X28C256J Description

Short technical summary and product information.

The Intersil X28C256J is a byte alterable E2PROM with a capacity of 32K x 8 bits, operating at a 5-volt supply.

 

This component features robust data protection mechanisms, including hardware and software controls. Hardware features include noise protection, where write cycles are not initiated by WE pulses shorter than 20ns, and a default VCC sense that inhibits write functions when the supply voltage drops below 3.5V. Additionally, holding OE LOW, WE HIGH, or CE HIGH prevents inadvertent writes during power transitions.

 

The device also offers a software-controlled data protection feature. Once enabled via a specific algorithm, this feature protects data from accidental writes even in the powered-up state. The software algorithm requires a three-byte sequence to open a page write window, allowing for the writing of one to sixty-four bytes before automatically returning to the protected state.

 

This E2PROM is suitable for applications requiring reliable non-volatile data storage with enhanced protection against data corruption.
