Hi there im having probs getting the chip to ID or read its a MX25L6405 i dont have the adapter for it but i soldered each of the legs to DIL socket as i have shown in the pics below.
I have previously done this before with the smaller MX25L1605 and not had any probs but i just cant get anywhere with the MX25L6405,
Has anyone read/wrote one of these chips before or have any info? ive tried reading with the FFFF ID but it reads nothing.
Thanks |

Your chip is not SOIC 8 pin chip.
It is SOP 16 (300mil)chip.
See:
So, your chip pins must be mapped to 8 pins pinout.
Currently we do not have direct adapter for this SOP 16 chip on GQ-4X. But you can do it youself.
Map following pins on your SOP16 chip to 8 pin pinout based on the same pin name between them:
1,2,7,8,9,10,15,16
example: pin 1 on your SOP 16 chip map to pin 7 on SOIC 8 pin chip.
Finaly, only 8 pins go into the programmer ZIF socket.
All other pins are not used on this SOP16 chip. |

Ive ordered an adapter so ill wait till that arrives and then test it on a different modems spi chip |

MX25L1605 and MX25L6405 should use exact same commands to access the EEPROM. So, if your connection are all good and correct, then change another chip and try again. All 8 pins should be connected. Use blank check to confrim read all FF. |
