Testing SPI Flash Programmer v2

I found one flash memory PM25LV512 of the graphic card from pc , and put it to programmer to see how it looks in action. The PM25LV512 is a Serial Flash Memory With 25 MHZ Spi Bus Interface and these devices are designed to use a single low voltage, range from 2.7V  to 3.6V so this mean before to put tha flash memory in programmer you must control the jumpers position to be on 3.3V. Here some pictures to see how look.

 

Make sure to control the jumpers position .

Put the memory to the DIL socket
Turn ON the programmer

Open your software SPI Flash Programmer and choice the flash memory in this case it it’s PMC PM25LV.

Click on the read device
And this is all procedure about reading Flash memory.
