Using CY7C65632-48AXCT instead of CY7C65634-48AXCT .

[NoAr_1540581]

Hello

They have already created a board with CY7C65634-48AXCT and is using it as a DS2 port product.
However, they are thinking of using the same board and replacing it with CY7C65632-48AXCT instead of CY7C65634-48AXCT .However, it will be used as a DS2 port product like the current CY7C65634-48AXCT.

So, thay are going to use CY7C65632-48AXCT as a 2-port product.In this CASE, If they check the terminal table on the data sheet, it seems that VCC_A of Pin # 19 becomes an NC terminal and the power supply is reduced by one.

(Q) If V CC_A of Pin # 19 here uses only 2 ports (only 1 and 2 ports), is there any problem even if it is a floating terminal?

Best Regards

Hi,

Since we do not have details on the internal architecture and the exact function for which Pin 19 is being used, it is better if you don't leave it NC when using CY7C65632.
