... Page Write Operation The page write feature of the X28HC64 allows the entire memory to be written in 0.25 seconds. Page write allows two to sixty-four bytes of data to be consecutively written to the DESCRIPTION X28HC64 prior to the commencement of the internal Address Inputs programming cycle ...

... Software Data Protection The X28HC64 offers a software controlled data protection feature. The X28HC64 is shipped from Intersil with the software data protection NOT ENABLED; that is, the device will be in the standard operating mode. In this mode data should be protected during power-up/-down operations through the use of external circuits ...

... X28HC64 Because the X28HC64 has two power modes, standby and active, proper decoupling of the memory array is of prime concern. Enabling CE will cause transient current spikes. The magnitude of these spikes is dependent on the output capacitive loading of the I/Os. Therefore, the larger the array sharing a common bus, the larger the transient spikes ...

... Between successive byte writes within a page write operation, OE can be strobed LOW: e.g. this can be done with CE and WE HIGH to fetch data from another memory device within the system for the next write; or with WE HIGH and CE LOW effectively performing a polling operation. 10. The timings shown above are unique to page write operations. Individual byte load operations within the page write must conform to either the controlled write cycle timing ...
