The X24012 is a CMOS 1024 bit serial E
2
PROM,
internally organized as one 128 x 8 bank. The X24012
features a serial interface and software protocol allow-
ing operation on a simple two wire bus. Three address
inputs allow up to eight devices to share a common two
wire bus.

PROMs are designed and tested for applica-
tions requiring extended endurance. Inherent data re-
tention is greater than 100 years. The X24012 is avail-
able in eight pin DIP and SOIC packages.
