APLUS INTEGRATED CIRCUITS 

AVxx16K Series

(8). IO1/IO2 have 7 kinds of output option :

(A). Stop_High pulse : high active stop pulse output whenever device stop playing.

(B). Busy_High active : high active signal output during playing.

(C). Busy_Low active : low active signal output during playing.

(D). LED 3Hz flash : 3Hz sink signal output for driving LED during playing at 6kHz sample rate.

(E). LED 6Hz flash : 6Hz sink signal output for driving LED during playing at 6kHz sample rate.

(F). LED dynamic 2/4 : dynamic sink signal output for driving LED during playing.

(G). Synchronous output : arbitrary output with voice, user can edit the Sync signal by PowerIO editor.

※ Where (D) and (E) is the LED flash rate at 6kHz sample rate. For different sample rate, the LED flash

rate is different from original 3Hz or 6Hz.

(9). PWM1 and PWM2 can directly drive buzzer or 8, 16, 32 or 64 ohms speaker.

(10). The voice length in voice_section must be the multiple of 200Hex, and the mute length in voice_section

must be the multiple of 80Hex. But when the voice length in voice_section of “voice + mute” don’t fully

use the last 200Hex, the unused voice length is set as mute and combined with the followed mute time.

(11). In pure mute voice_section of M00~M31, the mute length must be the multiple of 80Hex. The maximum

mute length is up to 21 seconds at 6kHz sample rate for each mute voice_section.

(12). Oscillator selection:

(A). External oscillator: Connect OSC pin to Vdd with a resistor, Rosc.

(B). Internal oscillator: Connect OSC pin to GND. (Not suggested because of frequency shift and system

stability)

※Input Type Description:

Option

Description

Normal selection for button trigger.

CDS + 1M Only 1M pull-low resistance when key-pressed, and 1M+300K(parallel) pull-low resistance

when key-released.

CDS

Internal 300K ohms pull-low resistance, usually for photo-resistor trigger.

1M pull-low Internal 1M ohms pull-low resistance, reserve for some special applications.

10M pull-low Internal 10M ohms weak pull-low, usually for touching trigger.

Floating

No internal resistor connection, usually connected to other output pin or connected to GND

by an external resistor.

* 10M pull-low option is not available for IO1/IO2 input.

The input type figure is as page 2.
