Pin description

ST72324xx-Auto

1. On the chip, each I/O port has eight pads. Pads that are not bonded to external pins are in input pull-up configuration after

reset. The configuration of these pads must be kept at reset state to avoid added current consumption.

2. It is mandatory to connect all available VDD and VAREF pins to the supply voltage and all VSS and VSSA pins to ground.

3. OSC1 and OSC2 pins connect a crystal/ceramic resonator, or an external source to the on-chip oscillator; see

Section 12.6: Clock and timing characteristics for more details.

4. For details refer to Section 12.9.1 on page 162.

Legend / Abbreviations for Table 2:

Type:

I = input, O = output, S = supply

Input level:

A = Dedicated analog input

In/Output level: C = CMOS 0.3VDD/0.7DD

) Output level:

CT = CMOS 0.3VDD/0.7DD with input trigger

HS = 20mA high sink (on N-buffer only)

t(s Port and control configuration:

c Input: float = floating, wpu = weak pull-up, int = interrupt(a), ana = analog ports

Obsolete Product(s) - Obsolete Produ Output: OD = open drain(b), PP = push-pull

a. In the interrupt input column, “eiX” defines the associated external interrupt vector. If the weak pull-up column

(wpu) is merged with the interrupt column (int), then the I/O configuration is pull-up interrupt input, else the

configuration is floating interrupt input.

b. In the open drain output column, ‘T’ defines a true open drain I/O (P-Buffer and protection diode to VDD are not

implemented). See Section 9: I/O ports and Section 12.9: I/O port pin characteristics for more details.
