s TERMINAL DESCRIPTION

No. SYMBOL INPUT/OUTPUT

FUNCTION

1 PA0 INPUT/OUTPUT 4-bit Input / Output PORTA.

2 PA1 INPUT/OUTPUT Selects a terminal circuit for PORT grouped with 4 lines from

3 PA2 INPUT/OUTPUT follows by the mask option.

4 PA3 INPUT/OUTPUT

• C-MOS Input Terminal with Pull-up Resistance(IA)

• C-MOS Input Terminal(IC)

• C-MOS Output Terminal(OB)

5 TEST

INPUT

Maker Testing Terminal with Pull-down Resistance

The terminal is recommended to connect to GND.

6 OSC1

7 OSC2

INPUT

OUTPUT

Internal Oscillator Terminals.

Connects a device selected from the ceramic or the crystal

resonator, or the resistor, to these terminals for the internal

oscillator.

In the external clock operation, OSC1 is the external clock

input terminal and OSC2 is normally open terminal.

INPUT

Power Source (0V)

RESET Terminal.

When the low level input-signal, the system is initialized.

10 PB0 INPUT/OUTPUT 1-bit Input / Output PORTB and PORTC.

11 PC0 INPUT/OUTPUT Selects a terminal circuit for each PORT from follows by the

mask option.

• C-MOS Input Terminal with Pull-up Resistance(IA)

• C-MOS Input Terminal(IC)

• Nch-FET Open-Drain Output Terminal with Pull-up

Resistance(OA)

• Nch-FET Open-Drain Output Terminal(OC)

12 PD0 INPUT/OUTPUT 2-bit Input / Output PORTD.

13 PD1

Selects a terminal circuit for PORT grouped with 2 lines from

follows by the mask option.

• C-MOS Input Terminal with Pull-up Resistance(IA)

• C-MOS Input Terminal(IC)

• C-MOS Output Terminal(OB)

When the ports are selected as the input terminal, PD0

operates also as RESTART signal input terminal to return from

STANDBY mode, and PD1 operates also as the Edge

Detector Terminal.

14 PE0 INPUT/OUTPUT 2-bit Input / Output PORTE.

15 PE1 INPUT/OUTPUT Selects a terminal circuit for PORT grouped with 2 lines from

follows by the mask option.

• C-MOS Schmitt Trigger Input Terminal with Pull-up

Resistance(IB)

• C-MOS Schmitt Trigger Input Terminal(ID)

• C-MOS Output Terminal(OB)
