Hello, in an ironic twist, the Philips 89C51RD2 we use for the control panels on Philips CT scanners has been discontinued due to Philips selling it's semi-conductor operations last year. So I was wondering if anyone had a good substitute they had tried ???
Thanks, Don
Has anybody actually used a P89CV51 part. I just got the 1st sample today. It did not drop in and work. Flash magic went thru the motions but the part does not run my application. Instead it appears to send garbage out the serial port and it resets over and over. The only clue i have is that Flashmagic does not report or program the 6/12 clk bit correctly, not sure which. It always reports a 12 clk setting after programming even with the prog clocks box is checked. So i suspect flashmagic is not quite right.
one difference, probably the one that hit you is the 6/12 clock switching is not iodentical. The 'C' has a fuse, the 'V' has a SFR.
are you running 6 or 12?
I also believe the default is the opposite.
HOWEVER, to the best of my recollection (I left these for SILabs [needed the speed]} the bits needed for the 'V' are 'don't care' in the 'C'

we occasionally have these threads that are in the wrong category (251 for a 51 here) is there a way to make the main header change?
