DESCRIPTION
The Xicor X2804C is a 512 x 8 E2PROM, fabricated with
an advanced, high performance N-channel floating gate
MOS technology. Like all Xicor Programmable nonvola-
tile memories it is a 5V only device. The X2804C
features the JEDEC approved pinout for byte-wide
memories, compatible with industry standard RAMs,
ROMs and EPROMs.
The X2804C supports a 16-byte page write operation,
typically providing a 300µs/byte write cycle, enabling the
entire memory to be written in less than 640ms. The
X2804C also features DATA Polling, a system software
support scheme used to indicate the early completion of
a write cycle.
Xicor E2PROMs are designed and tested for applica-
tions requiring extended endurance. Inherent data re-
tention is greater than 100 years.
