Overview
The AVR128DA48T-E/PT is an 8-bit microcontroller from the AVR DA family, featuring a 128 KB Flash program memory, 16 KB SRAM, and 512 B EEPROM. It operates at a maximum clock frequency of 24 MHz with a supply voltage range of 1.8 V to 5.5 V. The device includes a 12-bit differential ADC with 18 channels, a 10-bit DAC, three analog comparators, and three zero-cross detectors. It provides 41 general-purpose I/O pins in a TQFP-48 package and supports extended temperature operation from -40°C to +125°C.
Feature Summary
- AVR CPU with hardware multiplier running up to 24 MHz
- Integrated Peripheral Touch Controller (PTC) for capacitive touch applications
- Event System enabling CPU-independent inter-peripheral signaling
- Configurable Custom Logic (CCL) with programmable Look-up Tables
Applications
- IoT device prototyping
- Industrial control systems
- Smart home appliances
- Battery-powered sensor nodes
Procurement Notes
Verify that the ordering suffix 'E' corresponds to the extended temperature range (-40°C to +125°C) and 'PT' indicates the TQFP package. Confirm the 'T' suffix denotes tape and reel packaging if required for automated assembly. Ensure compatibility with UPDI programming interfaces.
Selection Notes
Select this component when high peripheral density and low-power operation are required within the AVR architecture. The DA family offers vertical migration compatibility with other AVR devices. Consider the 12-bit ADC resolution and PTC capabilities for precision analog and touch sensing tasks.
Part Context
This part belongs to the AVR128DA28/32/48/64 series, designed for flexible and low-power applications. It shares architectural similarities with previous AVR generations but introduces advanced digital peripherals and intelligent analog features. The device supports single-pin unified programming and debugging via UPDI.

FAQ
What is the function of the Event System in the AVR128DA48?
The Event System allows peripherals to communicate directly without CPU intervention, enabling predictable and efficient signal transmission between components.
Does the AVR128DA48 support simultaneous master and slave operation on TWI?
Yes, the TWI/I2C interface can operate simultaneously as a master and a slave on different pins, supporting dual address match functionality.
How does the Peripheral Touch Controller (PTC) enhance touch sensing?
The PTC utilizes Driven Shield+ and Boost Mode technologies to improve sensitivity and reliability for capacitive touch buttons, sliders, wheels, and 2D surfaces.
