• Includes a 12-bit differential Analog-to-Digital Converter (ADC) optimized for precision measurements.
• Integrates Configurable Custom Logic (CCL) with Look-up Tables for hardware logic implementation.
• Supports simultaneous host and client operation on the Two-Wire Interface (TWI).

Applications

• Industrial control systems requiring robust analog signal processing.
• Smart energy metering applications utilizing MVIO capabilities.
• Low-voltage embedded devices operating within the 1.8V to 5.5V range.

Procurement Notes

Verify the specific ordering suffix 'T' indicates tape and reel packaging when sourcing components. Confirm the 'I' suffix corresponds to the industrial temperature range of -40°C to +85°C. Ensure compatibility with the TQFP-32 footprint during PCB layout finalization. Cross-reference the datasheet DS40002315 for complete electrical specifications before integration.

Selection Notes

Select this component for designs requiring vertical migration within the AVR DD family without code modification. Consider the 24 MHz performance limit and 16 KB memory capacity against application requirements. Evaluate the 23-channel ADC availability if extensive analog input monitoring is necessary. Verify that the TQFP-32 package dimensions fit the mechanical constraints of the target enclosure.
