Overview
The 78M6610+LMU/D01T is a single-phase energy measurement processor system-on-chip (SoC) manufactured by Analog Devices Inc./Maxim Integrated. It features an Energy Measurement Processor (EMP) core with a maximum clock frequency of 20 MHz. The device includes 8 kB of Flash program memory and 1.5 kB of internal RAM. It operates on a 3.3 V supply voltage within a temperature range of -40°C to +85°C. Communication interfaces include I2C, SPI, and UART. The component is housed in a QFN-24 package.
Feature Summary
- Integrates an EMP core for dedicated signal processing without a user MPU
- Supports multiple digital communication protocols including I2C, SPI, and UART
- Includes on-chip temperature sensor and flexible oscillator options
Applications
- Single-phase energy metering systems
- Power supply unit (PSU) monitoring
- DC power measurement applications
Procurement Notes
Verify component status as the listing indicates discontinued availability at major distributors. Confirm lead times and alternative sourcing channels due to limited supply constraints. Ensure compatibility with existing firmware and hardware designs before procurement. Check RoHS compliance details via official documentation.
Selection Notes
Select this component for single-phase applications requiring dedicated energy measurement processing. Consider the absence of an integrated ADC and reliance on external sensors. Evaluate interface requirements against available I2C, SPI, and UART options. Assess memory constraints of 8 kB Flash and 1.5 kB RAM for application complexity.
Part Context
This part belongs to the 78M6610 series of metering SoCs designed for precise energy measurement. It utilizes Teridian's Single Converter Technology principles adapted for single-phase use. The series targets utility and industrial metering markets requiring high accuracy and low power consumption.
Replacement Considerations
Check for 78M6610+LMU/B01 or 78M6610+PSD variants as potential functional substitutes within the same family. Verify pinout and software compatibility when considering cross-package replacements.
