Product Summary

The at28c64-25si is a low-power, high-performance 8,192 words by 8 bit nonvolatile Electrically Erasable and Programmable Read Only Memory with popular, easy to use features. The at28c64-25si is manufactured with Atmel reliable nonvolatile technogy. The at28c64-25si is accessed like a Static RAM for the read or write cycles without the need for external components. The at28c64-25si includes two methods for detecting the BUSY end of a write cycle, level detection of RDY/BUSY (unless pin 1 is N.C.) and DATA POLLING of I/O7. The CMOS technology of the at28c64-25si offers fast access times of 120 ns at low power dissipation.
