It’s quite a bit more real estate. An ATTiny45 is available as a TSSOP-8 and would need a 10k resistor (!RESET pullup) and a bypass cap (assuming the input was conditioned, which it would need to be for a discrete solution anyway). _______________________________________________ time-nuts mailing list -- [email protected] To unsubscribe, go to https://www.febo.com/cgi-bin/mailman/listinfo/time-nuts and follow the instructions there.
