                      |  Hello, is it possible to read/write to 25VQ40ATIG chip on GQ-4x4 True USB Willem programmer? I don't see this chip on the devices list, but maybe some other chips are compatible? I cannot find the datasheet for 25VQ40ATIG, though, so can not be sure if any of different 25Q40 chips are compatible? Any help would be very much appreciated. Thank you. |

  The question is, would the GQ-4x4 be able to program it? Which device should I select?
 
 
  
  W25Q40EW
 
 
  
  The W25Q40EW is a 1.8V part, I've measured in-circuit Vcc of my part as 3.3V. I tried the W25Q40CL, the chip was detected as Exar, but then read failed...
  So I've just submitted, via GQ Application, a request to add a new chip. Hopefully it won't be too long?... |
