AVR128DA64T-E/PT

Overview

The AVR128DA64T-E/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 Flash memory, 16 KB of SRAM, and 512B of EEPROM. It is housed in a 64-pin TQFP package (suffix PT) and supports extended industrial temperature ranges (-40°C to +125°C).

Feature Summary

Supports vertical migration across the AVR DA family without code modification due to full pin and feature compatibility.
Integrates intelligent analog peripherals including a 12-bit differential ADC, three analog comparators, and zero-cross detectors.
Features a Peripheral Touch Controller (PTC) utilizing Driven Shield+ technology for capacitive touch applications.
Includes a dedicated Event System for CPU-independent inter-peripheral signaling and configurable custom logic.

Applications

Wired and wireless communication stack implementations requiring high memory density.
Capacitive touch interfaces such as buttons, sliders, wheels, and 2D surfaces.
Power control systems utilizing optimized Timer/Counter type D peripherals.
Applications requiring real-time control combined with low-power operation.

Procurement Notes

Verify that the ordering suffix 'E' corresponds to the extended temperature range (-40°C to +125°C) rather than the standard industrial range ('I'). Confirm the 'T' suffix indicates tape and reel packaging. Ensure the 'PT' designation matches the required 64-pin TQFP physical footprint for your PCB layout.

Selection Notes

Select this component when the design requires 128 KB of program memory and up to 55 programmable I/O pins. It is suitable for projects needing advanced analog capabilities like differential ADCs and multiple zero-cross detectors. Consider this part if horizontal migration to lower pin counts is not required, as it offers the maximum peripheral count in the series.

Part Context

This device belongs to the AVR128DA28/32/48/64 series, which shares a common architecture but varies in pin count and memory size. The 64-pin variant provides the highest number of General Purpose I/Os and peripheral channels within the 128 KB Flash class. It serves as the top-end option for the AVR DA family regarding connectivity and analog resources.
