Function

Function except a port function

• Apply voltage of 3.0 V to 5.5 V to VCC, and 0 V to VSS.

(Extended operating temperature version : 4.0 V to 5.5 V)

(High-speed version : 2.7 V to 5.5 V)

CNVSS

CNVSS

• This pin controls the operation mode of the chip.

• Normally connected to VSS.

• If this pin is connected to VCC, the internal ROM is inhibited and external memory is accessed.

VREF

Analog reference • Reference voltage input pin for A-D and D-A converters

voltage

AVSS

______

RESET

Analog power

source

Reset input

• GND input pin for A-D and D-A converters

• Connect to VSS.

• Reset input pin for active “L”

XIN

XOUT

Clock input

Clock output

• Input and output signals for the internal clock generating circuit.

• Connect a ceramic resonator or quartz-crystal oscillator between the XIN and XOUT pins to set the

oscillation frequency.

• If an external clock is used, connect the clock source to the XIN pin and leave the XOUT pin open.

• The clock is used as the oscillating source of system clock.

I/O port P0

I/O port P1

I/O port P2

I/O port P3

• 8 bit CMOS I/O port

• I/O direction register allows each pin to be individually programmed as either input or output.

• At reset this port is set to input mode.

• In modes other than single-chip, these pins are used as address, data, and control bus I/O pins.

• CMOS compatible input level

• CMOS 3-state output structure
