Post by thread:[PIC:] PIC in hostile enviroment

Hi All, with the help of some PIClisters, i'm developing a distributorless ignition module for a jeep, all the pieces match together, and the problem seems to face the software side. Since i'm not and EE, but a software guy with no experience in circuits in real life, i'm concerned about how robust is a solution based in pic + consumer electronics, i can trust in pic products for a real application? (no flames, i have developed products with months of operation, but no one in an automotive or critical enviroment), are products more releables than others? i can take some special precautions with enclosure or pcb (home made, no smt)?, how about the other electronics components?, and finally, where i can read some about noise filtering in power supply, inputs and outputs that works well? thaks in advance RVP. ____________________________________________

You need to read Intel's appnote #AP-125, "Designing Microcontroller Systems for Electrically Noisy Environments". Written over a decade ago, and still the best I've seen at describing the problem and suggesting solutions. Go to http://www.intel.com and search for "ap-125". -Andy === Andrew Warren - .....aiwKILLspam@spam@cypress.com === === Principal Design Engineer === Cypress Semiconductor Corporation ____________________________________________
