AVR32DU28-I/SP

Overview

The AVR32DU28-I/SP is an 8-bit microcontroller from the AVR DU family, featuring a 32 KB Flash memory and 4 KB SRAM. 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 utilizes a 28-pin SPDIP package and supports industrial temperature ranges from -40°C to +85°C.

Feature Summary

Integrates a hardware multiplier CPU running at up to 24 MHz with single-cycle I/O access.
Includes a USB 2.0 full-speed device-compliant interface for crystal-less operation via OSCHF tuning.
Features Program and Debug Interface Disable (PDID) for secure firmware protection against unauthorized access.

Applications

USB-enabled embedded systems requiring full-speed data transfer
Industrial control applications needing secure code execution
IoT devices utilizing low-power sleep modes and event systems

Procurement Notes

Verify the specific ordering suffix 'I/SP' corresponds to the Industrial temperature range (-40°C to +85°C) and the 28-pin SPDIP package style. Confirm that the preliminary datasheet status does not impact final production specifications before committing to design-in. Ensure compatibility with existing UPDI programming tools for development.

Selection Notes

Select this component when a balance of moderate Flash capacity and integrated USB connectivity is required within a PDIP form factor. The AVR DU family allows vertical migration to other pin counts without code modification. Consider the PDID feature if security against external debugging is a primary design constraint.

Part Context

This part belongs to the AVR® DU Family of microcontrollers, which are designed for flexible, low-power architectures. The family shares pin and feature compatibility across various pin counts and memory sizes, facilitating easy upgrades or downgrades in product designs without altering source code.

Replacement Considerations

AVR16DU28-I/SP offers 16 KB Flash; AVR64DU28-I/SP offers 64 KB Flash. Both maintain identical pinouts and peripheral sets for direct substitution if memory requirements differ.
