Description

The CAT35C804A 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 CAT35C804A 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.
