Overview
The 71M6521BE-IGTR/F is a System on a Chip (SoC) energy metering integrated circuit designed for single-phase and dual-phase residential applications. It integrates an 8-bit 80515 core with 8 kB of Flash program memory and 7 kB of data RAM. The device features a high-resolution 21-bit Analog-to-Digital Converter (ADC) for precise measurement. It operates within a supply voltage range of 3.3 V and supports industrial temperature ranges from -40°C to +85°C. Communication interfaces include I2C and UART protocols, facilitating integration into smart metering systems.
Feature Summary
- Integrates a dedicated 8-bit 80515 processor core with embedded non-volatile memory for standalone operation.
- Features a high-precision 21-bit ADC suitable for accurate energy metering in single-phase and dual-phase configurations.
- Supports standard digital communication protocols including I2C and UART for system connectivity.
Applications
- Single-phase residential energy metering
- Dual-phase energy metering systems
- Smart grid monitoring devices
Procurement Notes
Verify the specific suffix 'IGTR/F' to confirm lead-free packaging and tape-and-reel delivery format. Confirm that the component is sourced from Analog Devices Inc., which acquired Maxim Integrated, to ensure access to current technical documentation and support channels. Cross-reference the datasheet revision to match design requirements.
Selection Notes
Select this component when designing single or dual-phase meters requiring integrated processing and high-resolution analog conversion. The inclusion of an 80515 core reduces external microcontroller dependencies. Ensure the 3.3 V operating voltage aligns with the target system power architecture and that the LQFP-64 package fits the PCB layout constraints.
Part Context
This part belongs to the Teridian Semiconductor line, now under Analog Devices Inc./Maxim Integrated. It is part of the Single Converter Technology series, aimed at simplifying energy meter designs by combining analog front-end capabilities with digital processing on a single die. The device replaces discrete solutions by integrating ADC, MCU, and memory functions.
Replacement Considerations
Check for direct pin-compatible upgrades within the 71M65xx series from Analog Devices. Verify if newer revisions offer enhanced security features or updated firmware compatibility without altering the board layout.
