifically for a wide

variety of applications requiring 3-phase power and

quality measurements. It supports both Delta and Wye

configurations.

At the measurement interface, the device provides six

analog inputs including three differential current and three

voltage for interfacing to current and voltage sensors. The

device provides better than 0.5% accuracy over a wide

2000:1 dynamic range.

The integrated MPU core and 128 KB of flash memory

provide

processing, data formatting, interfacing to host processor

via a UART or SPI interface, or using DIO pins for LEDs

or relay control. Complete firmware is available from

Maxim

manufacturing test.
