DESCRIPTION
The X24256 is a CMOS Serial E
organized 32K x 8. The device features a serial inter-
face and software protocol allowing operation on a
simple two wire bus.

These pins have internal pull downs, so they are read
as LOW if not connected.
A WP pin, when pulled HIGH prevents any nonvolatile
writes to the array. When not connected WP is pulled
LOW, so the device is not normally protected.
