EPROM
8Kbyte x 8 Bit
This device is an Electrically Programmable Read-Only Memory
(EPROM). It has a size of 64 Kbit, organized as 8192 Words by 8 Bit. The Memory
cells can be selected by 13 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 depends upon type 12,5V (27C256) or 21V (27256). The complete
programming process takes about 1 to 2 minutes, depending upon EPROM type.
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
