AVXX32A

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: ...
