Overview
The AVR128DA64T-I/MR is an 8-bit microcontroller from the AVR DA family, featuring a 24 MHz AVR CPU with hardware multiplier. It includes 128 KB Flash, 16 KB SRAM, and 512 B EEPROM. The device operates between 1.8 V and 5.5 V within an industrial temperature range of -40°C to +85°C. It provides 55 I/O pins in a 64-pin VQFN package and supports interfaces including USART, SPI, TWI/I2C, UPDI, and PTC.
Feature Summary
- Integrates intelligent analog features such as a 12-bit ADC, DAC, and zero-cross detectors for signal conditioning.
- Supports capacitive touch applications via the Peripheral Touch Controller (PTC) with driven shield technology.
- Enables low-power operation through multiple sleep modes and auto-tuning internal oscillators.
- Facilitates real-time control using the Event System for peripheral-to-peripheral signaling without CPU intervention.
Applications
- Wired and wireless communication stacks
- Capacitive touch user interfaces
- Power control systems
- Smart home appliances
Procurement Notes
Verify the 'T' suffix indicates tape and reel packaging and the 'MR' suffix denotes the VQFN-64 package. Confirm the 'I' suffix matches the required industrial temperature range of -40°C to +85°C. Ensure the ordering code aligns with the specific datasheet revision DS40002183B.
Selection Notes
Select this part when vertical migration within the AVR DA family is required without code modification. Choose this model if 128 KB program memory and 55 general-purpose I/O pins are necessary. Consider this device for designs requiring high-performance analog peripherals alongside standard digital interfaces.
Part Context
This component belongs to the AVR128DA28/32/48/64 series, which shares pin and feature compatibility across different pin counts. The 'AVR128' designation indicates 128 KB of Flash memory, while 'DA' identifies the specific family architecture utilizing Intelligent Analog and CIP technologies.

FAQ
What does the 'MR' suffix indicate in the part number?
The 'MR' suffix specifies that the device is packaged in a 64-pin VQFN (Very Thin Quad Flat No-leads) format.
Can the device operate at frequencies higher than 24 MHz?
The CPU runs at up to 24 MHz, but an internal PLL can generate up to 48 MHz specifically for the Timer/Counter type D peripheral.
Is the device compatible with automotive standards?
No, the AVR128DA64T-I/MR is rated for industrial temperatures (-40°C to +85°C) and does not carry AEC-Q100 certification.
