AVR128DA32S-E/QZB

Overview

The AVR128DA32S-E/QZB is an 8-bit microcontroller from the AVR DA(S) family, featuring a 24 MHz AVR CPU with hardware multiplier. It includes 128 KB of Flash memory, 16 KB of SRAM, and 512 B of EEPROM. The device operates within a voltage range of 1.8 V to 5.5 V and supports temperatures from -40°C to +125°C. It is housed in a QFN package with 32 pins, providing up to 27 general-purpose I/Os. Key peripherals include a 12-bit ADC, DAC, three analog comparators, PTC, and UPDI.

Feature Summary

Supports Program and Debug Interface Disable (PDID) for secure firmware protection
Integrates Peripheral Touch Controller (PTC) with Driven Shield+ technology
Features an Event System for CPU-independent inter-peripheral signaling
Includes Configurable Custom Logic (CCL) with programmable Look-up Tables

Applications

Secure embedded control systems requiring firmware authentication
Capacitive touch interface designs using sliders or buttons
Low-power applications utilizing multiple sleep modes
Industrial monitoring devices operating across extended temperature ranges

Procurement Notes

Verify that the ordering suffix 'QZB' corresponds to the specific QFN package variant listed in official Microchip documentation. Confirm the 'S' designation indicates the inclusion of the PDID security feature. Ensure the '-E' suffix matches the required extended temperature range specifications for your application environment before finalizing procurement.

Selection Notes

Select this component when 128 KB of program memory and 16 KB of data RAM are required within a compact 32-pin footprint. It is suitable for designs needing advanced analog features like the 12-bit ADC and integrated touch sensing capabilities. Consider this part if vertical migration within the AVR DA(S) family is planned without code modification.

Part Context

This device belongs to the AVR128DA28/32/48/64(S) series, which shares a common architecture and peripheral set scaled by pin count. It offers horizontal migration options to reduce pin counts while maintaining software compatibility. The family utilizes the latest low-power technologies and provides flexible event routing between peripherals.
