CAT33C704JTE13中文资料CATALYST数据手册PDF规格书

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