X28C010, X28HT010

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.
