EPROM
16Kbyte x 8 Bit
This device is an Electrically Programmable Read-Only Memory
(EPROM). It has a size of 128 Kbit, organized as 16384 Words by 8 Bit. The Memory
cells can be selected by 14 address lines and then switched to the data outputs
D0-D7 with OUTPUT ENABLE (/OE). Before that the EPROM must be activated with
CHIP SELECT (/CS).
Memory contents
can be cleared by ultraviolet light, therefore EPROMs have a transparent opening
that is taped over with a Label after programming.
Erased EPROMs can be reprogrammed with an EPROM programmer. The programming voltage
is 12V, a complete programming process takes about 1 to 2 minutes.
Our EPROMs are used, but tested and erased. They are from different
manufacturers, but depending upon availability we consider your special
needs (type, access time, manufacturer… ). We also offer a programming Service
for EPROMs
