AVR128DA64ST-I/5LX

Overview

The AVR128DA64ST-I/5LX is an 8-bit microcontroller from the AVR DA(S) family, featuring a 128 KB Flash memory, 16 KB SRAM, and 512B EEPROM. It operates at up to 24 MHz with a supply voltage range of 1.8V to 5.5V. The device includes a 12-bit differential ADC with 22 channels, three analog comparators, three zero-cross detectors, and a Peripheral Touch Controller (PTC). It supports industrial temperature ranges (-40°C to +85°C) and utilizes a VQFN48 package.

Feature Summary

Features Program and Debug Interface Disable (PDID) for secure firmware upgrades and authentication.
Includes an Event System for CPU-independent inter-peripheral signaling.
Integrates a Peripheral Touch Controller (PTC) with Driven Shield+ technology.
Supports single-pin Unified Program and Debug Interface (UPDI).

Applications

Secure firmware upgrade implementations
Capacitive touch button and slider interfaces
Industrial control systems requiring high I/O counts

Procurement Notes

Verify the specific ordering suffix 'ST' corresponds to Tape & Reel packaging and '5LX' indicates the VQFN48 package style as defined in the datasheet nomenclature. Confirm that the 'I' suffix matches the required -40°C to +85°C industrial temperature range for your application environment before finalizing procurement.

Selection Notes

Select this component when vertical migration within the AVR DA(S) family is required without code modification. It is suitable for designs needing up to 55 programmable I/O pins and advanced analog peripherals like the PTC and ZCD. Ensure the VQFN48 package dimensions fit the PCB layout constraints.

Part Context

This part belongs to the AVR128DA28/32/48/64(S) series, which are fully pin and feature compatible across the family. The 'S' designation indicates the inclusion of the PDID security feature. Devices allow horizontal migration to reduce pin counts or vertical migration to increase features while maintaining software compatibility.

Replacement Considerations

AVR128DA64-E/5LX offers extended temperature range (-40°C to +125°C). AVR128DA64T-I/PT provides the same core specifications but in a TQFP-64 package instead of VQFN48.
