AVR128DA32ST-E/PT

Overview

The AVR128DA32ST-E/PT is an 8-bit microcontroller from the AVR DA(S) family, featuring a 32-pin TQFP package with the PDID security feature. 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 a supply voltage range of 1.8 V to 5.5 V and functions within an extended temperature range of -40°C to +125°C.

Feature Summary

Includes Program and Debug Interface Disable (PDID) for secure firmware upgrades and authentication
Integrates Peripheral Touch Controller (PTC) with Driven Shield+ technology for capacitive touch applications
Features an Event System for CPU-independent inter-peripheral signaling and Configurable Custom Logic (CCL)
Provides intelligent analog peripherals including a 12-bit ADC, three Analog Comparators, and Zero-Cross Detectors

Applications

Secure firmware upgrade implementations requiring code protection
Capacitive touch interfaces such as buttons, sliders, and wheels
Power control systems utilizing optimized Timer/Counter type D
Industrial automation devices operating in extended temperature environments

Procurement Notes

Verify that the ordering suffix 'S' confirms the inclusion of the PDID security feature, as this distinguishes it from standard variants. Ensure the 'E' suffix matches the required extended temperature range specifications for your application environment. Confirm the 'T' suffix indicates tape and reel packaging if automated assembly is planned.

Selection Notes

Select this component when vertical migration within the AVR DA(S) family is required without code modification. Choose this part over non-PDID versions if hardware-based security against remote or PCB-level attacks is mandatory. Consider the 32-pin form factor for balanced I/O availability and package size constraints.

Part Context

This device belongs to the AVR128DA28/32/48/64(S) series, which shares a flexible low-power architecture. It offers horizontal migration capabilities to reduce pin counts while maintaining software compatibility. The 'S' designation specifically denotes the presence of the PDID feature for enhanced security compared to standard AVR DA parts.
