Microchip ATTINY85-20SF 8-bit AVR Microcontroller 8KB Flash 20MHz SOIC-8 SMD

The Microchip ATTINY85-20SF is a high-efficiency 8-bit AVR RISC microcontroller engineered for space-constrained ultra-low-power applications. Packing 8KB of programmable flash memory into a compact SOIC-8 surface-mount package, it executes powerful instructions in a single clock cycle, striking the perfect balance between processing speed and minimal power consumption.

The “SF” suffix denotes an extended temperature profile (−40°C to +125°C), making it highly reliable for rugged automotive and industrial commercial hardware — a significant advantage over the standard breadboard-friendly DIP-8 ATTINY85-20PU variant.
