CPU (LSI101: MSM6755B-06)

The CPU contains a sound data ROM and a DAC (Digital to Analog Convertor), and it provides left and right channel sound waveforms in accordance with the pressed key and the selected tone. The following table shows the pin functions of LSI101.

Pin No. Terminal In/Out Function

1 ~ 29 MA14 ~ NC2 — Not used.

30 DGND In Ground (0 V) source 31 DVCC In +5 V source

32, 33 XTLO, XTLI In/Out 20 MHz clock input/output

3 4 NC3 — Not used. Connected to ground. 35 RSTB In Reset signal input 3 6 P24/RXD — Not used. Connected to +5 V. 3 7 P25/TXD — Not used. 38 NMI In Power on signal input. Connected to +5 V. 39 APO Out APO (Auto Power Off) signal output 4 0 NC4 — Not used. 41 REFH Out Terminal for the built-in DAC

42, 43 NC5, NC6 — Not used.

4 4 DAOR Out Right channel sound waveform output 4 5 NC7 — Not used. 46 AVdac In +5 V source for the built-in DAC and ADC 47 DAOL Out Left channel sound waveform output 4 8 REFL Out Terminal for the built-in DAC and ADC 49 AGdac In Ground source for the built-in DAC 50 AGadc In Ground source for the built-in ADC 5 1 ANI — Not used. Connected to ground. 52 AVadc In +5 V source for the internal ADC 5 3 NC8 — Not used. Connected to +5 V. 54 MOD0 In Mode selection terminal

55, 56 MOD1, MOD2 In Mode selection terminal

57 KO9/P40 In APO cancelation signal input 58 ~ 65 KI0/P30 ~ KI7/P37 In Terminals for key/button input signal 66 ~ 73 KO1/P50 ~ KO8/P57 O ut Terminals for key scan signal 74 ~ 77 P20 ~ P23 Out Terminals for button scan signal

7 8 NC9 — Not used.

79 LVCC In +5 V source 80 ~ 8 2 CC1 ~ CC3 Out LED common signal output 83 ~ 87 — — Not used. 88 ~ 95 La ~ Lg, Lp Out LED segment signal output

96 LGND In Ground (0 V) source

97 ~ 100 — — Not used.

FILTER BLOCK

Since the sound signal from the CPU is a stepped waveform, the filter block is added to smooth the waveform.
