71M6545-IGTR/F

Overview

The 71M6545-IGTR/F is a three-phase energy metering integrated circuit from the Single Converter Technology series. It features a 64-LQFP package measuring 10x10 mm. The device operates on a supply voltage range of 3 V to 3.6 V with an I/O high voltage of 2 V. It includes 64K flash memory and achieves a measurement error of 0.1%. The component is classified as discontinued.

Applications

• Three-phase energy metering systems
• Power sequencing applications
• Voltage monitoring circuits

Procurement Notes

This component is officially listed as discontinued by Analog Devices Inc./Maxim Integrated. Distributors such as DigiKey and Mouser confirm it is no longer carried or available for new orders. Verification of current stock status through authorized channels is required, though availability is highly unlikely due to the obsolescence notice.

Selection Notes

Engineers should evaluate this part only if existing designs require exact compatibility with the Single Converter Technology architecture. Due to its discontinued status, alternative components with similar metrology accuracy and interface requirements must be identified. Reviewing the manufacturer's product change notices is essential before finalizing any design that might rely on this obsolete silicon.

Part Context

The 71M6545-IGTR/F belongs to the Metrology Systems on a Chip (SoC) family designed for precise power measurement. It integrates necessary analog-to-digital conversion and digital signal processing capabilities into a single package. The 64-LQFP form factor allows for compact PCB layouts in industrial and utility metering equipment requiring high accuracy.

Replacement Considerations

No public confirmed substitute part numbers are provided in the source material. Designers must consult Analog Devices technical support for qualified replacements compatible with the 64-LQFP footprint and 0.1% accuracy specifications.
