Post by thread:[EE] Interfacing PIC to automotive electric's?

18/5/2000 Can of worms can of worms! There is the simple way, then there is the correct way. Just of interest the relevant specifications are:- CISPIR 25 1995-11 ISO/TR 10605 1994(e) Japanese blue book ISO 11452 1995(e) MIL STD 461D ISO 7637 (Gives the impulse tests) SAE J1112-13 1995 SAE J1113-42 1994 OK! So for protection you can use a normal resistive divider and then pass this into a ESD device like a California micro P002 etc. Your main problems are susceptibility, we now are testing with values of up to (Get this one people if you think your world is noisy! 200V/meter at frequencies up to 0.5MHz and 40V/meter amplitude modulated by 80% up to 10MHz) Failure rates are dependant on the module requirements etc. Dennis > {Original Message removed}
