CAT33C804A Datasheet 4k-bit Secure ACcess Serial E2prom

Manufacturer: Catalyst Semiconductor

Overview: Preliminary CAT33C804A 4K-Bit Secure Access Serial E2PROM.

General Description

The CAT33C804A 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 CAT33C804A uses a UART compatible asynchronous protocol and has a Sequential Read
