DESCRIPTION
The X28HC256 is a second generation high perfor-
mance CMOS 32K x 8 E
2
PROM. It is fabricated with
Xicor’s proprietary, textured poly floating gate tech-
nology, providing a highly reliable 5 Volt only nonvolatile
memory.
The X28HC256 supports a 128-byte page write opera-
tion, effectively providing a 24µs/byte write cycle and
enabling the entire memory to be typically rewritten in
less than 0.8 seconds. The X28HC256 also features
DATA Polling and Toggle Bit Polling, two methods of
providing early end of write detection. The X28HC256
also supports the JEDEC standard Software Data Pro-
tection feature for protecting against inadvertent writes
during power-up and power-down.
Endurance for the X28HC256 is specified as a minimum
100,000 write cycles per byte and an inherent data
retention of 100 years.
