PROMs have a built-in power-on-clear circuit that initializes the E
Raise the power supply voltage, starting at 0.2 V maximum, so that the voltage reaches the power supply voltage to
be used within the time defined by t
For example, when the power supply voltage to be used is 5.0 V, t
supply voltage must be raised within 200 ms.
