... GENERAL DESCRIPTION: The AVH308 , AV0708 , AV1408 and AV2108 are single-chip voice synthesizing CMOS IC. They are low cost with proper functions and can synthesize voice and 21 seconds, using Aplus 4-bit LOGPCM algorithm. Customer speech data can be programmed into ROM by changing one mask during the device fabrication. Besides, not only a very flexible functions I/O pin is available for the user to apply in various applications, but also an interactive development tool “ ...

... PWM1 and PWM2 can directly drive buzzer ohms speaker. (10). The voice_section length of “voice length + mute length” must be the multiple of 80Hex (AVH308 ) or 100Hex (AV0708 , AV1408 , AV2108 ). (11). In voice_section sequence arrangement (00~07), If there are some voice_sections with only mute and without voice, they should be put next to the last voice_section with voice ...
