*COMMENT
Stresses above those listed under "Absolute Maximum Ratings" may cause permanent damage to the device. These are stress ratings only, and functional operation of the device at these or any other conditions outside of those listed in the operational sections of this specification is not implied. Exposure to any absolute maximum rating for extended periods may affect device performance and reliability.


Description

The CAT33C704 is a 4K-bit Serial E²PROM that safeguards stored data from unauthorized access by use of a user selectable (1 to 8 byte) access code and a movable memory pointer. Two operating modes provide unprotected and password-protected operation allowing the user to configure the device as anything from a ROM to a fully protected no-access memory. The CAT33C704 uses a unique serial-byte synchronous communication protocol and has a Sequential Read feature where data can be sequentially clocked out of the memory array. CAT33C704 is available in 8-pin DIP or 16-pin SOIC packages.
