OVERVIEW
The S93462 and
S93463 are precision
power supervisory
circuits providing both
active high and active
low reset outputs.
Both
devices have 1k-bits of
E2PROM memory that is
accessible via the
industry standard
microwire bus. The
S93462 is configured
with an internal ORG pin
tied low providing a
8-bit byte organization
and the S93463 is
configured with an
internal ORG pin tied
high providing a 16-bit
word organization. Both
the S93462 and S93463
have page write
capability. The devices
are designed for a
minimum 100,000
program/erase cycles and
have data retention in
excess of 100 years.
