OVERVIEW
The S93462 and S93463 are precision power supervi-
sory circuits providing both active high and active low
reset outputs.
Both devices have 1k-bits of E
2
PROM 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.
