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.

Features
Low current consumption
Standby:
1.5
