5V, Byte Alterable EEPROM
The Intersil X28C010/X28HT010 is a 128K x 8 EEPROM,
fabricated with Intersil's proprietary, high performance,
floating gate CMOS technology. Like all Intersil
programmable non-volatile memories, the
X28C010/X28HT010 is a 5V only device. The
X28C010/X28HT010 features the JEDEC approved pin out
for byte-wide memories, compatible with industry standard
EEPROMs.
The X28C010/X28HT010 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/X28HT010 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/X28HT010 supports
Software Data Protection option.
Intersil EEPROMs are designed and tested for applications
requiring extended endurance. Data retention is specified to
be greater than 100 years.
