S-93A46A/56A/66A
The S-93A46A/56A/66A is a high-temperature
operation, high speed, low current consumption, 1 K-
bit, 2 K-bit and 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 and 256-word
×
16-bit in
each. It 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.
