STR710 power consumption in Stop mode

Hi all,

We are developing a custom board based in STR710, where low power consumption is a must. We need the processor to wake-up quickly so we used STOP mode.

When I put the processor in STOP mode, i switch off the MVR, the pll2, i put all ports in input (so there is no current) and finally i switch off the low-power voltage regulator, hence supplying the voltage externally through V18bkp (Figure 1 of AN2100).

The total power consumption in in STOP mode in the V18bkp pin is 1,57mA. Does anybody have any suggestion for such a huge power consumption?
