POWER SUPPLY CIRCUIT
The power supply circuit generates six voltages as shown in the following table. VDD voltage is always
generated. The others are controlled by APO signal from the CPU.
Name Voltage For operation of
VDD +5 V CPU, Reset IC, DSP, Sound source ROM, Working storage RAM, Effect RAM
DVDD +5 V Power jack, Sustain jack, MIDI jack
AVDD +5V DAC, Filter
LVDD +4.5 V LED Driver
VCC +9 V Power amplifier, Pilot lamp
VC +9 V Power amplifier

RESET CIRCUIT
When batteries are set or an AC adapter is connected, the reset IC provides a low pulse to the CPU. The
CPU then initializes its internal circuit, and clears the working storage RAM.
When the power switch is pressed, the CPU receives a low pulse of POWER signal. The CPU sends
APO signal to supply ground source for the DSP, also sends a reset signal to the DSP.

CPU (LSI105: UPD912GF-3BA)
The 16-bit CPU contains a 1k-byte RAM, three 8-bit I/O ports, two timers, a keycontroller and serial interfaces.
The CPU detects key velocity by counting the time between first-key input signal FI and second-key SI from
the keyboard. The CPU reads sound data and velocity data from the sound source ROM in accordance with
the selected tone; the CPU can read rhythm data simultaneously when a rhythm pattern is selected. Then the
CPU provides 16-bit serial sound data to the DSP. The CPU also controls MIDI input/output and stores
sequencer data into the working storage RAM.
The following table shows the pin functions of LSI105.

DIGITAL SIGNAL PROCESSOR (LSI101: HG51B227FB)
The DSP receives 16-bit serial sound data output from the CPU and adds the selected effect to the sound
data using the effect RAM. Then the DSP provides the sound data to the DAC. The DSP contains two I/O
ports, which controls LEDs.

DAC (IC102: UPD6379GR)
The DAC receives 16-bit serial data output from the DSP. The data contains digital sound data of the
melody, chord, bass, and percussion for the right and left channels. The DAC converts the data into
analog waveforms and output them to each channel separately.
