AVR128DA28-I/SP

Overview

The AVR128DA28-I/SP is an 8-bit microcontroller from the AVR DA family, featuring a 24 MHz AVR CPU with hardware multiplier. It includes 128 KB of Flash memory, 16 KB of SRAM, and 512 B of EEPROM. The device operates within a supply voltage range of 1.8 V to 5.5 V and supports an industrial temperature range of -40°C to +85°C. It provides 23 general-purpose I/O pins in a 28-pin SPDIP package.

Feature Summary

Integrates intelligent analog peripherals including a 12-bit differential ADC, 10-bit DAC, and three analog comparators for precise signal conditioning.
Supports capacitive touch applications via the Peripheral Touch Controller (PTC) with Driven Shield+ technology.
Features a single-pin Unified Program and Debug Interface (UPDI) for simplified programming and debugging workflows.

Applications

Industrial control systems requiring real-time processing
Smart energy metering and monitoring devices
Consumer appliances with user interface controls

Procurement Notes

Verify the specific ordering suffix against official Microchip documentation to confirm package type and temperature rating. Ensure compatibility with existing design constraints before procurement. Confirm RoHS compliance status through current manufacturer declarations.

Selection Notes

Select this component when vertical migration within the AVR DA family is required without code modification. Consider the 28-pin constraint if fewer I/O resources are sufficient compared to higher pin-count variants.

Part Context

This part belongs to the AVR128DA28/32/48/64 series, designed for low-power performance and real-time control. The family offers flexible architecture with event systems and advanced digital peripherals suitable for communication stack-intensive functions.
