AVR128DA48ST-E/6MX

Overview

The AVR128DA48ST-E/6MX is an 8-bit microcontroller from the AVR DA(S) family, featuring a 48-pin VQFN package. It operates at up to 24 MHz and includes 128 KB of Flash memory, 16 KB of SRAM, and 512 B of EEPROM. The device supports extended temperature ranges (-40°C to +125°C) and integrates advanced peripherals such as a Peripheral Touch Controller (PTC), 12-bit ADC, and Programmable Digital Interface Disable (PDID).

Feature Summary

Integrates a Peripheral Touch Controller (PTC) with Driven Shield+ technology for capacitive touch applications.
Includes Program and Debug Interface Disable (PDID) for secure firmware protection against unauthorized access.
Features intelligent analog components including a 12-bit differential ADC and multiple voltage references.

Applications

Wired and wireless communication stacks requiring high memory density.
Smart home devices utilizing capacitive touch interfaces.
Industrial control systems operating in extended temperature environments.

Procurement Notes

Verify the specific ordering suffixes to confirm the package style, temperature range, and carrier type match your design requirements. Ensure that the PDID feature is enabled if security constraints are required. Cross-reference the datasheet revision to confirm peripheral availability and electrical characteristics.

Selection Notes

Select this model for designs requiring vertical migration within the AVR DA family without code modification. Consider the 48-pin form factor for balanced I/O count and board space. Evaluate the need for the extended temperature rating and PDID security features compared to industrial variants.

Part Context

This component belongs to the AVR128DA28/32/48/64(S) series, which offers pin-compatible upgrades across different pin counts. The 'S' designation indicates the inclusion of the PDID security feature. The device shares architectural similarities with other AVR DA family members, allowing for flexible hardware scaling.
