My VAS5054a has a very genuine looking AM29F160DB flash chip, so I am leaving that alone. (20-09-2017, 19:03 PM)apoelistas Wrote: How can we check the voltage going to the memory chip?? I need to test if voltage before memory is 3.3V or 5V because I don't want to change memory type to 5V but then I will discover that the voltage supplied is 3.3V because they have also changed another parameter. Well, original VAS5054a tool has 5 volt memory, so it's very safe to assume they're being fed 5V, as it wouldn't work well on 3.3V. Pin 11 of sram is +5V (VCC) Pin 12 of sram is ground (VSS) |
