OK I know that somewhere in the 600+ page datasheet this is explained but it would be great if someone just knew the answer. I'm designing a little board to convert a small co-axial helicopter into an indoor drone. It uses to Sharp IR distance sensors and an gyro to fly autonomously around the room.
I have the board designed and am picking part numbers. At DigiKey there are several Atmel part numbers to choose from. (I'm talking Atmel part numbers not DigiKey part numbers). They all start with ATTINY45-20 but there are several suffixes to choose from. They are SUR, SU, SHR, and SH. I know from experience that the suffix for the micro in the Arduino determined if you could install a bootloader or not. Any advice?
Thanks
