MAX71335LECQ+

Overview

The MAX71335LECQ+ is a System-on-Chip (SoC) designed for three-phase energy metering applications. It integrates a microcontroller unit with 256K of flash memory and operates within a 100-LQFP package measuring 14x14 mm. The device achieves a consistent 0.1% meter measurement error under normal operating conditions, ensuring accuracy suitable for billing-grade energy monitoring systems.

Feature Summary

• Integrates a system-on-chip architecture combining processing capabilities with non-volatile storage for efficient energy metering solutions.
• Provides high-precision measurement performance with a verified 0.1% error rate, supporting billing-grade accuracy requirements.
• Supports three-phase metering configurations through dedicated integrated circuit design.

Applications

• Billing-grade energy monitoring systems
• Three-phase electricity meters
• Smart grid infrastructure components

Procurement Notes

Verify the specific suffix 'LECQ+' to confirm the 100-LQFP package variant and commercial temperature range. Confirm RoHS compliance status as indicated in official documentation. Check current lifecycle status, as availability may vary between active and discontinued states across different distributors. Ensure the source document explicitly lists this part number to avoid confusion with similar variants.

Selection Notes

Select this component when designing three-phase metering systems requiring integrated flash memory and high measurement accuracy. The 100-LQFP package offers a compact footprint for PCB layout. Consider the 0.1% measurement error specification if billing-grade precision is mandatory. Verify that the integrated SoC architecture meets the processing requirements for local data handling without external controllers.

Part Context

This component belongs to the MAX71335 family of power management and metering ICs from Maxim Integrated, now part of Analog Devices Inc.
