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 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.

Frequently the reset controller will be deployed on a PC board that provides a peripheral function to a system.
Examples might be modem or network cards in a PC or a PCMCIA card in a laptop. In instances like this the peripheral
card may have a requirement for a clean reset function to insure proper operation. The system may or may not provide
a reset pulse of sufficient duration to clear the peripheral or to protect data stored in a nonvolatile memory.
The I/O capability of the RESET pins can provide a solution. The systems reset signal to the peripheral can be fed
into the S93462/463 and it in turn can clean up the signal and provide a known entity to the peripherals circuits. The
figure below shows the basic timing characteristics under the assumption the reset input is shorter in duration than
tPURST. The same reset output affect can be attained by using the active high reset input.
