The agent of Boya, in this article we will discuss the feasibility of replacing Boya SPI Nor Flash BY25Q64ASSIG and Winbond W25Q64JVSSIQ. The parameter comparison between BY25Q64ASSIG and W25Q64JVSSIQ is shown in the following table:

Table 1 Comparison of BY25Q64ASSIG and W25Q64JVSSIQ parameters

As can be seen from the above table,

1. BY25Q64ASSIG and W25Q64JVSSIQ memory, working voltage, working temperature, packaging and other parameters are the same;

2. The frequency of W25Q64JVSSIQ is slightly higher than that of BY25Q64ASSIG;

3. The power consumption of BY25Q64ASSIG and W25Q64JVSSIQ is basically the same in low power consumption mode. Comparison of BY25Q64ASSIG and W25Q64JVSSIQ pin distribution:

Table 2 W25Q64JVSSIQ pin definitions 

As can be seen above, BY25Q64ASSIG and W25Q64JVSSIQ have the same package, the same pin distribution, and basically the same pin definition. In summary, Boya Technology's industrial-grade SPI Nor Flash BY25Q64ASSIG can be replaced with Winbond's W25Q64JVSSIQ.
