#188958 - How dangerous power ups can be...
Responding to: ???'s previous message
...can be seen from this link:

http://www.ti.com/lit/ds/sbas203j/sbas203j.pdf

Please read page 27.

This underlines the importance of a controlled power up slope rate with modern flash memory micros.

   another solution            01/01/70 00:00      
   The probabilities are low...            01/01/70 00:00      
      think about what happens when you add a finger            01/01/70 00:00      
         The point is ...            01/01/70 00:00      
            Yes ... the underlying issue is the flash ...             01/01/70 00:00      
               Out of my office, but...            01/01/70 00:00      
                  Don't think in Vcc, ESD or hum...            01/01/70 00:00      
   Apparently several C8051F2xx parts have the same pinout            01/01/70 00:00      
   Characteristic for in system programmable flash micros...            01/01/70 00:00      
      All too true ... sadly ...             01/01/70 00:00      
         Power-on slope rate...            01/01/70 00:00      
            Sorry, my post should be here, no up there...            01/01/70 00:00      
            Have you any basis for that rate?            01/01/70 00:00      
               Vdd ramp time            01/01/70 00:00      
               Some datasheets show numbers...            01/01/70 00:00      
                  Those aren't the "usual" 805x-core MCU's            01/01/70 00:00      
                     There aren't many "usual" 8051-cores anymore...            01/01/70 00:00      
                        How dangerous power ups can be...            01/01/70 00:00      
                           I believe it            01/01/70 00:00      
                              (dV/dt) examples            01/01/70 00:00      
                                 They don't know it either...            01/01/70 00:00      
                                    dV/dT etc             01/01/70 00:00      
                                       reset request...            01/01/70 00:00      
                                          That's what disturbs me greatly            01/01/70 00:00      
                                             It IS disturbing!            01/01/70 00:00      
                                                Where this began ... at least for me ...             01/01/70 00:00      
                                                   So, you took the hard road...            01/01/70 00:00      
                                                      We've all had that experience             01/01/70 00:00      
   probable cause            01/01/70 00:00      
      Brent, this is very nice            01/01/70 00:00
