Procurement Notes
Verify the ordering code matches the specific speed grade and package requirements for your application. Confirm that the industrial temperature range (-40°C to +85°C) aligns with your operational environment. Ensure compatibility with your programming interface, as the device supports In-System Programming via SPI.
Selection Notes
Select this component when a balance of processing speed and power efficiency is required in a compact 8-pin SOIC package. Consider the 20 MHz maximum clock speed for applications needing faster execution than lower-speed variants offer. Evaluate the available I/O lines and peripheral options against your system's connectivity needs.
Part Context
This part belongs to the ATtiny25/45/85 family of 8-bit microcontrollers based on the AVR enhanced RISC architecture. These devices are designed for cost-sensitive applications requiring moderate performance and low power consumption. The family shares common core features but varies in memory size and pin count.
