S-93C46B/56B/66B
CMOS SERIAL E2PROM
The S-93C46B/56B/66B is a high speed, low current
consumption, 1/2/4 K-bit serial E2PROM 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.
