• Communication nodes using USART, SPI, and TWI interfaces

Procurement Notes

Verify that the ordering suffix 'T' corresponds to Tape & Reel packaging and 'I' indicates the Industrial temperature range (-40°C to +85°C). Confirm the 'PT' suffix matches the TQFP-48 package requirement. Ensure the component is sourced from authorized distributors to guarantee authenticity and compliance with the preliminary datasheet specifications.

Selection Notes

Select this model when 16 KB of Flash and 2 KB of SRAM are sufficient for the application. It is suitable for designs requiring 48-pin packages with extensive I/O capabilities. Consider vertical migration within the AVR EA family if future upgrades to higher memory sizes are anticipated without code modification.
