DESCRIPTION

The Teridian 78M6612 is a highly integrated,

single-phase, power and energy measurement and

monitoring SOC which includes a 32-bit compute engine

(CE), an MPU core, RTC, and Flash. The Teridian

patented Single

Converter Technology

® with a 22-bit delta-sigma ADC, 4

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 Teridian’s

flagship utility metering IC’s it offers features including

32 KB of Flash program memory, 2 KB shared RAM, three

low power modes with internal timer or external event wake-

OPTIONAL

C/Micro wire 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 pre-loaded 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.
