S1C88816 TECHNICAL MANUAL
5 PERIPHERAL CIRCUITS AND THEIR OPERATION (Melody Generator)
5.13 Melody Generator
5.13.1 Features and configuration
of melody generator
The S1C88816 has a built-in melody generator for
generating melody signals. General melody
generators often use a ROM to store scale and note
data, therefore melody data cannot be rewritten.
The S1C88816 uses a RAM for this purpose
allowing rewriting of melody data from the
external ports through the CPU.
The principal features are listed below.
Melody RAM size:
Scale RAM
256 words
× 8 bits
(00D000H to 00D0FFH)
Note RAM
256 words
× 8 bits
(00D100H to 00D1FFH)
Number of storable melodies:
Any within the melody RAM
Address control:
Free allocable word size for each melody
Playback output:
1 square-wave tone
Scale (3 octaves):
C4 to G6 with reference to A4 = 440 Hz
C4 to C7# with reference to C4 = 256 Hz
Note:
8 types (half note to sixteenth note)
Tempo:
Selectable from 16 tempos (4 bits)
Reference signal frequency:
32.768 kHz
Driving a piezoelectric buzzer:
MOUT and MOUT are used
MOUT = MOUT = LOW at initial reset
Switching to sound output:
Melody output terminals can be switched for
sound generator output by software
Figure 5.13.1.1 shows the configuration of the
sound generator.
The melody signal generated by the melody
generator is output from the MOUT and MOUT
terminals. Furthermore, the MOUT and MOUT
terminals can output the buzzer signal generated
by the sound generator.
At initial reset, the MOUT and MOUT terminals go
LOW.
Using the two terminals MOUT and MOUT allows
direct driving of a piezoelectric buzzer. In this case,
connect a piezoelectric buzzer between the MOUT
and MOUT via the protective resistors (100
) as
shown in Figure 5.13.1.2.

Fig.5.13.1.2 Direct driving a piezoelectric buzzer
The buzzer can be driven with one terminal by
connecting it to the MOUT terminal via a transistor.
However, direct driving a piezoelectric buzzer is
recommended for lower current consumption.
The CPU accesses the scale RAM and note RAM
individually when data is read and written from/to
the RAM since they have different addresses.
During a melody output, the scale RAM and note
RAM are accessed as a RAM configured with 256
words
× 16 bits.
