Hi

   

I'm using the part CY62157EV30LL-45ZXI in 1Mx8bits mode. I understand that I understand BHE, BLE and I/O8 to I/O14 pins are not used (NC). But I also noticed that ISB2 and ICCDR specifications are valid only when /BHE and /BLE signals are tied to CMOS levels. So while operating in 1Mx8bit mode, will the ISB2 and ICCDR specifications be met?

   

Regards,

 When Part is in 1M X8bit mode using BYTE# pin,BHE#, BLE#, IO0 - IO14 can be left floating.

   

ISB2 and ICCDR will be met in this condition for X8 Mode
