... Polling and Toggle status bits signal the start and end of the self−timed write cycle. Additionally, the CAT28C256 features hardware and software write protection. The CAT28C256 is manufactured using ON Semiconductor’s advanced CMOS floating gate technology designed to endure 100,000 program/erase cycles and has a data retention of 100 years. ...

Page Write The page write mode of the CAT28C256 (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 a ...

To activate the software data protection, the device must be sent three write commands to specific addresses with specific data (Figure 10). This sequence of commands (along with subsequent writes) must adhere to the page write timing specifications (Figure 12). ...
