Pin description
ST7260xx
10/139
RESET (see Note 1): Bidirectional. This active low signal forces the initialization of the MCU.
This event is the top priority non maskable interrupt. This pin is switched low when the
Watchdog is triggered or the VDD is low. It can be used to reset external peripherals.
OSCIN/OSCOUT: Input/Output Oscillator pin. These pins connect a parallel-resonant
crystal, or an external source, to the on-chip oscillator.
VDD/VSS (see Note 2): Main power supply and ground voltages.
VDDA/VSSA (see Note 2): Power supply and ground voltages for analog peripherals.
Alternate functions: Several pins of the I/O ports assume software programmable
alternate functions as shown in the pin description.
Note:
1
Note 1: Adding two 100 nF decoupling capacitors on the Reset pin (respectively connected
to VDD and VSS) will significantly improve product electromagnetic susceptibility
performance.
2
To enhance the reliability of operation, it is recommended that VDDA and VDD be connected
together on the application board. This also applies to VSSA and VSS.
3
The USBOE alternate function is mapped on Port C2 in QFN40 devices. In SO24 devices it
is mapped on Port B1.
4
The timer OCMP1 alternate function is mapped on Port A6 in QFN40 pin devices. In SO24
devices it is not available.
Legend / abbreviations for Figure 2, Figure 3 and Table 2, Table 3:
Type:
I = input, O = output, S = supply
In/Output level: CT = CMOS 0.3 VDD / 0.7 VDD with input trigger
Output level:
10 mA = 10 mA high sink (Fn N-buffer only)
25 mA = 25 mA very high sink (on N-buffer only)
Port and control configuration:
Input:
float = floating, wpu = weak pull-up, int = interrupt
Output:
OD = open drain, PP = push-pull, T = True open drain
The RESET configuration of each pin is shown in bold. This configuration is kept as long as
the device is under reset state.
