    KeyPad using Capsense CY8C4245

      I want to design matrix key pad of 48 keys. Currently I am using only One Matrix Button. Is it recommended  to use two Matrix button? If I  use two matrix button then there is any disadvantages there or not?

          If you design consideration doesn't require to have single matrix widget, you can use two widgets. Using two can help when sensor Cp are high. On the other hand the scan duration may increase depending on your implementation : 48 (4x12 ->16, 6x8 -> 14), (4x6x2 -> 20, 8x3x2 -> 22 )
