The Intersil X28C010/X28HT010 is a 128K x 8 EEPROM,fabricated with Intersil's proprietary, high performance,floating gate CMOS technology. Like all Intersilprogrammable non-volatile memories, theX28C010/X28HT010 is a 5V only device. TheX28C010/X28HT010 features the JEDEC approved pin outfor byte-wide memories, compatible with industry standardEEPROMs.The X28C010/X28HT010 supports a 256-byte page writeoperation, effectively providing a 19μs/byte write cycle andenabling the entire memory to be typically written in lessthan 2.5 seconds. The X28C010/X28HT010 also featuresDATA Polling and Toggle Bit Polling, system softwaresupport schemes used to indicate the early completion of awrite cycle. In addition, the X28C010/X28HT010 supportsSoftware Data Protection option.Intersil EEPROMs are designed and tested for applicationsrequiring extended endurance. Data retention is specified tobe greater than 100 years.
