PROM
S-29LXX0A Series
The S-29LXX0A Series is low power 1K/2K/4K-bit E
2
PROM with a low
operating voltage range. They are organized as 64-word
×
16-bit, 128-
word
×
16-bit and 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 NM93CSXX
Series.
