DATA Polling
DATA polling is provided to indicate the completion of a
byte write cycle. Once a byte write cycle is initiated,
attempting to read the last byte written will output the
complement of that data on I/O 7 (I/O 0 –I/O 6 are
indeterminate) until the programming cycle is complete.
Upon completion of the self ? timed byte write cycle, all I/O’s
will output true data during a read cycle.

Hardware Data Protection
The following is a list of hardware data protection features
that are incorporated into the CAT28C16A.
1. V CC sense provides for write protection when V CC
falls below 3.0 V min.
2. A power on delay mechanism, t INIT (see AC
characteristics), provides a 5 to 20 ms delay before
a write sequence, after V CC has reached 3.0 V
min.
3. Write inhibit is activated by holding any one of
OE low, CE high or WE high.
4. Noise pulses of less than 20 ns on the WE or CE
inputs will not result in a write cycle.
