Summary datasheet for the tiny26, a 161 KB PDF whose s suffix denotes the abbreviated edition, matching the Atmel AVR ATtiny26 microcontroller. Expect a feature overview, pin configuration drawings, a register summary and package ordering information rather than complete chapters. On the bench it offers a fast way to confirm power, ground, reset and ADC pin positions. When electrical ratings, clock fuse settings or the programming procedure matter, switch to the full ATtiny26 datasheet, which is also in this collection.
