The X28C512, X28C513 5V, Byte Alterable EEPROM are 64Kx8 EEPROMs fabricated with Intersil's proprietary, high performance, floating gate CMOS technology. They are 5V only devices and support a 128-byte page write operation, effectively providing a 39µs/byte write cycle and enabling the entire memory to be written in less than 2.5 seconds. They also feature DATA Polling and Toggle Bit Polling, system software support schemes used to indicate the early completion of a write cycle.
The Intersil X28C512 and X28C513 are 64K x 8 EEPROM devices fabricated with proprietary high-performance floating gate CMOS technology. These 5V-only devices feature a JEDEC approved pinout compatible with industry standard EPROMs and support a 128-byte page write operation.
