� DESCRIPTION

aFRC616 is 16-bits audio processor embedded with 8bits-MCU and 16bits-DSP

engine. It can accomplish 164 minutes with micro sd card(128M bytes) 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 .

Ver. 1.2 3/16

� 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: When compile, SD Card will be requested FORMAT always when insert SD Card

� VOICE OUTPUT

The aFRC616 support PWM and DAC voice output. The PWM mode use VOUT1 and

VOUT2 pin to drive speaker directly without external components.

The DAC mode use 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 larger voice

volume.

The following fig. show circuit for different output methods: PWM, DAC-BJT, DAC-AMP.


Ver. 1.2 4/16

� 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 Level volume control (Default :Maximum volume)

. Support POWER ON LOOP enable/disable

. Support SBT LOOP enable/disable

� 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. 1.2 5/16

� SYSTEM STATE : SBT Mode


Ver. 1.2 6/16

� 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 Level volume control (Default :Maximum volume)

� Typical Application Circuit : (Voice output : PWM)



minimal is 200mA.


Ver. 1.2 7/16

� SYSTEM STATE : MP3 Mode


Ver. 1.2 8/16

� SPI MODE

This SPI mode is specially designed for simple CPU interface. The aFRC616-Micro SD

is controlled by command sent to it from the host CPU.PC3 & PC2 & PC0 are used to

input command word into the chip while PX0 as output from the chip to the host CPU

for feedback response.

a. /CS (PC2): (Chip Select) to initiate the command word input.

b. SCK (PC0): (Serial Clock) to clock-in the command word 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 Level volume control (Default :Maximum volume)

� Typical Application Circuit : (Voice output : DAC)



Ver. 1.2 9/16


minimal is 200mA.

� 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. 1.2 10/16

X: Don't care.

� Play: The Play command is used to play voice.

The Play command is 0101 0000 00-XXXXXX in binary, from bit-15 to bit-0.

X: don’t care.

a. D5 to D0 total 6 bits (0~63) to be the group address.

b. Playing assign group address immediately.

� VOL Ctrl: The Volume control command is used to set volume level.

The VOL Ctrl command is 0101 0110 0000 0-XXX in binary, from bit-15 to bit-0.

X: don’t care.

a. D2 to D0 total 3 bits (0~7) set volume level (max: 7, min: 0).


Ver. 1.2 11/16

� Sleep: The Sleep command is used to power-down the chip.

The Sleep command is 0111 0011 0000 0000 in binary, from bit-15 to bit-0.

a. When the sleep command is executed, the chip enters the standby.

� Wake Up: The Wake Up command is used to power-up the chip.

The Wake Up command is 0111 0111 0000 0000 in binary, from bit-15 to bit-0.

a. When the chip in the standby must be used to the wake up command to power-up.
