The Xicor X28C010 is a 128K x 8 E PROM, fabricated
with Xicor's proprietary, high performance, floating gate
CMOS technology. Like all Xicor programmable non-
volatile memories the X28C010 is a 5V only device. The
X28C010 features the JEDEC approved pinout for byte-
wide memories, compatible with industry standard
EPROMs.
The X28C010 supports a 256-byte page write operation,
effectively providing a 19µs/byte write cycle and enabling
the entire memory to be typically written in less than 2.5
seconds. The X28C010 also features DATA Polling and
Toggle Bit Polling, system software support schemes
used to indicate the early completion of a write cycle. In
addition, the X28C010 supports Software Data Protection
option.

Xicor E PROMs are designed and tested for applications
requiring extended endurance. Data retention is specified
to be greater than 100 years.
