AVR64DU32T-I/PT

Overview

The AVR64DU32T-I/PT is an 8-bit microcontroller from the AVR DU family, featuring a 64 KB Flash memory, 8 KB SRAM, and 256 B EEPROM. It operates at clock speeds up to 24 MHz with a supply voltage range of 1.8 V to 5.5 V. The device includes a USB 2.0 full-speed device interface, two USARTs, one SPI, and one TWI/I2C peripheral. It utilizes a TQFP-32 package and supports industrial temperature ranges from -40°C to +85°C.

Feature Summary

Supports genuine read-while-write operation for in-system self-programmable Flash memory.
Includes a USB 2.0 full-speed device-compliant interface with multipacket transfer capabilities.
Features Configurable Custom Logic (CCL) with four programmable Look-up Tables (LUTs).
Provides Program and Debug Interface Disable (PDID) for secure firmware protection.

Applications

USB-enabled embedded applications requiring crystal-less operation via OSCHF tuning.
Industrial control systems utilizing the Event System for inter-peripheral signaling.
Secure firmware upgrade implementations using Boot Code section protection.
Low-power designs leveraging multiple sleep modes and automated CRC Flash scans.

Procurement Notes

Verify that the specific ordering suffix 'T' corresponds to the Tape & Reel carrier type as defined in the datasheet nomenclature. Confirm the 'I' suffix indicates the Industrial temperature range (-40°C to +85°C). Ensure the package style matches the required TQFP form factor for your PCB layout constraints before finalizing procurement.

Selection Notes

Select this component when 64 KB of Flash and 8 KB of SRAM are required within a 32-pin footprint. It is suitable for designs needing integrated USB connectivity without external transceivers. Consider the 1.8 V to 5.5 V operating range for flexible power supply architectures. Verify pin compatibility if migrating from smaller AVR DU variants like the AVR32DU32.

Part Context

This part belongs to the AVR® DU Family, which shares pin and feature compatibility across vertical migrations. The AVR64DU32 represents the highest memory configuration in the 32-pin variant lineup. It integrates the AVR CPU with a hardware multiplier and advanced digital peripherals, positioning it for cost-sensitive applications requiring robust I/O and communication interfaces.
