5.6.1 Hardware Data Protection

Hardware features protect against inadvertent writes to the AT28BV64B in the following ways:

V_CC power‑on delay – once V_CC has reached 1.8V, the device will automatically time out 10 ms (typical) before allowing a write
Write inhibit – holding any one of OE low, CE high or WE high inhibits write cycles
Noise filter – pulses of less than 15 ns (typical) on the WE or CE inputs will not initiate a write cycle
