AVR64DB64-E/PT

Overview

The AVR64DB64-E/PT is an 8-bit microcontroller from the AVR DB family, utilizing the AVR CPU with a hardware multiplier running at clock speeds up to 24 MHz. It features 64 KB of Flash memory, 8 KB of SRAM, and 512 bytes of EEPROM. The device is housed in a 64-pin TQFP package and supports a supply voltage range of 1.8V to 5.5V. It includes advanced peripherals such as a 12-bit ADC, three op amps, and multiple communication interfaces.

Feature Summary

• Features Multi-Voltage I/O (MVIO) on Port C for flexible input voltage threshold selection.
• Includes Analog Signal Conditioning (OPAMP) peripheral with internal resistor ladder configurations.
• Supports automated cyclic redundancy check (CRC) scanning for Flash program memory integrity.

Applications

• Real-time control systems requiring high-speed analog processing
• Sensor nodes with multi-voltage interface requirements
• Secondary safety monitoring equipment

Procurement Notes

Verify the 'E' suffix indicates extended temperature operation (-40°C to +125°C). Confirm the 'PT' suffix corresponds to the TQFP package style. Ensure the specific revision matches the required datasheet version DS40002300B for accurate electrical characteristics.

Selection Notes

Select this part for applications needing vertical migration within the AVR DB family without code modification. Consider the 64-pin count for maximum peripheral availability compared to smaller variants. Verify that the 24 MHz operating frequency meets the system timing requirements.

Part Context

This component belongs to the AVR64DB28/32/48/64 series, designed for flexible low-power architecture. It shares pin and feature compatibility across the family, allowing horizontal migration to reduce pin counts or vertical migration to increase them while maintaining software compatibility.

Replacement Considerations

AVR64DB64-I/PT offers identical specifications but operates within the industrial temperature range (-40°C to +85°C).
