S-93C46B/56B/66B
The S-93C46B/56B/66B is a high speed, low current
consumption, 1/2/4 K-bit serial E
2
PROM with a wide
operating voltage range. It is organized as 64-word
×
16-
bit, 128-word
×
16-bit, 256-word
×
16-bit, respectively.
Each is capable of sequential read, at which time
addresses are automatically incremented in 16-bit
blocks. The instruction code is compatible with the
NM93CS46/56/66.
