Notes: (1) Typical values are at V
CC=5.0V,TA=25
°C and specified loading.
(2) CS and WE above are accessed through CS1~4 and WE1~4 respectively. These inputs must be operated
simultaneously for 32 bit mode, in pairs for 16 bit mode and singly for 8 bit mode.

Notes
(1) Stresses above those listed may cause permanent damage to the device. This is a stress rating only and
functional operation of the device at these or any other conditions above those indicated in the operational
sections of this specification is not implied. Exposure to absolute maximum rating conditions for extended periods
may affect device reliability.
