INTEGRATED CIRCUITS INC. aFRC616 Ver. 1.0 8/17 /square6 VOICE OUTPUT The aFRC616 series support 2 voice output modes, PWM and DAC. The PWM mode use VOUT1 and VOUT2 pin to drive speaker directly without external components to save cost. 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, DAC with transistor.
INTEGRATED CIRCUITS INC. aFRC616 Ver. 1.0 9/17 /square6 RESET The aFRC616 can enter standby mode when RSTB pin drive to low. During chip in the standby mode, the current consumption is reduced to I SB and any operation will be stopped, user also can not execute any new operate in this mode. The standby mode will continue until RSTB pin goes to high, chip will be started to initial, and playback “beep” tone to indicate enter idle mode. User can get less current consumption by control RSTB pin especially in some application which concern standby current. /square6 BUSY The MICG pin will be drove to low during the message record or playback, and drove to high during idle or standby, user can detect MICG status to know chip is busy or not. Please note it is limited for MICG pin driving current. Reference to IOH and IOL in section “DC CHARACTERISTICS” . If MICG pin is over loading from external circuit, it will cause noise in microphone circuit.
