AVR128DA32T-E/PT

Overview

The AVR128DA32T-E/PT is an 8-bit microcontroller from the AVR DA family, featuring a 32-pin TQFP package. It includes 128 KB of Flash memory, 16 KB of SRAM, and 512 B of EEPROM. The device operates at a maximum clock frequency of 24 MHz with a supply voltage range of 1.8 V to 5.5 V. It supports an extended industrial temperature range of -40°C to +125°C.

Feature Summary

• Features a high-performance AVR CPU core with hardware multiplier and single-cycle I/O access.
• Includes advanced analog peripherals such as a 12-bit differential ADC, three analog comparators, and zero-cross detectors.
• Supports capacitive touch sensing via the Peripheral Touch Controller (PTC) with driven shield technology.
• Provides flexible inter-peripheral signaling through the Event System and configurable custom logic.

Applications

• Industrial control systems requiring robust peripheral integration
• Smart home appliances utilizing capacitive touch interfaces
• Power management applications using zero-cross detection
• Battery-powered devices benefiting from low-power sleep modes

Procurement Notes

Verify that the ordering suffix 'E' corresponds to the extended temperature range (-40°C to +125°C) and 'T' indicates tape and reel packaging. Confirm the pin count matches the 32-pin TQFP requirement for your PCB layout. Ensure compatibility with the UPDI programming interface for development and production flashing.

Selection Notes

Select this component when 128 KB of program memory and 16 KB of RAM are required within a compact 32-pin footprint. Choose the extended temperature grade for environments exceeding standard industrial limits. Consider the integrated PTC if touch functionality is needed without external controllers.

Part Context

This part belongs to the AVR128DA series, which offers vertical migration compatibility with other devices in the AVR DA family. It shares architectural similarities with the AVR32DA and AVR64DA variants but provides higher memory capacity. The device utilizes the Unified Program and Debug Interface (UPDI) for simplified connectivity.
