ML63512A/63514A

PIN DESCRIPTIONS

The basic functions of each pin of the ML63512A/63514A are described in Table 1.

A symbol with a slash (/) denotes a pin that has a secondary function.

Refer to Table 2 for secondary functions.

For type, "—" denotes a power supply pin, "I" an input pin, "O" an output pin, and "I/O" an input-

output pin.

For pin, "TB" denotes a 48-pin flat package (48TQFP), and "TP" a 64-pin flat package (64TQFP).

VDDH

CB1

21 27 — Positive power supply pin for external interface (PORT8 supply)

Positive power supply pin for internal logic (internally generated).

27 37 —

A capacitor Cl (0.1 mF) should be connected between this pin and VSS.

Voltage multiplier pin for power supply backup (internally generated).

24 30 —

A capacitor Ch (1.0 mF) should be connected between this pin and VSS.

25 35 — Pins to connect a capacitor for voltage multiplier.

CB2

26 36 — A capacitor (1.0 mF) should be connected between CB1 and CB2.

Low-speed clock oscillation pins.

XT0

28 38 I Crystal oscillation or RC oscillation is selected by the mask option.

If crystal oscillation is selected, connect a crystal between XT0 and

XT1, and connect capacitor (CG) between XT0 and VSS.

XT1

29 39 O If RC oscillation is selected, connect external oscillation resistor

(RCRL) between XT0 and XT1.

Oscillation

High-speed clock oscillation pins.

OSC0

33 43

I Ceramic oscillation or RC oscillation is selected by the mask option.

If ceramic oscillation is selected, connect a ceramic resonator

between OSC0 and OSC1, and connect capacitor (CL0, CL1) between

OSC0 and VSS, OSC1 and VSS.

OSC1 34 44 O If RC oscillation is selected, connect external oscillation resistor

(RCRH) between OSC0 and OSC1.

TST1B 30 40 I Input pins for testing.

Test

TST2B 31 41 I A pull-up resistor is internally connected to these pins.

Reset input pin.

Setting this pin to "L" level puts this device into a reset state.

Reset RESETB 35 45 I Then, setting this pin to "H" level starts executing an instruction

from address 0000H.

An internal or external pull-up resistor is selected by mask option.
