Overview
The AVR64DA48T-I/PT is an 8-bit microcontroller from the Microchip AVR DA series, featuring a 64 kB Flash program memory and 8 kB SRAM. It operates at a maximum clock frequency of 24 MHz within a TQFP-48 package. The device supports a supply voltage range of 1.8 V to 5.5 V and functions between -40°C and +85°C. Key peripherals include a 12-bit ADC with 10 channels, three analog comparators, a programmable temperature sensor (PTC), zero-crossing detectors, a DAC, six UARTs, two SPI interfaces, and TWI.
Feature Summary
- Integrates multiple communication interfaces including six UARTs, two SPI modules, and TWI for versatile connectivity.
- Features high-resolution signal processing capabilities with a 12-bit ADC and dedicated zero-crossing detectors.
- Includes specialized sensing hardware such as a programmable temperature sensor and three analog comparators.
Applications
- Industrial control systems requiring multiple serial communication links
- Smart metering applications utilizing zero-crossing detection
- Temperature monitoring devices leveraging integrated PTC sensors
Procurement Notes
Verify the exact part number suffix against official documentation, as standard listings typically use 'AVR64DA48T-I/PT'. Confirm that the 'ST' designation does not imply a specific tape-and-reel variant or packaging difference distinct from the standard reel option. Ensure the operating temperature grade matches industrial requirements.
Selection Notes
Select this component when high pin count and extensive peripheral integration are required in a compact TQFP-48 form factor. The availability of six UARTs makes it suitable for complex multi-device networks. Consider the 1.8V to 5.5V operating range for flexible power supply designs.
Part Context
This device belongs to the AVR DA family, designed for cost-sensitive applications requiring robust peripheral sets. It shares architectural similarities with other AVR EA and DB series members but offers specific interface counts like six UARTs and dedicated zero-crossing detectors tailored for AC mains monitoring and industrial automation.
Replacement Considerations
Cross-reference with AVR64DA48-I/PT for tray-packaged equivalents or AVR64EA48T-I/PT for similar performance with different peripheral configurations. Verify pin compatibility and software register mapping before substitution.
