2 FEATURES 164 minutes in 12KHz & 8-bits playback sample rate. 3V ~ 5V single power supply. 20~25 ua low standby current. Two playback sample rates are allocated :12KHz and 24KHz. 8-bits/16-bits resolution DAC/PWM voice output. Up to 64 voice groups to store wav files. 3 control modes SBT mode, MP3 mode and SPI mode. 8 levels of volume control. 10,000 insertion/removal cycles DESCRIPTION afrc616 is a 16-bits audio processor embedded with 8bits-MCU and 16bits-DSP engine. It can store 164 minutes of data on micro sd card with 1G bits external memory in 12KHz, 8-bits sample rate. User can select play back by 12 KHz or 24 KHz sample rate, 8-bits/16-bits resolution and PWM/DAC voice output. Circuit Block Diagram Ver /15

3 Audio/Voice supports the following voice formats. ULAW8-12K PCM16-12K PCM16-24K Micro SD 1Gb 164min. 82min. 41min. Source file 8bit-12k or higher Mono WAV file Note : The SD card will be reformatted once it is inserted to the PC VOICE OUTPUT The afrc616 supports PWM and DAC voice output. The PWM mode uses VOUT1 and VOUT2 pin to drive speaker directly without external components. The DAC mode uses VOUT2 pin to output current signal. User can use the signal to drive audio amplifier or mix with other components in their applications to provide higher voice volume. The following figure shows the circuit for different output methods: PWM, DAC-BJT, DAC-AMP. Ver /15

4 SBT MODE. SBT Key (PX1) : Play the voice in sequence.. Lock Key (PX2) : Loop Play the voice selected by PX1.. Volume Control (PD2) (vol-) : 8 Levels of volume control (Default :Maximum volume). Support enable/disable POWER ON LOOP. Support enable/disable SBT LOOP Typical Application Circuit : (Voice output : DAC-AMP) *Note: 1. LDO input voltage range minimal is 3V~ 5V. LDO output current range minimal is 200mA. 2. PMOS Gate-Source voltage (VGS) minimal: ±10V, On-State Drain Current (Id(on)) minimal is 200mA. Ver /15

5 SYSTEM STATE : SBT Mode Ver /15

6 MP3 MODE a. Play/Pause key (PX1): Play or Pause all voice groups contents. b. Next key (PX2) : Play all next voice groups contents. c. Volume Control (PD1)(vol+) : Volume up key, d. Volume Control (PD2)(vol-) : Volume down key Note : 8 Levels of volume control (Default :Maximum volume) Typical Application Circuit : (Voice output : PWM) *Note: 1. LDO input voltage range minimal is 3V~ 5V. LDO output current range minimal is 200mA. 2. PMOS Gate-Source voltage (VGS) minimal: ±10V, On-State Drain Current (Id(on)) minimal is 200mA. Ver /15

7 SYSTEM STATE : MP3 Mode Ver /15

8 SPI MODE This SPI mode is specially designed for simple CPU interface. The afrc616-micro SD is controlled by command sent from the host CPU. The pins PC3, PC2 and PC0 are used to input command of data type word into the chip while the PX0 is the output pin from the chip to the host CPU for feedback response. a. /CS (PC2): (Chip Select) to initiate the input command. b. SCK (PC0): (Serial Clock) to clock-in the command at rising edge. c. SDI (PC3): (Data-In) to input the command bits. d. SDO (PC1): (Data-Out) NC e. /BUSY (PX0): (Busy Signal) to feedback response. Note : 8 Levels of volume control (Default :Maximum volume) Typical Application Circuit : (Voice output : DAC) Note: 1. LDO input voltage range minimal is 3V~ 5V. LDO output current range minimal is 200mA. 2. PMOS Gate-Source voltage (VGS) minimal: ±10V, On-State Drain Current (Id(on)) minimal is 200mA. Ver /15

9 SYSTEM STATE : SPI Mode Serial Command Each input command contains 16-bit data. The following list shows the command format and the summary of the available commands: Ver /15

10 Command List Play: The Play command is used to play voice. where D5 to D0 are the 6 bits (0~63) assigned to be the group address. Ver /15

11 VOL Ctrl: The Volume control command is used to set volume level. The VOL Ctrl command is XXX in binary, from bit-15 to bit-0. Where D2 to D0 are the 3 bits (0~7) to set the volume level (max: 7, min: 0). Sleep: The Sleep command is used to power-down the chip. The Sleep command is in binary, from bit-15 to bit-0. When the Sleep command is executed, the chip enters in standby mode Wake Up: The Wake Up command is used to power-up the chip. The Wake Up command is in binary, from bit-15 to bit-0. The Wake Up command is used to power up the chip from standby mode Ver /15
