High Reliability
—Endurance: 100,000 Cycles
—Data Retention: 100 Years
JEDEC Approved Byte-Wide Pinout
DESCRIPTION
The X28HC64 is an 8K x 8 E
2
PROM, fabricated with
Xicor’s proprietary, high performance, floating gate
CMOS technology. Like all Xicor programmable non-
volatile memories the X28HC64 is a 5V only device. The
X28HC64 features the JEDEC approved pinout for byte-
wide memories, compatible with industry standard RAMs.
The X28HC64 supports a 64-byte page write operation,
effectively providing a 32
μ
s/byte write cycle and en-
abling the entire memory to be typically written in 0.25
seconds. The X28HC64 also features
DATA
Polling and
Toggle Bit Polling, two methods providing early end of
write detection. In addition, the X28HC64 includes a
user-optional software data protection mode that further
enhances Xicor’s hardware write protect capability.
Xicor E
2
PROMs are designed and tested for applica-
tions requiring extended endurance. Inherent data re-
tention is greater than 100 years.
