From the oscillation voltage, transformer T501 generates about 600 V which is necessary for lighting the backlight. —... - Page 15 CPU (LSI9: HD6473042F16-465) The 16 bit CPU contains a 512K-bit ROM, a 16K-bit RAM, eleven 8-bit I/O ports, an A/D converter and serial interfaces. The CPU accesses to the RAM1, RAM2, DSP, Key controller, FDD controller and LCD driver LSI. The CPU also controls buttons, LEDs, bender input and MIDI input/output. Pin No.
- Page 16 Pin No. Terminal In/Out Function AC adaptor detection terminal. Modulation signal input. Pedal signal input. FD sheet type (2HD, 2DD) signal input. Key input signal from buttons. LCD contrast control voltage output. AVSS Ground terminal (0 V). Reset signal for DSP, Key controller, FDD controller. Chip select signal for FDD.
- Page 17 DIGITAL SIGNAL PROCESSOR (LSI4:HG51A115A01FD) Upon receipt of note numbers and their velocities, the DSP (Digital Signal Processor) reads sound and velocity data from the sound source ROM in accordance with the selected tone; the DSP can read rhythm data simultaneously when a rythm pattern is selected. Then it provides 16-bit serial signals containing data of the melody, chord, bass, and percussion to the DAC.

- Page 20 KEY TOUCH LSI (LSI10: TC190C020AF-001) By counting the time between first-key input signal FI and second-key SI from the keyboard unit, the key touch LSI detects key velocity of 256-step. Then the LSI sends the CPU the note number and its velocity data.
- Page 21 LCD DRIVER (LSI501: SED1278F2A) The LCD driver can drive a dot matrix LCD having 40 segment and 16 common lines. The LSI contains 240 graphic symbols in the built-in character generator ROM, and stores 80 characters in the built-in display data RAM.
- Page 22 DAC (LSI1: UPD6376GS) UPD6376GS is a two-channel 16-bit Digital to Analog Convertor consisting of resistor string, output ampli- fier and zero offset circuit. 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.
