#116884 - AVR Vs PIC ! Responding to: ???'s previous message |
2 month's ago i had an offer from one of my customer that they insist to using PIC
for their project, Unfortunately that was force enough that i couldn't switch to PIC those days They said PIC is industrial and less noisy, But I could change their opinion to use 8051 I hear it day after day. This has been somehow discussed here before. IMHO, If you design your PCB correctly with suitable ground planes and use protection diodes where needed and use buffers for line drivers and etc, etc there is no such a thing as having random resets or alike. I heard such comments from The people who e.g. try to use a port of AT89S51's to drive 4 LEDs and send 2 bits on a 60 CM cable and directly connect the remaining pins as inputs (where they may have high frequency noises). If I recall correctly this subject has been came around sometimes and members said the same answer. PICs have Clamp diodes on their input that protects their inputs from a negative or a big positive signal. Personally, I didn't have any experience using either 8051s or AVRs in an industrial environment. In Automotive applications both 8051 and AVR did performed well for my applications. Farshid |
