MAX71336SECD+T

Overview

The MAX71336SECD+T is a three-phase metering System on Chip (SoC) manufactured by Analog Devices Inc. under the Maxim Integrated brand. It integrates high-precision analog front-end circuitry with a microcontroller unit and memory subsystems designed for utility-grade energy measurement applications. The device features 512K bytes of flash memory and 48KB of RAM, supporting complex firmware implementations for advanced metering infrastructure. It operates within standard industrial temperature ranges and utilizes a 100-pin LQFP package to facilitate PCB integration in smart meter designs.

Feature Summary

• Integrates three-phase voltage and current measurement channels with dedicated analog-to-digital conversion capabilities.
• Includes embedded non-volatile flash memory and volatile RAM for secure data storage and real-time processing.
• Supports communication interfaces required for smart grid connectivity and remote meter reading systems.

Applications

• Three-phase smart electricity meters
• Industrial energy monitoring systems
• Utility-grade revenue metering equipment

Procurement Notes

Verify the manufacturer designation carefully, as sources list both Silergy and Analog Devices/Maxim Integrated for similar part numbers. Confirm the specific suffix 'T' indicates tape and reel packaging if required for automated assembly. Ensure compatibility with existing firmware environments before procurement, as legacy versions may have different memory configurations or pinouts.

Selection Notes

Select this component when designing three-phase metering solutions requiring integrated signal conditioning and digital processing. Compare against single-phase variants if system architecture allows. Verify that the 100LQFP package dimensions fit the mechanical constraints of the target enclosure. Ensure the available flash and RAM sizes meet the firmware requirements for local data logging and communication protocols.

Part Context

This component belongs to the MAX7133x series of metering SoCs, which are widely used in modern utility infrastructure. The series typically includes variants with differing memory capacities and interface options. The MAX71336 represents a higher-capacity configuration compared to lower-tier models like the MAX71335, offering enhanced storage for complex tariff structures and event logging.

Replacement Considerations

The MAX71335SECD+T is a related variant within the same family but typically features reduced memory capacity. Cross-referencing datasheets is essential to verify functional equivalence regarding pinout and peripheral availability before substitution.
