JEDEC Approved Byte-Wide Pinout
2PROM, fabricated with Xicor’s proprietary, high performance, floating gate CMOS technology. Like all Xicor programmable nonvolatile memories the X28HC64 is a 5V only device. The X28HC64 features the JEDEC approved pinout for bytewide memories, compatible with industry standard RAMs.
The X28HC64 supports a 64-byte page write operation, effectively providing a 32µs/byte write cycle and enabling the entire memory to be typically written in 0.25 seconds.
DATA Polling and Toggle Bit Polling, two methods providing early end of write detection.
In addition, the X28HC64 includes a user-optional software data protection mode that further enhances Xicor’s hardware write protect capability.
2PROMs are designed and tested for applications requiring extended endurance. Inherent data retention is greater than 100 years.
