Procurement Notes

Verify the specific ordering suffix 'N' against official manufacturer documentation to confirm the package type and lead finish specifications. Ensure that the selected variant matches the required industrial temperature range and speed grade for your application environment. Cross-reference the datasheet revision to confirm compatibility with existing design files and errata notices before finalizing procurement orders.

Selection Notes

Select this component when a balance of processing speed and low power consumption is required for space-constrained designs. The 10 MHz speed grade provides sufficient throughput for simple control loops while maintaining efficiency. Consider the 1.8 V minimum operating voltage if designing for battery-operated systems where energy conservation is critical. Verify that the 6 available I/O lines meet the interface requirements for sensors and actuators.

Part Context

This device belongs to the ATtiny family of 8-bit microcontrollers based on the AVR core. It shares architectural similarities with the ATtiny45 and ATtiny85, differing primarily in memory capacity. The 'V' designation indicates extended voltage range capability down to 1.8 V. The series is designed for cost-sensitive applications requiring reliable performance in compact form factors.
