LQFP64 pin configuration (top view)

3.2

Pad configuration during reset phases

All pads have a fixed configuration under reset.

During the power-up phase, all pads are forced to tristate.

After power-up phase, all pads are forced to tristate with the following exceptions:

●

PA[9] (FAB) is pull-down. Without external strong pull-up the device starts fetching from

flash.

●

PA[8] (ABS[0]) is pull-up.

●

RESET pad is driven low. This is pull-up only after PHASE2 reset completion.

●

JTAG pads (TCK, TMS and TDI) are pull-up while TDO remains tristate.

●

Precise ADC pads (PB[7:4] and PD[11:0]) are left tristate (no output buffer available).

●

Main oscillator pads (EXTAL, XTAL) are tristate.

3.3

Voltage supply pins

Voltage supply pins are used to provide power to the device. Two dedicated pins are used

for 1.2 V regulator stabilization.
