CAT28C64B Page Write The page write mode of the CAT28C64B (essentially an extended BYTE WRITE mode) allows from bytes of data to be programmed within a single EEPROM write cycle. This effectively reduces the byte-write time by ...

DATA Polling DATA polling is provided to indicate the completion of write cycle. Once a byte write or page write cycle is initiated, attempting to read the last byte written will output the complement of that data on I/O are ...

CAT28C64B HARDWARE DATA PROTECTION The following is a list of hardware data protection features that are incorporated into the CAT28C64B. (1) V sense provides for write protection when V CC falls below 3.5V min. (2) A power on delay mechanism, ...
Page 11
To activate the software data protection, the device must be sent three write commands to specific addresses with specific data (Figure 9). This sequence of commands (along with subsequent writes) must adhere to the page write timing specifications (Figure 11). ...
