AVR64DA64T-E/MR

Overview

The AVR64DA64T-E/MR is an 8-bit microcontroller from the AVR DA(S) family, featuring a 24 MHz AVR CPU with hardware multiplier. It includes 64 KB of Flash, 8 KB of SRAM, and 512 B of EEPROM. The device offers up to 55 programmable I/O pins in a VQFN-64 package. Key peripherals include six USARTs, two SPIs, two TWIs, one 12-bit ADC with 22 channels, three analog comparators, one DAC, three zero-cross detectors, and a Peripheral Touch Controller. Operating voltage ranges from 1.8 V to 5.5 V, with an extended temperature range of -40°C to +125°C.

Feature Summary

• Supports vertical migration within the AVR DA(S) family without code modification due to full pin and feature compatibility.
• Includes Program and Debug Interface Disable (PDID) for secure firmware upgrades and authentication.
• Features an Event System for CPU-independent inter-peripheral signaling and Configurable Custom Logic (CCL).
• Provides multiple voltage references including 1.024V, 2.048V, 2.500V, and 4.096V.

Applications

• Secure firmware upgrade implementations requiring PDID protection.
• Applications utilizing capacitive touch interfaces via the Peripheral Touch Controller.
• Systems requiring multi-voltage operation between 1.8V and 5.5V.
• Industrial control environments needing extended temperature performance.

Procurement Notes

Verify that the specific ordering suffix 'E' corresponds to the extended temperature range (-40°C to +125°C) as defined in the datasheet designation table. Confirm the 'T' suffix indicates tape and reel packaging and the 'MR' suffix denotes the VQFN-64 package style. Ensure the component matches the exact part number AVR64DA64T-E/MR to guarantee correct peripheral counts and memory specifications.

Selection Notes

Select this variant when an extended operating temperature range up to +125°C is required compared to the industrial grade. The 'T' suffix designates tape and reel packaging suitable for automated assembly processes. The 'MR' suffix specifies the VQFN-64 package, providing the maximum I/O count of 55 pins available in the 64-pin device class.

Part Context

This component belongs to the AVR64DA28/32/48/64(S) series, which shares a common architecture and instruction set. Devices in this family are vertically compatible, allowing migration between different pin counts while retaining software compatibility. The 64-pin variant provides the highest peripheral density, including the maximum number of USARTs and ADC channels in the 64 KB Flash class.
