CAT28C16A
HARDWARE DATA PROTECTION
The following is a list of hardware data protection fea-
tures that are incorporated into the CAT28C16A.
(1) VCC sense provides for write protection when VCC
falls below 3.0V min.
(2) A power on delay mechanism, t_INIT (see AC charac-
teristics), provides a 5 to 20 ms delay before a write
sequence, after VCC has reached 3.0V 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.
