The X28LC512/513 features the JEDEC approved pinout for bytewide memories, 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 Software Data Protection option.
