Thanks for that wp100. But my question was really do chip programmers talk to similar chips the same way?
That is, will my programmer be able to communicate successfully with the 510 chip if it thinks it is communicating with a 509 chip (as long as the data, clock, Vpp Vss and Vdd are connected correctly)?
Or, does the chip selection on the programmer software do nothing more than arrange the connection of the data, clock, Vpp Vss and Vdd lines to the right pins?
Thanks.
