Renesas X28C512JI-15

64K x 8150 нс-40°C ~ 85°C (TA)

Overview

The X28C512/513 is an 64K x 8 E2PROM, 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 pinout for bytewide memories, compatible with industry standard EPROMS. The X28C512/513 supports a 128-byte page write operation, effectively providing a 39ms/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.
