DESCRIPTION
The X28LC512/513 is a low-power 64K x 8 E2PROM,
fabricated with Xicor’s proprietary, high performance,
floating gate CMOS technology. The X28LC512/513
features the JEDEC approved pinout for bytewide memo-
ries, compatible with industry standard EPROMS.
The X28LC512/513 supports 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. The X28LC512/513 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 X28LC512/513 supports the Soft-
ware Data Protection option.
