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: 1 Rev 1.0 2003/02/12 AVxx32A Series 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. 2 Rev 1.0 2003/02/12 AVxx32A Series (8).

(9). Oscillator selection: (A). External oscillator: Connect OSC pin to Vdd with a resister, Rosc. (B). Internal oscillator: Connect OSC pin to GND. (C). There are 8 playback speeds for options whether selecting external or internal oscillator. ※ When external Rosc is 180k ohms at 3V, there are 8 kinds of playback speed as in item (4). If you change the value of Rosc, the 8 kinds of playback speed will be changed accordingly and equally. Therefore, you can change the Rosc to change the range of 8 playback_speeds. 3.
