AVR128DA32ST-E/QZB

Overview

The AVR128DA32ST-E/QZB is a 32-pin microcontroller from the AVR DA(S) family, featuring an AVR CPU with hardware multiplier running at up to 24 MHz. It includes 128 KB of Flash memory, 16 KB of SRAM, and 512 B of EEPROM. The device supports a supply voltage range of 1.8 V to 5.5 V and operates within an extended temperature range of -40°C to +125°C. It integrates advanced analog features including a 12-bit ADC, DAC, and Peripheral Touch Controller (PTC).

Feature Summary

Integrated Program and Debug Interface Disable (PDID) for secure firmware protection.
Supports capacitive touch sensing via Peripheral Touch Controller (PTC) with Driven Shield+ technology.
Features intelligent analog peripherals including a 12-bit differential ADC and Zero-Cross Detectors (ZCD).

Applications

Secure embedded control systems requiring firmware authentication.
Industrial applications utilizing capacitive touch interfaces.
Power control circuits using integrated zero-cross detection.

Procurement Notes

Verify that the ordering suffix QZB corresponds to the specific package variant defined in the official Microchip datasheet DS40002183E. Confirm the E suffix indicates the extended temperature rating (-40°C to +125°C). Ensure the T suffix denotes tape and reel packaging if applicable to your assembly process. Cross-reference the part number against the manufacturer's current product status to confirm availability.

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 extended temperature operation and enhanced security features like PDID. Consider the 32-pin form factor for balanced I/O count and package size constraints compared to 28 or 48-pin variants.

Part Context

This device belongs to the AVR128DA28/32/48/64(S) series, which shares a common architecture and peripheral set across pin counts. The AVR DA(S) family utilizes the latest low-power technologies and offers horizontal migration capabilities by reducing pin counts while maintaining software compatibility.
