• Includes accurate analog subsystems such as a 12-bit differential ADC with PGA and 10-bit DAC
• Supports single pin Unified Program and Debug Interface (UPDI) for programming and debugging

Applications

• Real-time control systems
• Sensor nodes
• Secondary safety monitoring applications

Procurement Notes

Verify the specific ordering suffix against official Microchip documentation to confirm package type and temperature rating. Ensure compatibility with existing design constraints before procurement. Confirm that the component meets all required environmental specifications for the intended application environment.

Selection Notes

Select this model for designs requiring vertical migration within the AVR EA family without code modification. Consider the 28-pin SPDIP package for through-hole mounting requirements. Evaluate peripheral availability against project needs, noting that pin count variations affect available features across the family.

Part Context

This component belongs to the AVR EA family, which utilizes the latest Microchip technologies for efficient real-time control.
