AVR128DB64T-E/MR

Overview

The AVR128DB64T-E/MR is an 8-bit microcontroller from the AVR DB family, featuring a 24 MHz AVR CPU with hardware multiplier. It includes 128 KB of self-programmable Flash, 16 KB of SRAM, and 512 bytes of EEPROM. The device operates within a supply voltage range of 1.8V to 5.5V and supports industrial (-40°C to 85°C) and extended (-40°C to 125°C) temperature ranges. It provides up to 55 programmable I/O pins in a 64-pin QFN package.

Feature Summary

Features multi-voltage I/O (MVIO) on Port C for flexible interface compatibility.
Includes advanced analog subsystems such as a 12-bit differential ADC and op-amps.
Supports CPU-independent peripheral signaling via the Event System.
Integrates Configurable Custom Logic (CCL) with Look-up Tables.

Applications

Industrial control systems requiring robust analog signal conditioning
Power management applications utilizing zero-cross detectors
Smart energy metering devices
Motor control implementations

Procurement Notes

Verify the specific suffix 'E' indicates the extended temperature range capability (-40°C to 125°C). Confirm the 'MR' suffix corresponds to the tape and reel packaging format required for automated assembly processes. Ensure the ordering code matches the exact pin count and memory configuration specified in the official datasheet.

Selection Notes

Select this component when high I/O density and advanced analog features are required in a compact 64-pin form factor. Consider the vertical migration path within the AVR DB family if future design changes necessitate different pin counts without code modification. Evaluate the extended temperature rating against environmental operating conditions.

Part Context

This part belongs to the AVR128DB28/32/48/64 series, which shares a common architecture and instruction set. Devices within this family offer full pin and feature compatibility, allowing for horizontal migration by reducing pin counts or vertical migration by increasing them while maintaining software compatibility.
