RENESAS X28C512P-12

The X28C512/513 is a 64Kx8 EEPROM, fabricated with Xicor’s proprietary, high performance, floating gate CMOS technology. Like all Xicor programmable nonvolatile memories, the X28C512/513 is a 5V only device. The X28C512/513 features the JEDEC approved pin out for byte wide memories, compatible with industry standard EPROMS. The X28C512/513 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 X28C512/513 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 X28C512/513 supports the software data protection option.
