78M6612
Single-Phase, Dual-Outlet
Power and Energy Measurement IC
DATA SHEET
DS_6612_001
DESCRIPTION
The Teridian? 78M6612 is a highly integrated, single-phase,
power and energy measurement and monitoring system-on-
chip (SoC) that includes a 32-bit compute engine (CE), an
MPU core, RTC, and flash. Our Single Converter
Technology ? with a 22-bit delta-sigma ADC, four analog
inputs, digital temperature compensation, and precision
voltage reference supports a wide range of single-phase,
dual-outlet power measurement applications with very few
external components.
With measurement technology leveraged from Maxim’s flagship
utility metering ICs, the device offers features including 32 KB
of flash program memory, 2 KB shared RAM, three low-power
modes with internal timer or external event wake-up, two
UARTs, I 2 C/MICROWIRE? EEPROM I/F, and an in-system
programmable flash. Complete outlet measurement unit (OMU)
and AC power monitor (AC-PMON) firmware is available or can
be preloaded into the IC.
A complete array of ICE and development tools, programming
libraries and reference designs enable rapid development and
certification of power and energy measurement solutions that
meet the most demanding worldwide electricity metering
standards.
