AVR64DU32-I/PT

Overview

The AVR64DU32-I/PT is an 8-bit microcontroller from the AVR DU family, featuring a 64 KB Flash memory, 8 KB SRAM, and 256 bytes of EEPROM. It operates at clock speeds up to 24 MHz with a supply voltage range of 1.8V to 5.5V. The device includes a USB 2.0 full-speed interface, two USARTs, one SPI, and one TWI/I2C controller. It provides up to 25 programmable GPIO pins in a TQFP-32 package.

Feature Summary

• Includes a USB 2.0 full-speed device-compliant interface for communication.
• Features Program and Debug Interface Disable (PDID) for firmware security.
• Supports read-while-write operations on Flash memory.

Applications

• USB-enabled embedded systems
• Industrial control applications
• Low-power sensor nodes

Procurement Notes

Verify that the datasheet version matches the specific revision required for your design. Confirm the package type is TQFP-32 as indicated by the suffix. Ensure the temperature grade corresponds to industrial specifications if operating in extreme environments.

Selection Notes

Select this model when 64 KB of program memory and 8 KB of data RAM are required. It is suitable for designs needing integrated USB connectivity without external transceivers. Consider pin count compatibility if migrating from smaller variants within the same family.

Part Context

This component belongs to the AVR DU family of microcontrollers. It shares architectural similarities with other devices in the series but offers higher memory capacity. The family supports vertical migration between different memory sizes while maintaining pin compatibility.
