6 / 24 page  FEDL2302DIGEST-05 OKI Semiconductor ML2302 6/24 Pin (WCSP) Pin (TQFP) Symbol Type Description J3 61 SIOCK I/O 16-bit serial data transfer clock when external A/D or D/A converter is used. J4 58 VCK I/O Outputs sampling frequency selected. Input pin when slave mode is selected. J7 H7 51 50 XT XT I O Oscillator connection pins. when external clock is used, input clock into XT pin and leave XT pin open. Oscillation stops during reset or power down mode. Figure (a) shows Oscillation Equivalent Circuit. E9 40 RESET I When this pin is “L”, the LSI is initialized and AOUT is set to the GND level. E8 39 FIFOST I When this pin is “L”, EMP, MID, and FULL of playback FIFO can be monitored. When this pin is “H”, EMP, MID, and FULL of record FIFO can be monitored. B3 18 SG O Analog circuit signal ground pin. This pin is connected to GND during reset or power down mode. A4 C4 22 20 MIN LIN I Inverting input pin for built-in OP amplifier. Non-inverting input pin is connected to SG (Signal Ground). B4 A3 21 19 MOUT LOUT O MOUT is the output of internal OP amplifier to MIN, and LOUT is to LIN. A5 25 AOUT O This is the output of the analog playback waveform. H6 52 VOXO O Voice level detection signal H8, B2 49, 16 TEST0, 8 I Pins for testing. Set the pins to “L”. E3, G8 9, 46 DVDD — Digital power supply pin. Insert a minimum 0.1 µF bypass capacitor between this pin and DGND pin D7, G5 38, 57 DGND — Digital GND pin. A2, B8 17, 33 AVDD — Analog power supply pin. Insert a minimum 0.1 µF bypass capacitor between this pin and AGND pin. C5, A8 23, 32 AGND — Analog GND pin. C9, D8 36 35 CB1 CB2 O This pin is used to connect a capacitor for voltage multiplier power supply. Insert a 1 µF capacitor between CB1 and CB2. C8 34 SPVDD O Voltage multiplier power supply output pin for speaker amplifier. Connect a 1 µF capacitor to this pin in order to stabilize the speaker amplifier circuit. D9 37 VR O Bias output pin for speaker amplifier. Set this pin to the GND level during reset or power down mode. A6 26 SPIN I Voice signal input pin for speaker amplifier. B6 27 SPOUT– O Speaker amplifier output pin. This pin outputs a signal in reverse phase to the signal that is input to the SPIN pin. C6 28 SPOUT+ O Speaker amplifier output pin. This pin outputs a signal in phase to the signal that is input to the SPIN pin. D1, D2, D3, C1, C2, B1, B5 10~15 ,24 TEST2 to 7, 9 O Pins for testing. Leave these pins open. |
