#124672 - is aduc84x fragile? Responding to: ???'s previous message |
i investigated the reset problem by observing the display of the device. also sometimes the device seems to jump to a wrong address during the burst test. i know it is not enoug to place by pass caps to power in pins of the device. but nearly the same circuitary worked with st micro without any problem.
aduc 834 is more slower than the aduc 848. so i think it can be more immune to the disturbances. i wonder weather the designers are satisfied by the noise immunity of the aduc84x. has anybody designed commerical devices with aduc84x in this site? |
