Description

− Apply 2.2 V to 5.5 V to the VCC pin. Apply 0 V to the VSS pin.

− Power supply for the A/D converter.

Connect a capacitor between AVCC and AVSS.

I Input “L” on this pin resets the MCU.

I Connect this pin to VCC via a resistor.

I These pins are provided for XIN clock generation circuit I/O.

Connect a ceramic resonator or a crystal oscillator between

O

the XIN and XOUT pins(1). To use an external clock, input it

to the XIN pin and leave the XOUT pin open.

XCIN clock input XCIN

XCIN clock output XCOUT

I These pins are provided for XCIN clock generation circuit I/O.

Connect a crystal oscillator between the XCIN and XCOUT

O pins(1). To use an external clock, input it to the XCIN pin and

leave the XCOUT pin open.
