HI, I am considering using the CY62167G in a project, but I need some clarification regarding the "Deselect/Power down" function.

I want to use the part in 2M x8 bit mode.    In this mode,

* I plan to tie /BYTE to ground

* and also tie /BHE and /BLE to VSS (datasheet indicates "not used " and "don't care").

When I look at the truth table on page 16 of the datasheet, the third line looks like an error.  It seems that the /BYTE signal must be "H" to select 1x16M  mode, for the power down mode indicated here.

Can someone confirm that, for row 3 of the truth table, that /BYTE must be HIGH?

thanks

Hi Stephen,

For the third row in the truth table the Byte pin need not be high. It can be X (don't care).

When you are using the SRAM as 2M x 8 configuration, the IO 8 - 14, BLE, BHE  can be left  floating or can be tied GND as per your choice and convenience.

This is applicable to all SRAM parts in our portfolio. I will also provide your feedback to the BU to append the datasheets.

Thanks,

Pradipta.
