... Page Write The page write operation of the AT28HC64B allows bytes of data to be written into the device during a single internal programming period. A page write operation is initiated in the same manner as a byte write; after the first byte is written, it can then be followed additional bytes. Each successive byte must be loaded within 150 µ ...

... Algorithm” diagram on the entire AT28HC64B will be protected against inadvertent writes. It should be noted that even after SDP is enabled, the user may still perform a byte or page write to the AT28HC64B. This is done by preceding the data to be written by the same 3-byte command sequence used to enable SDP ...
