71M6545HT-IGT/F

Overview

The 71M6545HT-IGT/F is a metrology System on Chip (SoC) manufactured by Silergy, part of the 71M6543HT series. It integrates an 80515 core with a maximum clock frequency of 5 MHz. The device features a 22-bit ADC resolution, 5 kB data RAM, and 64 kB program memory. It operates at a supply voltage of 3.3 V and provides 29 I/O pins within an LQFP-64 package. Communication interfaces include I2C and UART.

Feature Summary

• Integrates high-resolution 22-bit analog-to-digital conversion for precise metering applications
• Combines processing capabilities with dedicated metrology functions in a single chip architecture
• Supports standard digital communication protocols for system integration

Applications

• Single-phase energy metering systems
• Smart meter infrastructure development
• Precision power monitoring devices

Procurement Notes

Verify the manufacturer designation carefully, as this specific part number is attributed to Silergy rather than Analog Devices or Maxim Integrated in available documentation. Confirm the exact suffix requirements and packaging options such as Reel or Cut Tape directly with the supplier to ensure compatibility with your assembly process and regional availability constraints.

Selection Notes

Select this component when a compact SoC solution is required that combines processing logic with high-precision analog measurement capabilities. The 22-bit ADC resolution makes it suitable for applications demanding accurate energy consumption tracking. Ensure the design accommodates the LQFP-64 footprint and utilizes the available I2C and UART interfaces for configuration and data retrieval.

Part Context

This device belongs to the 71M6543HT family of metrology processors. It shares architectural similarities with other members like the 71M6545T-IGT/F but may differ in specific thermal or performance characteristics indicated by the HT suffix. It serves as a specialized processor for utility metering applications requiring integrated signal conditioning and digital processing.

Replacement Considerations

The 71M6545T-IGT/F is a closely related variant within the same series. Verify pinout compatibility and specific functional differences before substitution. No other direct public substitutes are confirmed.
