Type Description  
RST  
VCC  
I/O  
Reset input  
Holding this pin low for 64 oscillator periods while the oscillator  
is running resets the device. The Port pins are driven to their reset  
conditions when a voltage lower than VIL is applied, whether or  
not the oscillator is running.  
This pin has an internal pull-up resistor which allows the device to be reset by  
connecting a capacitor between this pin and VSS.This capacitor is optional  
thanks to the internal POR which output a Reset as long as Vcc has not  
reached the POR threshold level  
Asserting RST when the chip is in Idle mode or Power-down mode  
returns the chip to normal operation.  
The output is active for at least 12 oscillator periods when an internal  
reset occurs.  
XTAL1  
XTAL2  
VCC  
I
Input to the on-chip inverting oscillator amplifier  
To use the internal oscillator, a crystal/resonator circuit is connected  
to this pin.  
If an external oscillator is used, its output is connected to this pin.  
VCC  
O
Output of the on-chip inverting oscillator amplifier  
To use the internal oscillator, a crystal/resonator circuit is connected  
to this pin.  
If an external oscillator is used, XTAL2 may be left unconnected.  
VCC  
LI  
PWR Supply voltage  
VCC is used to power the internal voltage regulators and internal I/O’s.  
PWR DC/DC input  
LI must be tied to VCC through an external coil (typically 4, 7 μH) and provide  
the current for the pump charge of the DC/DC converter.  
CVCC  
DVCC  
PWR Card Supply voltage  
CVCC is the programmable voltage output for the Card interface.  
It must be connected to an external decoupling capacitor.  
PWR Digital Supply voltage  
DVCC is used to supply the digital core and internal I/Os. It is  
internally connected to the output of a 3V regulator and must be connected to  
an external decoupling capacitor.  
EVCC  
VCC  
PWR Extra supply voltage  
EVCC is used to supply the level shifters of UART interface I/O  
pins. It must be connected to an external decoupling capacitor.  
This reference voltage is generated internally (automatically or not),  
or it can be connected to an external voltage reference.  
CVSS  
VSS  
GND DC/DC ground  
CVSS is used to sink high shunt currents from the external coil.
