DESCRIPTION

The CAT33C804A is a 4K-bit Serial E²PROM that safe-

guards stored data from unauthorized access by use of

a user selectable (1 to 8 byte) access code and a

movablememorypointer. Twooperatingmodesprovide

unprotected and password-protected operation allow-

ing the user to configure the device as anything from a

ROM to a fully protected no-access memory. The

CAT33C804A uses a UART compatible asynchronous

protocol and has a Sequential Read feature where data

can be sequentially clocked out of the memory array.

The device is available in 8-pin DIP or 16-pin SOIC

packages.
