AV0716C

Features:

1. Single power supply can operate from 2.4v through 5v.
2. The total voice duration is about 3.5,7,14,21,28,42 seconds could be partitioned up to 16 voice sections. Each voice section could have 4 playing lengths; the longest one is the origional voice+mute length.
3. Voice + mute length could up to 22 seconds ( 11 seconds in AVH316 ) (6k sampling rate) for each voice section.
4. One 112 voice-steps table, could be partitioned up to 16 subtables of steps.
5. 5 mask option of playback speed : 1> 4.3K ; 2> 5.0K ; 3> 6.0K ; 4> 7.5K ; 5> 10.0K ( Hz )
6. 1 trigger input (TG): with resistive schmitt input (270K---1M) for CDS interface. sequential function : once the input was triggered sequentially the device will response by one subtable of voice_step sequentially and cyclically , from subtable_m ( m= 1 -16 ) to user defined subtable_n ( n= 1 - 16 ) . random function : Once the input was trigger , the device will response from subtable_m ( m: 1 - 16 ) to subtable_n ( n: 1 - 16 ) at random .
snooze function : use 2 subtables : 1st stores ringing voice , playing when time's up.
                                                      2nd stores ( greeting sound + ) snooze time .
7.Has two debounce time : 10 ms, 50 us. with following mask option
A>50us B>10ms C>IO1(VDD-50us,GND-10ms) D>IO2(VDD-50us,GND-10ms) E>IO3(VDD-50us,GND-10ms)
C,D,E;could only be selected when IO1,IO2,IO3 are mask_option as control input .
9. Playing mode :EDGEL/LEVEL , HOLD/UNHOLD , RETRIGGER/IRRETRIGGER with following mask options :
EDGE/LEVEL HOLD/UNHOLD RETRIGGERING/IRRETRIGGER
A>EDGE A>HOLD A>IRRETRIGGER
B>LEVEL B>UNHOLD B>RETRIGGER
C>IO1(VDD-edge.GND-level) C>IO1(VDD-hold,GND-unhold) C>IO1(VDD-irretrigger,GND-retrigger)
D>IO2(VDD-edge.GND-level) D>IO2(VDD-hold,GND-unhold) D>IO2(VDD-irretrigger,GND-retrigger)
E>IO3(VDD-edge.GND-level) E>IO3(VDD-hold,GND-unhold) E>IO3(VDD-irretrigger,GND-retrigger)
C, D, E could only be selected when IO1,IO2,IO3 are mask_option as control input .
10. 3 I/O PINS WITH FOLLOWING OPTIONS:
* IO1 * IO2 * IO3
A>COUT B>STOPH C>STOPL A>PWM1 B>STOPH C>STOPL A>PWM2 B>STOPH C>STOPL
D>BUSYH E>BUSYL F>6HZ D>BUSYH E>BUSYL F>6HZ D>BUSYH E>BUSYL F>6HZ
G>DYNA1/4 H>DYN2/4 I>DYN3/4 G>DYNA1/4 H>DYN2/4 I>DYN3/4 G>DYNA1/4 H>DYN2/4 I>DYN3/4
J>USED AS CONTROL INPUT J>USED AS CONTROL INPUT J>USED AS CONTROL INPUT
Item_F : 0.75Hz or 1.5Hz or 3Hz or 6Hz(mask option)
Item_B~I : with one subtable enable status option for IO1, IO2, IO3.
COUT : 3 current output levels, with 4 mask options (1.5mA;3mA;4.5mA;IO3<GND-3mA,VDD-4.5mA>).
PWM1, PWM2 : must be selected on the same time ,direct driving buzzer or 8 or 32 or 64 ohm speaker.
STOPH, STOPL : 40 ms high/low output when device stop playing.(drive 1.8 mA,sink 10mA;3v).
BUSYH, BUSYL : high/low output during device playing (drive 1.8 mA,sink 10mA;3v).
6Hz/3Hz, DYNA1/4, 2/4, 3/4 : LED driving. (drive 1.8 mA, sink 10mA;3v)
Used as control input : internal pull GND (0.5uA,3V)
For all the IO options : the dynamic should choice same level.
If IO2 and IO3 are both at 6Hz(3Hz), they will flash alternatively.
When used as control input, they could be used to control following options by bonding or toggle switch.
EDGE/LEVEL, HOLD/UNHOLD, RETRIGGER/IRRETRIGGER, DEBOUNCE 10ms/50us

Description

The AVH316B, AVH316C, AVH316D, AV0716C, AV0716D, AV1416D, AV2116A, AV2816A is a single-chip synthesizing CMOS VLSI that can synthesize voice up to 3.5,7,14,21,28 seconds using APLUS qualified coding algorithm (LOGPCM).
Customer speech data will be edited and programmed into ROM by changing one mask during one mask during the device fabrication.
