Overview
The AVR64DA64-E/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 ADC with 22 channels, three analog comparators, three zero-cross detectors, and a Peripheral Touch Controller (PTC). 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.
- Integrates intelligent analog features including a 12-bit differential ADC, analog comparators, and a Peripheral Touch Controller for capacitive touch applications.
- Provides advanced digital peripherals such as Configurable Custom Logic (CCL), Event System, and multiple high-speed communication interfaces.
- Includes security features like Program and Debug Interface Disable (PDID) for secure firmware upgrades and authentication.
Applications
- Real-time control systems requiring low-power performance
- Sensor nodes utilizing capacitive touch interfaces
- Secondary security monitoring devices
- Closed-loop control system designs
Procurement Notes
Verify the specific ordering suffix '-E' confirms the extended temperature range (-40°C to +125°C) and '-PT' indicates the TQFP package style. Ensure the datasheet DS40002233C is referenced for complete electrical characteristics and pinout details. Confirm that the required peripheral count matches the 64-pin variant specifications.
Selection Notes
Select this component when 64 KB of Flash and 55 I/O pins are required. The extended temperature grade is suitable for harsh environments. Consider the availability of six USARTs and multiple timers if complex communication or timing tasks are needed. Verify power supply constraints align with the 1.8 V to 5.5 V operating range.
Part Context
This part belongs to the AVR DA(S) family, which combines the AVR CPU with Kernel Independent Peripherals (CIP) and smart analog features. The family offers horizontal and vertical migration paths across different pin counts and memory sizes while maintaining software compatibility. The AVR64DA64 represents the highest pin count and peripheral density in the 64 KB Flash segment.
Replacement Considerations
AVR64DA64-I/PT is available with an industrial temperature range instead of extended. Other family members like AVR64DA48 or AVR64DA32 offer fewer pins and peripherals but maintain software compatibility for horizontal migration.
