The S93VP462 and S93VP463 are voltage monitoring memory devices that write protect the array from inadvertent writes whenever VCC is below VTRIP. Both devices have 1k-bits of E2PROM memory that is accessible via the industry standard microwire bus. The S93VP462 is configured with an internal ORG pin tied low providing a 8-bit byte organization and the S93VP463 is configured with an internal ORG pin tied high providing a 16-bit word organization. Both the S93VP462 and S93VP463 have page write capability. The devices are designed for a minimum 1,000,000 program/erase cycles and have data retention in excess of 100 years.
