Description
49
DVDD
— Digital power supply pin. Insert a bypass capacitor of 0.1 µF or more between
this pin and the DGND pin.
21
DVDD’
— Digital power supply pin
22
AVDD
—
Analog power supply pin. Insert a bypass capacitor of 0.1 µF or more
between this pin and the AGND pin.
30
DGND
— Digital ground pin
29
AGND
— Analog ground pin
23
SG
24
SGC
O Output pin for analog circuit reference voltage (signal ground)
28
MIN
26
LIN
Inverting input pin of the built-in OP amplifier. Non-inverting input pin is
I
internally connected to SG (signal ground).
27
MOUT
25
LOUT
MOUT and LOUT are output pins of the built-in OP amplifier for MIN and LIN,
O respectively.
This pin is connected to the LOUT pin in the recording mode and to the DA
20
AMON
O converter output in the playback mode. Used to connect the built-in LPF input
(FIN pin).
19
FIN
I Input pin of built-in LPF
17
FOUT
O Output pin of built-in LPF. Used to connect the AD converter input (ADIN pin).
16
ADIN
I Input pin of the built-in 12-bit AD converter
18
AOUT
Output pin of the built-in LPF. This pin outputs playback waveforms and used
O to connect an external speaker drive amplifier.
39
SADX
38
SADY
(Serial Address Data). SADX is used to connect the SAD pin of each external
O serial register and the SADX pin of each external serial voice ROM. SADY is
used to connect the SADY pin of each external serial voice ROM. Outputs of
starting address of read/write.
36
SAS
(Serial Address Strobe). Used to connect the SAS pin of external serial
O register and the SASX and SASY pins of external serial voice ROM. Clock pin
to write the serial address.
(Transfer Address Strobe). Used to connect the TAS pin of each external
37
TAS
serial register and serial voice ROM.
O This pin outputs address strobe outputs to set the serial address data from
the SADX and SADY pins into the internal address counter of each serial
register and serial voice ROM.
(Read/Write Clock). Used to connect the RWCK pin of each external serial
50
RWCK
O
register and the RDCK pin of each external serial voice ROM.
This pin outputs a clock to read data from or write it into each external serial
register.
46
WE
(Write Enable). Used to connect the WE pin of each external serial register.
O This pin outputs WE signal to select either read or write mode.
