The S-93C46B/56B/66B/76A/86B is high speed, low current
consumption, 3-wire 1/2/4/8 or 16 Kb E

PROM with a wide
operating voltage range. It is organized as 64-word

16 bits respectively. Each is capable of se-
quential read, at which time addresses are automatically
incremented in 16-bit blocks. The instruction code is com-
patible with the NM93CSxx.
These highly reliable E
2
PROM memories feature a guaran-
teed endurance of 1 million cycles over a wide operating
temperature range (−40 to +85°C), data retention of 10
years, and a maximum operating temperature of 105°C.
Built-in data protection functions such as prohibiting write
operations during low-voltage supply and protecting against
write due to erroneous instruction recognition make these
products ideal for storing important data.
The use of a super-small 8-pin SNB package means that
these memories are excellent for small and thin applications
such as mobile devices.
