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-
up, 2 UARTs , I2C/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.
