PROM
S-93C86B
The S-93C86B is a high speed, low current
consumption, 16 K-bit serial E
2
PROM with a wide
operating voltage range. It is organized as 1024-word
×
16-bit, respectively. This product is capable of
sequential read, at which time addresses are
automatically incremented in 16-bit blocks. The
instruction code is compatible with the NM93CS86.
