10 / 63 page  Signal descriptions M25PX32 10/63 2.6 Write Protect/Enhanced Program supply voltage (W/VPP) W/VPP is both a control input and a power supply pin. The two functions are selected by the voltage range applied to the pin. If the W/VPP input is kept in a low voltage range (0 V to VCC) the pin is seen as a control input. This input signal is used to freeze the size of the area of memory that is protected against program or erase instructions (as specified by the values in the BP2, BP1 and BP0 bits of the Status Register. See Table 9). If VPP is in the range of VPPH (as defined in Table 14) it acts as an additional power supply during the Bulk Erase cycle. In this case VPP must be stable until the Bulk Erase algorithm is completed. 2.7 VCC supply voltage VCC is the supply voltage. 2.8 VSS ground VSS is the reference for the VCC supply voltage. |
