Browsing the Rapid website here
they seem to have several 28 pin DIP versions of the 168 listed:
ATMEGA168V-10PU 8BIT MICRO 16K
ATMEGA168-20PU 8-BIT MICRO 16K
ATMEGA168P-20PU 8 BIT MICRO 1K
The first 2 are nearly half the price of the last one… Does anyone know what the V/P & PU signify. Also the last one says 1K…?
The datasheet for the last one seems to actually point to the 164 so that’s not much help.
