Teridian's SOC solutions for power metering have helped fuel the utility industry's migration to solid state metering, while simultaneously driving down costs and improving anti-tampering capabilities. Teridian Power Meter ICs offer the highest level of integration and flexibility in the industry and are ideal for developing low cost, intelligent utility meters for residential and industrial applications.

For example, the 71M6511 is a highly integrated SOC that combines a microprocessor core, Real Time Clock (RTC), FLASH memory and LCD driver. Teridian's patent pending Single Converter Technology^TM with a 22-bit delta-sigma ADC, 3 analog inputs, digital temperature compensation, precision voltage reference and 32-bit computation engine supports a wide range of residential metering applications with very few low cost external components.

For poly-phase metering applications, Teridian's advanced 71M6513 leverages the Single Converter Technology^TM and above capabilities along with a 21-bit 2nd order delta-sigma ADC and 6 analog inputs. Poly-phase monitoring enables the collection of a much richer set of information, beyond just how much electricity is used. In addition to enabling an assessment of power efficiency, which is important for industrial applications, poly-phase also provides improved security to detect tampering and/or power theft. Anti-tamper and time-of-use billing are both key features that are derived from an integrated 'real time clock' which enhances value while simultaneously saving on BOM costs. Anti-tampering capabilities are becoming especially important in developing countries, such as China and India, where power usage and power theft are both growing rapidly.
