Pinout and pin description

ST92124xxx-Auto/150xxxxx-Auto/250xxxx-Auto

VSS. Digital Circuit Ground. Four pins are available on 100-pin versions, two on 64-pin

versions. The pins are internally connected.

VTEST Power Supply Voltage for Flash test purposes. This pin must be kept to 0 in user

mode.

VREG. Stabilization capacitors for the internal voltage regulator. The user must connect

external stabilization capacitors to these pins. Refer to Figure 16.

2.1

I/O port alternate functions

Each pin of the I/O ports of the ST92124-Auto/150-Auto/250-Auto may assume software

programmable Alternate Functions as shown in Section 4.

2.2

Termination of unused pins

For unused pins, input mode is not recommended. These pins must be kept at a fixed

voltage using the output push pull mode of the I/O or an external pull-up or pull-down

resistor.
