Product details

It integrates 512 bytes of EEPROM, a 22-channel 12-bit ADC, and a single 10-bit DAC, making it a fit for sensor-heavy control applications in industrial automation, building management, and instrumentation where analog signal acquisition and PWM-driven actuation share the same die.

This reduces supply-chain risk for designs entering production now or requiring multi-year availability.

Analog integration and peripheral set

With 22 analog inputs on the 12-bit ADC and a single 10-bit DAC, this part can handle multi-channel sensor acquisition and analog output generation without external converters.

Frequently asked questions

What are the programming options for AVR64DB64T-I/PT?

This MCU uses standard AVR programming interfaces — UPDI (Unified Program and Debug Interface) for in-system programming and debugging. It is supported by Microchip's MPLAB X IDE and tools like the PICkit 4 or MPLAB Snap.

Is AVR64DB64T-I/PT compatible with Arduino?

While not an official Arduino board, the AVR64DB64T-I/PT uses the same AVR core architecture as many Arduino-compatible microcontrollers. With the appropriate core support in the Arduino IDE (via Microchip's megaAVR 0-series or AVR DB core), it can be programmed in the Arduino environment, though some peripheral libraries may need adaptation.
