X28C512, X28C513
5V, Byte Alterable EEPROM
The X28C512, X28C513 are 64K x 8 EEPROM, fabricated
with Intersil’s proprietary, high performance, floating gate
CMOS technology. Like all Intersil programmable nonvolatile
memories, the X28C512, X28C513 are 5V only devices. The
X28C512, X28C513 feature the JEDEC approved pin out for
byte wide memories, compatible with industry standard
EPROMS.
The X28C512, X28C513 support 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, X28C513 also feature DATA Polling
and Toggle Bit Polling, system software support schemes
used to indicate the early completion of a write cycle. In
addition, the X28C512, X28C513 support the software data
protection option.
