DESCRIPTION

The

FT28C512/513

is a 64K x 8 EEPROM, fabricated

with

Force’s

proprietary, high performance, ﬂoating

gate CMOS technology.

The FT28C512/513 is a 5V only

device.

The

FT28C512/513

features the JEDEC

approved pin out for byte wide memories, compatible

with industry standard EPROMS.

The

FT28C512/513

supports 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

FT28C512/513

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

FT28C512/513

supports

the software data protection option.
