AVR32DA32ST-E/QZB

Overview

The AVR32DA32ST-E/QZB is an 8-bit microcontroller from the AVR DA family, featuring a 32 KB Flash memory, 4 KB SRAM, and 512 B EEPROM. It operates at up to 24 MHz with a supply voltage range of 1.8 V to 5.5 V. The device includes a 12-bit ADC, three analog comparators, a DAC, and a Peripheral Touch Controller. It utilizes a QFN package and supports extended temperature operation.

Feature Summary

Supports Program and Debug Interface Disable (PDID) for secure firmware protection
Integrates a Peripheral Touch Controller with Driven Shield+ technology
Features an Event System for CPU-independent peripheral signaling

Applications

Industrial control systems requiring real-time processing
IoT devices needing low-power operation and touch interfaces
Automotive applications within extended temperature ranges

Procurement Notes

Verify the specific ordering suffix 'VAO' indicates automotive qualification status. Confirm the package style 'QZB' corresponds to the correct pin count and dimensions. Ensure the temperature grade 'E' matches the required operational environment specifications before finalizing procurement.

Selection Notes

Select this model when 32 KB of program memory is sufficient for the application logic. Choose the E-temperature variant for environments exceeding standard industrial limits. Verify that the QFN package fits the available PCB footprint constraints compared to TQFP or SSOP alternatives.

Part Context

This component belongs to the AVR DA(S) family, which offers vertical migration compatibility across different memory sizes. It shares architectural features with the AVR64DA and AVR128DA series, allowing code reuse while adjusting for specific memory and I/O requirements.
