AVR64DU28-I/SP

Overview

The AVR64DU28-I/SP is an 8-bit microcontroller from the AVR DU family, featuring a 24 MHz AVR CPU with hardware multiplier. It includes 64 KB of Flash memory, 8 KB of SRAM, and 256 bytes of EEPROM. The device operates within a supply voltage range of 1.8 V to 5.5 V and supports industrial temperatures from -40°C to +85°C. Key peripherals include a USB 2.0 full-speed interface, two USARTs, one SPI, one TWI/I2C, a 10-bit ADC, and an analog comparator. It utilizes a 28-pin SPDIP package.

Feature Summary

Integrated USB 2.0 full-speed device interface supporting crystal-less operation via OSCHF tuning.
Program and Debug Interface Disable (PDID) mechanism for secure firmware protection.
Configurable Custom Logic (CCL) with four programmable Look-up Tables (LUTs).
Event System enabling CPU-independent inter-peripheral signaling.

Applications

USB-enabled embedded control systems
Industrial communication nodes requiring RS-485 or LIN client support
Secure firmware upgrade applications utilizing PDID features

Procurement Notes

Verify component authenticity through authorized Microchip distributors. Confirm datasheet revision DS40002548A matches the delivered product. Ensure ordering suffixes align with specific package and temperature requirements. Request manufacturer certificates of conformity for quality assurance.

Selection Notes

Select this model for designs requiring integrated USB connectivity without external transceivers. Suitable for applications needing robust security features like PDID. Verify pin compatibility if migrating from other AVR DU variants. Consider power consumption profiles across different sleep modes.

Part Context

Part of the AVR DU family, offering vertical migration compatibility within the series. Designed for low-power applications with flexible architecture. Supports single-pin UPDI programming and debugging. Includes advanced digital peripherals and intelligent analog features.
