MB86434

Pin No. Symbol I/O A/D

Description

20 LO0

O D External control latch output pin. Outputs value D0 of address 1000. CMOS

interface.

21 LO1

O D External control latch output pin. Outputs value D1 of address 1000. CMOS

interface.

22 LO2

O D External control latch output pin. Outputs value D2 of address 1000. CMOS

interface.

23 LO3

O D External control latch output pin. Outputs value D3 of address 1000. CMOS

interface.

24 TCLK

I D Tone generator clock input pin. Can be used as a tone CLK signal by using

address 1110 D4D3 to subdivide the internal clock signal by factors of 1/1,

1/2, 1/4. CMOS interface.

25 TONC

I D Tone generator cycle control input pin. CMOS interface. Hlevel signal

outputs tone.

26 LED

O D Ring LED control output pin. CMOS interface.

27 TENV

I A Can be used to generate tone envelope, by placing capacitor between

grounds and turning SW11 on/off.

28 SWO

I/O A Analog switch 10 input/output pin. Controls address 0111 D0.

29 SWI

I/O A Analog switch 10 input/output pin.

30 DSDT

I A Accessory input. Can be connected to RAUD by switching paths.

31 TONEO O A Tone signal output pin.

32 RAUD

O A Output pin for external speaker, or audio test signal. Can be connected to

DSDT by switching paths.

33 VDDSP1 P A Speaker amp power supply pin. To be set within range 4.75 to 5.25 V.

34 JEAR

O A Earphone speaker amp output pin. Capable of 5 mW output at 32 Ω load.

35 XEAR

O A Receiver speaker amp output pin. Internally connected to EAR and BTL.

Maximum output of 10 mW can be obtained at 32 W load by connecting

speaker between EAR and XEAR.

36 EAR

O A Receiver speaker amp output pin. Connected to XEAR and BTL.

37 SPG1

G A Speaker amp ground pin. To be set to 0 V.

38 SPG2

G A Speaker amp ground pin. To be set to 0 V.

39 XTONE O A Speaker amp tone output pin. Internally connected to TONE and BLT.

Maximum output of 10 mW can be obtained at 32 Ω load by connecting

speaker between TONE and XTONE.

40 TONE

O A Speaker amp tone output pin. When speaker amp is not used for tone,

TONE should be shorted to IMTON.

41 IMTON

I A Speaker drive inverted (–) signal input pin. Can be used to adjust gain by

connecting resistance to TONE and IMTON.

42 VDDSP2 P A Speaker amp power supply pin. To be set within range 4.75 to 5.25 V.
