Posted on January 23, 2006 at 07:09We now believe that what was percieved as an 'ADC fault' is caused by a component failure on another part of our circuit. And not a fault on the ST10F269. Thanks for your input. The points raised were a useful desi...
Posted on January 04, 2006 at 14:24Can anyone tell me what the difference is between a ST10F269Q3 and a ST10F269Z1Q3? I understand that the difference between Z1 and Z2 devices is the amount of FLASH (Z1 = 128k, Z2 = 256k). But not found suitable ex...
Posted on January 03, 2006 at 06:47To hopefully clarify… The device generating VAREF is powered by the same VDD supply as the F269. I believe that VAREF should never ‘exceed’ VDD, as the MAXIM device is not designed to generate an output volta...
Posted on December 22, 2005 at 11:29Hi Neila. Thanks. I have taken scope traces of the power-up sequence of my circuit. VAREF is generated by a MAX6041AEUR device, powered by the same ‘VDD’ of the F269. At ‘power on’ VAREF lags VDD for about...
Posted on December 14, 2005 at 07:31Thanks for the reply Najoua. I have checked that the P5DIDIS reg is set correctly. I should add, this failure is intermittent, AND it only occurs on 3 boards out of 100. As I have many boards operating correctly, ...
