Description

Power supply

input

VCC1, VSS

−

Apply 2.7 to 5.5 V to the VCC1 pin and 0 V to the VSS pin. (1, 2)

Analog power

supply input

AVCC

AVSS

VCC1

Applies the power supply for the A/D converter. Connect the

AVCC pin to VCC1. Connect the AVSS pin to VSS.

Reset input

RESET

IVCC1

The microcomputer is in a reset state when applying “L” to the this pin.

CNVSS

(BYTE)

IVCC1

Switches processor mode. Connect this pin to VSS to when after a

reset to start up in single-chip mode. Connect this pin to VCC1 to

start up in microprocessor mode. As for the BYTE pin of the 80-pin

versions, pull-up processing is performed within the microcomputer.

Main clock

input

XIN

VCC1

I/O pins for the main clock generation circuit. Connect a ceramic

resonator or crystal oscillator between XIN and XOUT (3). To use

the external clock, input the clock from XIN and leave XOUT

open.

Main clock

output

XOUT

VCC1

Sub clock input XCIN

VCC1

I/O pins for a sub clock oscillation circuit. Connect a crystal

oscillator between XCIN and XCOUT (3). To use the external

clock, input the clock from XCIN and leave XCOUT open.

Sub clock

output

XCOUT

VCC1

Clock output

CLKOUT

VCC2

The clock of the same cycle as fC, f8, or f32 is outputted.

INT interrupt

input

INT0 to INT2

VCC1

Input pins for the INT interrupt.

NMI interrupt

input

NMI

VCC1

Input pin for the NMI interrupt.

Key input

interrupt input

KI0 to KI3

VCC1

Input pins for the key input interrupt.

Timer A

TA0OUT,

TA3OUT,

TA4OUT

I/O

VCC1

These are Timer A0,Timer A3 and Timer A4 I/O pins. (however,

output of TA0OUT for the N-channel open drain output.)

TA0IN, TA3IN,

TA4IN

VCC1

These are Timer A0, Timer A3 and Timer A4 input pins.

VCC1

Input pin for the Z-phase.

Timer B

TB0IN, TB2IN

to TB5IN

VCC1

These are Timer B0, Timer B2 to Timer B5 input pins.

Serial interface CTS0 to CTS1

VCC1

These are send control input pins.

RTS0 to RTS1

VCC1

These are receive control output pins.

CLK0, CLK1,

CLK3, CLK4

I/O

VCC1

These are transfer clock I/O pins.

RXD0 to RXD2

VCC1

These are serial data input pins.

SIN4

VCC1

This is serial data input pin.

TXD0 to TXD2

VCC1

These are serial data output pins. (however, output of TXD2 for

the N-channel open drain output.)

SOUT3,

SOUT4

VCC1

These are serial data output pins.

CLKS1

VCC1

This is output pin for transfer clock output from multiple pins

function.

I2C mode

SDA0 to SDA2

I/O

VCC1

These are serial data I/O pins. (however, output of SDA2 for the

N-channel open drain output.)

SCL0 to SCL2

I/O

VCC1

These are transfer clock I/O pins. (however, output of SCL2 for

the N-channel open drain output.)
