DESCRIPTION
The X24641 is a CMOS Serial E
internally organized 8K x 8. The device features a
serial interface and software protocol allowing opera-
tion on a simple two wire bus. The bus operates at
400KHz all the way down to 1.8V.

Hardware Write Protection is provided through a Write
Protect (WP) input pin on the X24641. When the WP
pin is HIGH, the upper quadrant of the Serial E
array is protected against any nonvolatile write
attempts.
