AVR128DA32-E/PT

Overview

The AVR128DA32-E/PT is an 8-bit microcontroller from the AVR DA 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 provides 27 general-purpose I/O pins in a TQFP-32 package. Key peripherals include a 12-bit ADC with 14 channels, three analog comparators, three zero-cross detectors, a 10-bit DAC, and a Peripheral Touch Controller.

Feature Summary

Integrates intelligent analog features including a 12-bit differential ADC, three analog comparators, and three zero-cross detectors for precise signal processing.
Supports capacitive touch applications via the Peripheral Touch Controller (PTC) with Driven Shield+ and Boost Mode technologies.
Enables flexible inter-peripheral communication through the Event System and Configurable Custom Logic (CCL).
Features a single-pin Unified Program and Debug Interface (UPDI) for simplified programming and debugging workflows.

Applications

Smart home devices requiring low-power operation and capacitive touch interfaces.
Industrial control systems utilizing multi-voltage I/O and robust analog signal conditioning.
Battery-powered appliances needing extended temperature range reliability and efficient power management.

Procurement Notes

Verify the specific ordering suffix against official Microchip documentation to confirm package type and temperature grade. Ensure compatibility with existing design constraints regarding pin count and peripheral availability. Cross-reference datasheet revisions to validate feature sets before finalizing procurement specifications.

Selection Notes

Select this component when vertical migration within the AVR DA family is required without code modification. Choose this model for designs needing 27 I/O pins with high-end analog capabilities like ZCDs and PTC. Consider the extended temperature rating (-40°C to +125°C) for harsh environment deployments where standard industrial grades are insufficient.

Part Context

This device belongs to the AVR128DA series, which shares architectural similarities with the AVR DB and AVR DA families. It offers horizontal migration options to lower pin counts or vertical scaling to higher density variants like the AVR128DA48/64. The architecture emphasizes low power consumption and advanced digital peripherals suitable for complex embedded tasks.
