VPP Program Supply Voltage (12V). VPP is both

a control input and a power supply pin. The two

functions are selected by the voltage range ap-

plied to the pin; if VPP is kept in a low voltage range

(0 to 2V) VPP is seen as a control input, and the

current absorption is limited to 5µA (0.2µA typical).

In this case with VPP = VIL we obtain an absolute

protection against program or erase; with VPP =

VPP1 these functions are enabled (see Table 26).

VPP value is only sampled during program or

erase write cycles; a change in its value after the

operation has been started does not have any ef-

fect and program or erase are carried on regularly.

If VPP is used in the 11.4V to 12.6V range (VPPH)

then the pin acts as a power supply (see Table

26). This supply voltage must remain stable as

long as program or erase are running. In read

mode the current sunk is less then 0.5mA, while

during program and erase operations the current

may increase up to 10mA.

VSS Ground. VSS is the reference for all the volt-

age measurements.
