Memories Forum Discussions

I am looking at the 25 Series Nor Flash memories and was wondering whether a verilog/vhdl implementation of a memory controller which can connect to this device in QSPI mode exists.

When using CY15B102Q-SXET originally produced by your company, we found that the side of the pin of CY15B102Q-SXET(SOIC-8 package) does not tin, so we need to increase the soldering iron temperature and welding time to repair the solder joint of the pin. But this method will cause hidden trouble to the quality of the chip.
Subsequently, our company transferred ten CY15B102Q-SXET from the warehouse. Before any treatment, all the chip pins showed a dull and dull state; After operation according to method 2003.1 weldability of "GJB548B-2005 Test Method for Microelectronic Devices", all chip pins show bright coating, continuous tin surface, full coating and good tin from the front view; When all the chips were raised to observe the side of the pins, it was found that there were pitting points, no wetting of the coating and discontinuous tinning on the side of the pins.
We believe that this situation is not the cause of preservation, but the quality of the device reference script. If it is a preservation problem, it should be that the entire pin is not oxidized on the tin; However, after the test, the pin face, the front heel, the back heel to follow the tin are particularly good, only the two sides of the pin on the tin effect is particularly poor.
Could you tell us how we should handle this situation? Looking forward to your reply very much.
