— 3 — CIRCUIT DESCRIPTION CPU(HD6433298A16P : H8/329) The 16-bit CPU contains a 32K-byte ROM, a 1K-byte RAM, an 8-bit A/D converter, timers and I/O ports. The CPU accesses to the DSP, Key Touch LSI, RAM, buttons and LEDs. But the CPU directly receives MIDI and pedal signals.
— 4 — DIGITAL SIGNAL PROCESSOR, LSI-S (HG51A115A01FD) The LSI-S is a 16-bit DSP(Digital Signal Processor) and accessable to 16M-bit sound source ROM and to 64K- bit RAM. The DSP can read data of 32 polyphonic note from the ROM and provides two 16-bit serial dat with timing signals to each channel's D/A converter.
— 5 — KEY TOUCH LSI(HG52E35P) By counting the time between the first key input signal FI and the second SI from the keyboard unit, the key touch LSI detects key velocity of 256-step. Then the LSI sends the CPU note numbers and their velocities. Pin No.
— 6 — POWER AMPLIFIER(LA4598) LA4598 is 2-channel power amplifier with standby switch. Pin No. Terminal In/Out Function 1 Power GND In Ground(0V) source. 2 Ch1 B.S. - Terminal for bootstrap capacitor. 3 Ch1 OUT O u t Channel 1 output. 4 VCC I n +9V source.
