AVR128DA32S-I/QZB

Overview

The AVR128DA32S-I/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 an industrial temperature range of -40°C to +85°C. It utilizes a 32-pin QFN package and incorporates the Program and Debug Interface Disable (PDID) security feature.

Feature Summary

Integrated Program and Debug Interface Disable (PDID) for secure firmware protection against unauthorized access
Peripheral Touch Controller (PTC) supporting capacitive touch buttons, sliders, wheels, and 2D surfaces
Event System enabling CPU-independent inter-peripheral signaling for predictable operation
Configurable Custom Logic (CCL) providing programmable Look-up Tables for custom digital logic

Applications

Secure embedded control systems requiring firmware authentication
Capacitive touch interface designs using self-capacitance or mutual capacitance sensors
Industrial automation controllers operating in standard industrial temperature environments
Low-power applications utilizing multiple sleep modes and internal oscillators

Procurement Notes

Verify that the specific ordering suffix matches the required package style and temperature grade. Confirm the presence of the PDID feature if security locking is necessary for the application. Ensure compatibility with existing design tools and programming interfaces before finalizing procurement decisions.

Selection Notes

Select this component when 128 KB of program memory and 16 KB of RAM are required alongside advanced analog peripherals. The inclusion of PDID distinguishes it from standard variants, making it suitable for applications needing enhanced security. Consider pin count and peripheral availability relative to other devices in the AVR DA(S) family.

Part Context

This part belongs to the AVR128DA28/32/48/64(S) series, which offers vertical migration without code modification. The 'S' designation indicates the inclusion of the PDID security feature. It shares architectural similarities with other AVR DA devices but provides specific memory and I/O configurations tailored for 32-pin implementations.
