AVR64DA64-I/PT

Overview

The AVR64DA64-I/PT is an 8-bit microcontroller from the AVR DA family, featuring a 24 MHz AVR CPU with hardware multiplier. It includes 64 KB of Flash memory, 8 KB of SRAM, and 512 B of EEPROM. The device provides up to 55 programmable I/O pins in a TQFP-64 package. Key peripherals include six USARTs, two SPI interfaces, two TWI/I2C interfaces, a 12-bit differential ADC with 22 channels, three analog comparators, three zero-cross detectors, and a Peripheral Touch Controller.

Feature Summary

• Supports vertical migration within the AVR DA(S) family without code modification due to full pin and feature compatibility.
• Integrates an Event System for CPU-independent inter-peripheral signaling and Configurable Custom Logic (CCL).
• Includes advanced analog features such as a 12-bit differential ADC with programmable gain amplifier and window compare functions.
• Offers security features including Program and Debug Interface Disable (PDID) for protected firmware upgrades.

Applications

• Industrial control systems requiring real-time processing and multi-voltage operation.
• Smart home appliances utilizing capacitive touch interfaces via the Peripheral Touch Controller.
• Internet of Things (IoT) devices needing secure firmware updates and low-power sleep modes.
• Automotive applications compatible with industrial temperature ranges (-40°C to +85°C).

Procurement Notes

Verify the specific ordering suffix to confirm the package style and temperature range. The 'I' suffix indicates an industrial temperature range of -40°C to +85°C, while 'E' denotes extended range. Ensure the 'PT' suffix corresponds to the TQFP package type required for your PCB layout. Cross-reference the datasheet revision DS40002233C for any errata or programming guidelines relevant to production implementation.

Selection Notes

Select this component when high pin count and extensive peripheral integration are required within the 8-bit AVR architecture. It is suitable for designs needing multiple serial communication interfaces and precise analog signal acquisition. Consider the vertical migration path if future scalability within the DA family is anticipated. Evaluate the power consumption requirements against the available sleep modes and clock options.

Part Context

This part belongs to the AVR64DA28/32/48/64(S) series, which shares a common core and peripheral set scaled by pin count. The 64-pin variant offers the maximum I/O and peripheral availability for the 64 KB Flash class. It sits alongside the AVR128DA and AVR32DA families, providing a flexible platform for various memory and performance needs.
