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:

Edege/Level; Hold/UnHold; Retrigger/Irretrigger.
□ CPU_INTERFACE mode: Addressing access mode by input pulse count. In this mode, A1~A7
(ROW1~4, COL1~3) are disable, A8 (COL4) can be access up to 32 subtables.
(6). The A8 or M16 can be selected as NORMAL, SEQUENTIAL or CPU_INTERFACE. ( Mask option )
□ NORMAL: normal mode as in item (5).
□ SEQUENTIAL: can be selected to combine with MODE input or not. ( Mask option )
(A). If A8 or M16 is in SEQUENTIAL and is combined with MODE input:
MODE=0 : the device will response by one subtable sequentially and cyclically, from subtable1 to
user defined end subtable (subtable n, n=1~16).
MODE=1 : the device will response by one subtable sequentially and cyclically, from subtable 17
to user defined end subtable (subtable n, n=17~32).
The number of subtables (used in sequence) in MODE=1 and MODE=0 must be equal; this
number must be less than 16.
(B). If A8 or M16 is in SEQUENTIAL and is not combined with MODE input:
The device will response by one subtable sequentially and cyclically, from subtable1 to user
defined end subtable (subtable n, n=1~32).
The relationship between SEQUENTIAL ( A8/M16 ) and other inputs ( A1~A7 / M1~M15 ) can be
selected as RESET or UNRESET. ( Mask option )
◎ RESET: once the other inputs are triggered, the SEQUENTIAL sequence will reset to subtable 1.
◎ UNRESET: SEQUENTIAL sequence and other inputs are independent.
(7). Four STS pins have the following options: ( Mask option )
□ OUT1: Cout (Current output) or STS1 output
□ OUT2: PWM1 or STS2 output
□ OUT3: PWM2 or STS3 output
□ MODE/STS4: MODE selection or STS4 output
Cout has 3 current output levels: 1>1.5mA ; 2>3mA ; 3>4.5mA. ( full scale ; Vdd=3V )
PWM1 and PWM2 must be selected on the same time, they can directly drive buzzer or 8, 16, 32 or 64
ohms speaker.
