S93463P2.7A Datasheet PDF - Summit Microelectronics

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.
