*COMMENT
Stresses above those listed under "Absolute Maximum Ratings" may cause permanent damage to the device.

Exposure to any absolute maximum rating for extended periods may affect device performance and reliability.




Description

The CAT93C46/56/57/66/86 are 1K/2K/2K/4K/16K-bit Serial E²PROM memory devices which are configured as either registers of 16 bits (ORG pin at VCC) or 8 bits (ORG pin at GND). Each register can be written (or read) serially by using the DI (or DO) pin. The CAT93C46/56/ 57/66/86 are manufactured using Catalyst's advanced CMOS E²PROM floating gate technology. The devices are designed to endure 1,000,000 program/erase cycles and have a data retention of 100 years. The devices are available in 8-pin DIP, 8-pin SOIC or 8-pin TSSOP packages.
