Introduce a comparison between a WINBOND serial Flash W25Q40CLSNIG and GD25Q40CTIG.

 The parameter comparison between Zhaoyi GD25Q40CTIG and Winbond W25Q40CLSNIG is shown in the following table:

Table 1 Comparison of parameters of GD25Q40CTIG and W25Q40CLSNIG 

From the above table, we can see that the parameters of GD25Q40CTIG and W25Q40CLSNIG are basically the same in terms of memory, operating voltage, operating temperature, and packaging. In theory, the two can replace each other. GD25Q40CTIG and W25Q40CLSNIG package comparison:
