4/15/2023 0 Comments Serial port programmer for at89s52I read the manual and it doesn't answer my questions. I see they also have serial programming lines. I recently ordered a large number of AT89LP4052's online due to their higher speed properties. Decoupling capacitor is 100uF electrolytic. Crystal is 20Mhz and caps connected to it are 33pF. The nice part is that the thing works, however each time I want to initiate a new session I have to disconnect the circuit from the power and PC and short the power lines together then reconnect everything. I made an AT89S52 programmer as shown below to be used with the PC parallel port.
