DESCRIPTION
The X28C512/513 is an 64K x 8 E2PROM, fabricated
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 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.
