AVR64DA48S-I/PT

Overview

The AVR64DA48S-I/PT is an 8-bit microcontroller from Microchip Technology, based on the AVR architecture. It features 64 kB of Flash program memory and 8 kB of SRAM data memory. The device operates at a maximum clock frequency of 24 MHz with a supply voltage range of 1.8 V to 5.5 V. It includes a 12-bit ADC, three comparators, a DAC, and multiple communication interfaces including UART, SPI, and TWI. The component is housed in a 48-pin TQFP package.

Feature Summary

• Supports multi-voltage operation across the entire power supply range
• Integrates programmable threshold comparator (PTC) and zero-crossing detection (ZCD)
• Includes PDID for unique device identification
• Features hardware acceleration with an integrated multiplier

Applications

• Industrial control systems
• Home appliance controllers
• Automotive electronics
• Internet of Things (IoT) devices

Procurement Notes

Verify the specific suffix 'S' indicates tray packaging when sourcing. Confirm the operating temperature grade 'I' corresponds to -40°C to +85°C. Ensure compatibility with the AVR DA series pinout and software libraries. Check RoHS compliance status through official manufacturer documentation before integration.

Selection Notes

Select this model for applications requiring high I/O count with 48 pins. Choose over non-S variants if tray handling is preferred for assembly. Consider the 24 MHz speed and 12-bit ADC resolution for precision analog tasks. Verify that the 8-bit architecture aligns with existing development toolchains and codebases.

Part Context

This part belongs to the AVR64DA series, designed for real-time control in industrial and automotive environments. It shares architectural similarities with other AVR EA and DD series but offers specific interface counts and peripheral sets tailored for mid-range performance requirements within the 64 kB Flash category.

Replacement Considerations

AVR64DA48-I/PT is a compatible alternative differing primarily in packaging type.
