1. GENERAL DESCRIPTION:
The
AVH308
,
AV0708
,
AV1408
and
AV2108
are single-chip voice synthesizing CMOS IC.
They are low cost with proper functions and can synthesize voice up to 3.5, 7, 14 and 21 seconds, using
A
plus 4-bit LOGPCM algorithm. Customer speech data can be programmed into ROM by changing one mask
during the device fabrication. Besides, not only a very flexible functions I/O pin is available for the user to
apply in various applications, but also an interactive development tool "EzSpeech" is ready for user-friendly
programming.
2. FEATURES:
(1). Single power supply can operate from 2.4V to 6.4V (in this range, user can set Rosc as a fixed value).
(2). The total voice duration is about 3.5, 7, 14 or 21 seconds those can be partitioned up to 8 voice_sections.
Each voice_section length is flexible.
(3). Voice length can be individually up to 3.5, 7, 14 or 21 seconds at 6kHz S.R. for each voice_section.
Voice+mute length can be individually up to 11, 21, 21 or 21 seconds at 6kHz sample rate for each
voice_section.
(4). Total 16 voice_steps are available for 2 sub_tables. Each sub_table can only use maximum 8
voice_steps. For each voice_step, it can specify one voice_section and IO1 output enable options if IO1
is set as an output.
(5). Build in oscillator, 15 kinds of playback speed option for internal resistor used : ( 4.0k ~ 18.1kHz)

<Internal oscillator: OSC pad must be bonded to GND>
(6). IO1 can be either input or output pin (Mask option).
(7). Optional "Two Triggers Input" (TG and IO1), or "One Trigger Input" (TG pin only).
(A). Each input pin has mask options for Edge/Level, Hold/Unhold and Retrigger/Irritrigger trigger modes.
(B). TG input can choose CDS+1M
CDS
1M pull-low
10M pull low or floating input type.
(C). IO1 input can choose CDS+1M
CDS
1M pull-low or floating input type.
(D). Debounce time: Long debounce for push buttons. Short debounce for switches. (
In Two Triggers
Input Mode, only one kind of debounce time is available.)
(E). Priority
TG > IO1.
(8). IO1 has the following output option A~F :
(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.
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_section length of "voice length + mute length" must be the multiple of 80Hex
(AVH308
) or
100Hex (
AV0708 , AV1408 , AV2108
).
(11). In voice_section sequence arrangement (00~07), If there are some voice_sections with only mute and
without voice, they should be put next to the last voice_section with voice. Besides, that is not allowed to
put a pure mute voice_section between 2 voice_sections with voice, or put the pure mute voice_section
on first place (00).
(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
CDS + 1M
Normal selection for button trigger.
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 input.
