DESCRIPTION

The X28C512/513 is an 64K x 8 E

with Xicor’s proprietary, high performance, floating gate

CMOS technology. Like all Xicor programmable non-

volatile memories the X28C512/513 is a 5V only device.

The X28C512/513 features the JEDEC approved pinout

for bytewide memories, compatible with industry stan-

dard EPROMS.

The X28C512/513 supports a 128-byte page write op-

eration, effectively providing a 39 s/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.
