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).

Description
Positive power supply
Negative power supply
Positive power supply pin for external interface (PORT8 supply)
Positive power supply pin for internal logic (internally generated).
A capacitor C
l
(0.1
m
F) should be connected between this pin and V
SS
.
Voltage multiplier pin for power supply backup (internally generated).
A capacitor C
h
(1.0
m
F) should be connected between this pin and V
SS
.
Pins to connect a capacitor for voltage multiplier.
A capacitor (1.0
m
F) should be connected between CB1 and CB2.
Low-speed clock oscillation pins.
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 (C
G
) between XT0 and V
SS
.
If RC oscillation is selected, connect external oscillation resistor
(R
CRL
) between XT0 and XT1.
High-speed clock oscillation pins.
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 (C
L0
, C
L1
) between
OSC0 and V
SS
, OSC1 and V
SS
.
If RC oscillation is selected, connect external oscillation resistor
(R
CRH
) between OSC0 and OSC1.
Input pins for testing.
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.
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.
Melody output pin (non-inverted output)
