� 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 .

� 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 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)
*Note: 1. LDO input voltage range minimal is 3V~ 5V. LDO output current range minimal is 200mA.
