– Vpp Program Supply Voltage (vpp)

Vpp is both a control input and a power supply pin. The two functions are selected by the voltage range

applied to the pin. The supply voltage Vddf and the program supply voltage Vpp can be applied in any

order.

If Vpp is kept in a low voltage range (0V to 3.6V) Vpp is seen as a control input. In this case a voltage

lower than 1V gives protection agains program or block erase, while 1.65V<Vpp<3.6V enables these

functions. Vpp is only sampled at the beginning of a program or block erase; a change in its value after

the operation has started does not have any effect and program or erase opereations continue.

If Vpp is in the range 11.4V to 12.6V it acts as a power supply pin. In this condition Vpp must be stable

until the Program/Erase algorithm is completed.
