AVR128DA64-I/PT

Overview

The AVR128DA64-I/PT is an 8-bit microcontroller from the AVR® DA family, manufactured by Microchip Technology. It features a 24 MHz AVR CPU with hardware multiplier and operates within a supply voltage range of 1.8V to 5.5V. The device includes 128 KB of self-programmable Flash memory, 16 KB of SRAM, and 512B of EEPROM. It is housed in a 64-pin TQFP package (10x10 mm) and supports industrial temperature ranges from -40°C to +85°C.

Feature Summary

Integrates intelligent analog peripherals including a 12-bit differential ADC, three analog comparators, and a Peripheral Touch Controller for capacitive sensing applications.
Supports high-speed communication through up to six USARTs, two SPI interfaces, and dual-mode TWI/I2C controllers.
Features a flexible Event System for CPU-independent inter-peripheral signaling and Configurable Custom Logic (CCL) using Look-up Tables.

Applications

Wired and wireless communication stack implementations
Capacitive touch interface designs for buttons, sliders, or wheels
Power control systems utilizing Timer/Counter Type D

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 style. Confirm the datasheet revision matches the specific manufacturing lot requirements. Ensure compatibility with UPDI programming tools for development and debugging.

Selection Notes

Select this component when vertical migration within the AVR DA family is required without code modification. Choose this part over lower pin-count variants if the design requires up to 55 general-purpose I/O pins and access to all peripheral channels available in the 64-pin configuration.

Part Context

This device belongs to the AVR128DA series, which shares full pin and feature compatibility with other members of the AVR® DA family. It offers horizontal migration options to smaller packages like the 28-, 32-, or 48-pin variants, allowing designers to reduce pin counts while maintaining software compatibility.
