Procurement Notes

Verify the specific suffix requirements for the 71M6515H-IGTR/F variant against official datasheets to ensure correct packaging and temperature grade compatibility. Confirm availability status as distribution channels may report limited stock or discontinuation notices. Cross-reference the manufacturer part number with authorized distributor catalogs to validate authenticity and traceability before procurement.

Selection Notes

Select this component when designing single-phase metering applications requiring high accuracy and integrated processing capabilities. The combination of a 22-bit ADC and 32-bit CE reduces external component count compared to discrete solutions. Ensure the design accommodates the LQFP-100 package footprint and 3.3 V power domain constraints during PCB layout.

Part Context

This SoC belongs to the Teridian 71M6x01 family of fourth-generation single-phase metering devices. These chips are engineered to support various metering applications with minimal external components. The family emphasizes low power consumption and compliance with international metrology standards, serving as a foundational platform for modern utility metering hardware.

Replacement Considerations

Consult official documentation for confirmed substitute part numbers within the 71M6x01 series. Verify pinout and register compatibility before substituting with other variants in the same product family.
