GENERAL DESCRIPTION:
AVxxx-TGx8 Series
The AV0332C, AV0632E, AV0932B, AV0932C, AV1232D, AV1832C, AV2432B, AV3032, AV4232,is a single-chip synthesizing CMOS VLSI that can synthesize voice up to 3,6,9,12,18,24,30,42 seconds ,using APLUS qualified coding algorithm (LOGPCM).Customer speech data will be edited and programmed into ROM by changing one mask during the device fabrication.
Features
:
1. Single power supply can operate from 2.4v through 5v. 2. The total voice duration is about 3, 6, 9, 12, 18, 24, 30, 42 seconds could be partitioned up to 32 voice sections . each voice section could have 4 playing_length , the longest one is the original voice+mute length . 3. Voice + mute length could up to 22 seconds ( 6k sample rate ) for each voice section . 4. One 255 voice-steps table ,could be partitioned up to 32 groups of voice-step . For each voice-step, could specify one length of one voice section and one of 5 levels playback speed and STS1,STS2,STS3, STS4 enable options . playback speed : 1>4.3k ; 2>5k ; 3>6k ; 4>7.5k ; 5>10khz . STS4,3,2,1 enable options : each with one control bit . ( dec to bin ; '0' -> enable , '1' -> disable ) 5. Three mask option trigger input mode : MATRIX , ALONE ( with mode selection ,priority and debounce ) one mode control input 'MODE' , could be used as mode selection or STS4 . ( mask option ) MATRIX : 4x4 matrix inputs ; M1-- M16 ( MODE=0 -> subtable1
- 16 ; MODE=1 -> subtable17
- 32 ) priority : M1>M2>M3>M4 ; M5>M6>M7>M8 ; M9>M10>M11>M12 ; M13>M14>M15>M16 . debounce : 11ms or 1ms . ALONE : 8 alone inputs ; A1 -- A8 ( MODE=0 -> subtable1
- 8 ; MODE=1 -> subtable9
- 16 ) each input could be one of 3 resistive type input : 1>10Mohm to GND ; 2>schmitt (270k
- 1M) for CDS interface ; 3>schmitt ( 270k
- 10M ) for CDS...
