Figure 6.

LQFP/VFQFPN 32-pin pinout

HS stands for high sink capability.

Table 12.

Legend/abbreviation for the pin description table

Type

I= input, O = output, S = power supply

Level

Input

CM = CMOS (standard for all I/Os)

Output

HS = high sink (8 mA)

Output speed

O1 = Standard (up to 2 MHz)

O2 = Fast (up to 10 MHz)

O3 = Fast/slow programmability with slow as default state after reset

O4 = Fast/slow programmability with fast as default state after reset

Port and control

configuration

Input

float = floating, wpu = weak pull-up

Output

T = true open drain, OD = open drain, PP = push pull

Reset state

Bold X (pin state after reset release).

Unless otherwise specified, the pin state is the same during the reset phase (i.e.

“under reset”) and after internal reset release (i.e. at reset state).
