AVxx32A Series
1. GENERAL DESCRIPTION:
The AV1232E, AV1832D, AV2432C are single-chip voice synthesizing CMOS IC. They can synthesize
voice up to 12, 18 and 24 seconds, using APLUS 5-bit LOGPCM algorithm. Customer speech data can
be edited and programmed into ROM by changing one mask during the device fabrication.
2. FEATURES:
(1). Single power supply can operate from 2.4V to 5V.
(2). The total voice duration is about 12, 18 or 24 seconds those can be partitioned up to 32 voice_sections.
Each voice_section length is flexible.
(3). Each voice_section can select 4 kinds of End_Address (i.e. 4 kinds of playing_length), the longest
playing_length is the voice+mute length. The voice+mute length can be up to 22 seconds for each
voice_section ( at 6kHz sample rate ).
(4). Total 255 voice_steps are available for 32 sub_tables. For each voice_step, it can specify one
voice_section, one playing_length of voice_section, one kind of playback speed and STS1, STS2, STS3,
STS4 output enable options.
8 kinds of playback speed: 1>5.0k ; 2>5.6k ; 3>6.2k ; 4>7.0k ; 5>8.0k ; 6>9.4k ; 7>11.3k ; 8>14.1k Hz
( With Rosc= 180k ohms at Vdd= 3V )
STS1, 2, 3, 4 output enable options: each output pin with one control bit. ( “0” enable, “1” disable )
(5). Three trigger input mode: MATRIX, ALONE and CPU_INTERFACE. ( Mask option )
In MATRIX and ALONE, there are Mode, Priority and Debounce selections.
One control input pin “MODE/STS4” can be used as Mode selection or STS4. ( Mask option )
MATRIX mode: 4x4 matrix inputs ; M1~M16 (ROW1~4 x COL1~4)
Mode selection: 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 mode: 8 alone inputs ; A1~A8 (ROW1~4 + COL1~4)
Mode selection: Mode=0 subtable1~8 ; Mode=1 subtable9~16
Priority: A1>A2>A3>A4>A5>A6>A7>A8.
Debounce: 10ms or 50us
Each alone input can choose 1M+CDS, 10M or 10M+CDS pull-low input type.
If MODE/STS4 is selected for STS4 output, MATRIX is only subtable1~16 available and ALONE is only
subtable1~8 available.
In these 2 modes, all the trigger input can be assign as different playing mode with following options:

AVxx32A Series
1. ㆒般規格:
AV1232EAV1832DAV2432C,皆為單晶片 CMOS 語音合成 IC。他們以 5-bit LOGPCM 編碼
式,合成長達 121824 秒之語音。藉由製造過程㆗更換光罩,將客戶需要之語音資料編寫入ROM㆗。
2. 特性:
(1). 單㆒工作電壓範圍為2.4 ~ 5 伏特。
(2). 語音總長度可達 121824 秒,且可被分割成32個語音段(voice_section),每段長度可不同。
(3). 每㆒個的語音段可以有㆕種不同的結束點 (即有4種播放時間的選擇),而最長的播放時間是每㆒段語音+
的時間。其㆗每㆒段的語音+靜音時間 最多可達22秒。 (6kHz取樣頻率㆘)
(4). 具有255個語音格(voice_step),可規劃成32語音組(sub_table)。每㆒語音格可指定㆒語音段,播放速度,
STS1STS2STS3STS4 輸出致能或非致能。
8種播放速度選項: 1> 5.0k ; 2> 5.6k ; 3> 6.2k ; 4> 7.0k ; 5> 8.0k ; 6> 9.4k ; 7> 11.3k ; 8> 14.1k Hz
( Vdd=3V ; Rosc=180k ohms )
STS1234 致能選擇: 每㆒種由㆒個控制位元控制( “0” → 致能 ; “1” → 非致能 )
(5). 3種觸發輸入模式: 矩陣 (Matrix) 觸發,單獨 (Alone)觸發,或 串列式CPU觸發。( 光罩選擇 )
在矩陣觸發和單獨觸發模式,各有MODE模式選擇,優先順序以及防止誤動作時間的選項。
”MODE/STS4” 腳可選擇輸入MODE控制模式或 STS4輸出。( 光罩選擇 )
□ 矩陣觸發:4×4矩陣輸入,M1~M16 (ROW1~4 x COL1~4)
MODE模式選擇:MODE=0,對應至語音組1~16MODE=1,對應至語音組17~32
◎優先順序:M1>M2>M3>M4; M5>M6>M7>M8; M9>M10>M11>M12; M13>M14>M15>M16
◎防止誤動作(DEBOUNCE)時間:11ms--提供㆒般手動操作; 1ms--提供較敏感的動作。
□ 單獨觸發:八個單獨輸入,A1~A8 (ROW1~4 + COL1~4)
MODE模式選擇:MODE=0,對應至語音組1~8MODE=1,對應至語音組9~16
◎優先順序:A1>A2>A3>A4>A5>A6>A7>A8
◎防止誤動作(Debounce)時間:10ms--提供㆒般手動操作;50us--提供跳動開關使用。
每個單獨輸入皆可選擇 1M+CDS10M 10M+CDS pull-low 的輸入方式。
如果MODE/STS4腳選擇為STS4輸出,則矩陣觸發只對應至語音組1~16或單獨觸發只對應至語音組1~8
以㆖2種觸發,每㆒輸入可選擇不同觸發方式(光罩選擇):邊緣觸發 / 位準觸發(Edge/Level) ; 保持 / 非保
(Hold/UnHold) ; 後段蓋前段 / 非後段蓋前段(Retrigger/Irretrigger)
□ 串列式CPU觸發:以輸入腳A8 (COL4) 當作連接其它CPU界面的輸入腳,此時其它的輸入腳(ROW1~4,
COL1~3)皆為非致能。
