Feature Summary

• AVR CPU with single-cycle I/O access and two-cycle hardware multiplier
• In-system self-programmable Flash memory with automated CRC scan
• Multi-Voltage I/O (MVIO) on I/O port C with selectable input thresholds
• Single-pin Unified Program and Debug Interface (UPDI)

Applications

• Industrial control systems requiring robust I/O flexibility
• Low-power embedded applications utilizing multiple sleep modes
• Systems needing precise timing via hardware timers and event system
• Analog signal processing using differential ADC and DAC

Procurement Notes

Verify the ordering suffix 'T' indicates tape and reel packaging and 'SO' denotes the SOIC package style. Confirm the 'I' suffix specifies the industrial temperature range of -40°C to +85°C. Ensure compatibility with the AVR DD Family pinout for vertical migration projects. Cross-reference the datasheet DS40002315C for complete electrical specifications and mechanical dimensions before finalizing procurement orders.

Selection Notes

Select this component when 16 KB of Flash and 2 KB of SRAM are sufficient for application requirements. Consider the 20-pin SOIC package for space-constrained designs compared to larger variants. Evaluate the need for Multi-Voltage I/O capabilities if interfacing with different voltage domains. Verify that the 24 MHz maximum frequency meets the processing speed demands of the target application.

Part Context
