AVR128DA32-I/PT

Overview

The AVR128DA32-I/PT 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 industrial temperatures from -40°C to +85°C. It provides up to 27 general-purpose I/O pins in a 32-pin TQFP package.

Feature Summary

Integrates intelligent analog features including a 12-bit differential ADC, three analog comparators, and zero-cross detectors for precise signal conditioning.
Supports capacitive touch applications via the Peripheral Touch Controller (PTC) with Driven Shield+ technology.
Enables flexible inter-peripheral communication through the Event System and Configurable Custom Logic (CCL).
Features a single-pin Unified Program and Debug Interface (UPDI) for simplified programming and debugging.

Applications

Smart home appliances requiring multi-voltage I/O and analog signal processing
Industrial control systems utilizing real-time monitoring and event-driven logic
Consumer electronics incorporating capacitive touch interfaces

Procurement Notes

Verify that the ordering suffix 'I' corresponds to the industrial temperature range (-40°C to +85°C) and 'PT' indicates the TQFP package. Confirm the specific revision level against the manufacturer's datasheet DS40002183B to ensure compatibility with your design requirements.

Selection Notes

Select this component when vertical migration within the AVR DA family is required without code modification. It is suitable for designs needing high memory density combined with advanced analog peripherals and low-power sleep modes.

Part Context

This part belongs to the AVR128DA28/32/48/64 series, which shares pin and feature compatibility across different pin counts. It utilizes the latest AVR architecture technologies, offering a balance of performance and power efficiency for embedded applications.
