Not applicable

The CY7C0833V data sheet (Doc# 38-06059 Rev. AA, 8/1/2017) notes in fig 1 that the CE and CE/ pins are not applicable for this part and must be tied off to VSS and VDD, respectively [to always enable them].

No such notes are listed in Table 3. Is this device truly intended to be on a bus by itself as it cannot be deselected?

In the Pin definition on Page 6, we try to capture the functionality/

Please have a look at Note 28.

*ISB1, ISB2, ISB3 and ISB4 are not applicable for CY7C0833V because it can not be powered down by using chip enable pins.
