Procurement Notes

Verify that the specific part number suffix matches the required package type and speed grade. Confirm that the voltage rating aligns with the system's power supply specifications. Ensure compatibility with existing programming interfaces such as SPI or debugWIRE. Check for any specific environmental compliance requirements relevant to the deployment region.

Selection Notes

Select this component when a balance of processing speed and low power consumption is required. The 1.8 V to 5.5 V operating range provides flexibility for various power supply designs. Consider the available I/O lines and peripheral count against application requirements before choosing alternative members of the ATtiny family.

Part Context

This device belongs to the ATtiny24/44/84 family of 8-bit AVR microcontrollers. It shares the same core architecture and peripheral set as the ATtiny24 and ATtiny84, differing primarily in memory capacity. The 'V' suffix indicates support for lower supply voltages down to 1.8 V, while the '10' denotes the maximum operating frequency.
