MB90550A/550B Series

Pin no.

QFP LQFP

Pin name Circuit type

Function

P51

N-channel open-drain I/O port.

29

27

SCL0

SIN0

G

(NchOD/H)

I2C interface clock I/O pin. This function is enabled with the

I2C interface enabled for operation.

While the I2C interface is operating, place the port output in

the Hi-Z state (PDR = 1).

Extended I/O serial data input pin.

Since this input is used as required while the extended I/O

serial interface is operating for input, the output by any other

function must be off unless used intentionally.

P52,P54

N-channel open-drain I/O ports.

30,32

28,30

SDA1,SDA2

G

(NchOD/H)

I2C interface data I/O pins. This function is enabled with the

I2C interface enabled for operation.

While the I2C interface is operating, place the port output in

the Hi-Z state (PDR = 1).

P53,P55

N-channel open-drain I/O ports.

31,33

29,31

SCL1,SCL2

G

(NchOD/H)

I2C interface clock I/O pins. This function is enabled with the

I2C interface enabled for operation.

While the I2C interface is operating, place the port output in

the Hi-Z state (PDR = 1).

P60 to P67

38 to 41, 36 to 39,

43 to 46 41 to 44 AN0 to AN7

H

(CMOS/H)

General-purpose I/O ports.

A/D converter analog input pin. This function is enabled with

the analog input enabled.

P70 to P77

General-purpose I/O ports.

47,48, 45,46,

53 to 58 51 to 56 IRQ0 to IRQ7

I

(CMOS/H)

External interrupt request input pins.

Since this input is used as required while external interrupts

remain enabled, the output by any other function must be off

unless used intentionally.

P80,P81

General-purpose I/O ports.

59,60 57,58

TIN0,TIN1

J

(CMOS/H)

Reload timer event input pins.

Since this input is used as required while the reload timer is

operating for input, the output by any other function must be

off unless used intentionally.

61,62

59,60

P82,P83

TOT0,TOT1

J

(CMOS/H)

General-purpose I/O ports.

Reload timer output pins.This function is enabled with reroad

timer output enabled.

P84 to P87

General-purpose I/O ports.

63 to 66 61 to 64

IN0 to IN3

J

(CMOS/H)

Input capture trigger input pins.

Since this input is used as required while the input capture

unit is operating for input, the output by any other function

must be off unless used intentionally.

67,68

65,66

P90,P91

OUT0,OUT1

J

General-purpose I/O ports.

(CMOS/H) Output compare event output pins.
