1. INTRODUCTION
SN52010 is a 10 seconds single chip 2-channel voice synthesizer IC which contains
I/O pins and a tiny controller. By programming through the tiny controller, users’
applications including section combination, trigger modes, output status, high
performance melody, multiple voices, and other logic functions can be implemented.

5. FUNCTION DESCRIPTIONS
5.1. Oscillator
SN52010 series accepts crystal oscillator / ceramic resonator or RC type oscillator
(selected by pin CKSEL) for system clock. The typical circuit diagrams for oscillator
are listed as follows.

5.2. ROM
RC Oscillator
SN52010 contains 32K word (10-bit) internal ROM. Program, voices, melodies, data,
and instrument waveforms share the same ROM with the others.
5.3. RAM
SN52010 series contains 64 nibble RAM. The 64 nibble RAM is separated into four
pages (page 0, page1, page2 and page 3). An implicit page indicator is utilized to
specify page address. Four instructions, PAGE0, PAGE1, PAGE2 and PAGE3, can
switch the page indicator. All 16 nibbles of each page can be accessed by direct mode
(to specify M0 ~ M15 in the data transfer type instructions.)
5.4. Power Down Mode
“End” instruction will let SN52010 enter power down mode and consumer very little
amount of current. (<2uA @VDD=3V and <5uA @VDD=5V) After SN52010 enters
power down mode, any valid data transition (LꢁH or HꢁL) occurring on any P3 IO
ports would lead SN52010 back to normal operation mode.
5.5. Sampling Rate Counters
2 independent sampling rate counters are dedicated to 2 individual voice channels to
play voices with different playing rates. The playing rate is programmable from 4KHz
to 40KHz. The resolution of sampling period of each sampling rate counter is 0.25 uS.
This feature helps SN52010 play sounds with accurate pitches in the case of music
instrument synthesis.

5.6. Auto repetition
Auto repetition function helps SN52010 series realize a “looping” sound automatically
by hardware without any software effort. Auto repetition function is a very useful
mechanism to implement “Sustain” sound in instrument synthesis. All 2 channels are
equipped with this function. Arbitrary lengths of looping sound are accepted by
SN52010.
5.7. Wave Mark
This is a new function for SN52010 series, it allows user to add a special mark in wave
data by the voice edit tool “CoolEdit” , ”Goldwav” , “SoundForge” . User can insert
event tags in anywhere of his wave file and can easy to get this special code to do his
special action during voice playing. That means, it should be easily to control the I/O
(such as LED or Motor) and other actions to synchronize with voice.
5.8. Push-Pull output
A Push-Pull Direct Drive circuit is built-in SN52010. The maximum resolution of
Push-Pull is 8 bits (8 bit structure with LSB set to 0). Two huge output stage circuits are
designed in SN52010. With this advanced circuit, the chip is capable of driving
speaker directly without external transistors.
5.9. Volume Control Function
Bit0~Bit2 of VOL Register is applied to control the volume of voice. The relationship
between output current and mode2 register is listed in the following table (power on set
to 111). Bit3 of VOL register provide for VOL Output division 2.

5.10. Watch Dog
The WDT is cascade after system timer. When user reset system timer will issue a
clear signal to WDT also. It would issue a reset signal to chip if user doesn’t reset any
system timer before it reach terminate count (1 Second) when chip is in active mode.
5.11. I/O Ports
P3 is a 4-bit I/O port. Any bit of P3 can be programmed to be input or output
individually. Any valid data transition (HꢁL or LꢁH) of P3 can reactivate the chip
when it is in power-down stage.

5.12. Pull-Low Resister Control
This function provides user to control Pull-Low register of all I/O ports that can be
disabled by user command. With the help of this function, input floating and input pull
low is supported.
