Procurement Notes

Verify the specific ordering suffix to confirm package type and temperature range. The 'XF' designation indicates a TSSOP/SSOP package with extended temperature capabilities. Ensure compatibility with existing board layouts due to pin-to-pin requirements within the family. Confirm supply chain availability directly with Microchip Technology or authorized distributors.

Selection Notes

Select this model when 18 I/O pins and 16 KB of program memory are required. Consider the tinyAVR® 2 family benefits like vertical migration without code modification. Evaluate the need for the 12-bit ADC resolution and PGA for precision sensing tasks. Verify that the TSSOP/SSOP package fits the mechanical constraints of the target application.

Part Context

This component belongs to the tinyAVR® 2 family, which shares architectural similarities with the ATtiny1624 and ATtiny1627. It offers horizontal migration options to reduce pin counts while maintaining feature compatibility. The family emphasizes low power consumption and high performance for embedded control applications.
