MAX71315SECD+

Overview

The MAX71315SECD+ is a single-phase metering System on Chip (SoC) manufactured by Silergy, part of the MAX71315 series. It integrates a MAXQ30 user MPU core with 256 KB Flash and 21 KB SRAM. The device supports poly and single-phase metering applications with an accuracy of ±0.1% over a 5000:1 range. It features sensor inputs for current and voltage, supporting CT, shunt, and Rogowski coil sensors. Additional integrated peripherals include a Real-Time Clock (RTC), multiple UART interfaces, GPIOs, and hardware encryption capabilities.

Feature Summary

• Integrates a MAXQ30 microprocessor core for flexible application development
• Provides high-precision energy measurement with ±0.1% accuracy
• Supports diverse current sensing technologies including CT, shunt, and Rogowski coils
• Includes built-in hardware encryption modules for secure data handling

Applications

• Single-phase electricity metering systems
• Poly-phase metering applications
• Smart grid monitoring devices
• Energy management subsystems requiring high accuracy

Procurement Notes

Verify the manufacturer designation carefully, as this component is listed under Silergy in official distributor catalogs despite the brand query referencing Analog Devices/Maxim Integrated. Confirm the specific suffix 'SECD+' matches the required package and temperature grade. Ensure that the ordering information aligns with the Silergy product line rather than Maxim Integrated specifications to avoid procurement errors due to corporate acquisition history.

Selection Notes

Select this SoC when a combined processing and metering solution is required for single-phase applications. The integration of the MAXQ30 core allows for complex firmware execution alongside precise analog measurements. Consider the available Flash and SRAM sizes for application complexity. Verify compatibility with the desired sensor types, such as Rogowski coils or shunts, based on the supported input configurations.

Part Context

This component belongs to the MAX71315 family of metering SoCs. It is distinct from other Maxim Integrated products like the MAX71335 or MAX7315, which serve different functions such as discontinued variants or peripheral I/O expansion. The MAX71315 series focuses specifically on integrating metering front-ends with embedded processing cores for utility metering applications.
