Functions

Function except a port function

•Apply voltage of 2.7 V – 5.5 V to Vcc, and 0 V to Vss.

•In the flash memory version, apply voltage of 4.0 V – 5.5 V to Vcc, and 0 V to Vss

•This pin controls the operation mode of the chip.

•Normally connected to VSS.

•In the flash memory version, this becomes VPP power source input pin.

•Reference voltage input pin for A-D and D-A converters.

•Analog power source input pin for A-D and D-A converters.

•Connect to VSS.

•Reset input pin for active “L”.

•Input and output pins for the clock generating circuit.

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

the oscillation frequency.

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

pin open.

•8-bit CMOS I/O port.

•A-D converter input pin

•I/O direction register allows each pin to be individually

programmed as either input or output.

•Interrupt input pin

•CMOS compatible input level.

•CMOS 3-state output structure.

•Pull-up control is enabled in a bit unit.

•P20–P27 are enabled to output large current for LED drive.

•8-bit CMOS I/O port.

•D-A converter input pin

•I/O direction register allows each pin to be individually

programmed as either input or output.

•P32 to P33 can be switched between CMOS compat-

ible input level or SMBUS input level in the I2C-BUS

interface function.

•I2C-BUS interface function pins

•Serial I/O3 function pin

•P30, P31, P34–P37 are CMOS 3-state output structure.

•P32, P33 are N-channel open-drain output structure.

•Pull-up control of P30, P31, P34–P37 is enabled in a bit

unit.

•8-bit CMOS I/O port.

•I/O direction register allows each pin to be individually

programmed as either input or output.

(resonator connected)

•Interrupt input pin

•Pull-up control is enabled in a bit unit.

•Serial I/O1 function pin

•Serial I/O1, timer Z function pin

•8-bit CMOS I/O port.

•I/O direction register allows each pin to be individually

programmed as either input or output.

•CMOS compatible input level.

•CMOS 3-state output structure.

•Pull-up control is enabled in a bit unit.

•Serial I/O2 function pin

•Timer X function pin

•Timer Y function pin

•PWM output pin
