AVR128DB64T-E/PT

Overview

The AVR128DB64T-E/PT is an 8-bit microcontroller from the AVR DB family, featuring a 24 MHz AVR CPU with hardware multiplier. It includes 128 KB of Flash memory, 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 TQFP package.

Feature Summary

• Features Multi-Voltage I/O (MVIO) on Port C for flexible voltage threshold selection.
• Includes advanced analog subsystems such as a 12-bit differential ADC, three analog comparators, and a 10-bit DAC.
• Supports CPU-independent inter-peripheral signaling via the Event System.
• Integrates Configurable Custom Logic (CCL) with programmable Look-up Tables.

Applications

• Industrial control systems requiring robust analog signal conditioning
• Power management applications utilizing zero-cross detection and PWM timers
• Smart energy devices and sensors operating across wide temperature ranges

Procurement Notes

Verify that the ordering suffix 'T' corresponds to tape-and-reel packaging rather than tray packaging when sourcing components. Confirm the '-E' suffix indicates the extended temperature rating of -40°C to 125°C. Ensure compatibility with the specific pinout and peripheral configuration required for your design implementation.

Selection Notes

Select this model for designs requiring high I/O counts and extensive analog peripherals within a 64-pin footprint. It offers vertical migration compatibility with other AVR DB family members without code modification. Consider the Event System and CCL capabilities if reducing CPU load through peripheral automation is necessary.

Part Context

This component belongs to the AVR128DB28/32/48/64 series, which shares a unified architecture across varying pin counts and memory sizes. The AVR DB family emphasizes low-power performance and industry-leading EMI/EMC robustness. It utilizes the Unified Program and Debug Interface (UPDI) for simplified programming and debugging workflows.
