AV0708
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 up to 3.5, 7, 14 and 21 seconds, using Aplus 4-bit LOGPCM algorithm.
Key Features
- Single power supply can operate from 2.4V to 6.4V (in this range, user can set Rosc as a fixed value)
- The total voice duration is about 3.5, 7, 14 or 21 seconds those can be partitioned up to 8 voice_sections
- Each voice_section length is flexible
- Voice length can be individually up to 3.5, 7, 14 or 21 seconds at 6kHz S.R
- for each voice_section
- Voice+mute length can be individually up to 11, 21, 21 or 21 seconds at 6kHz sample rate for each voice_section
- Total 16 voice_steps are available for 2 sub_tables
- Each sub_table can only use maximum 8 voice_steps
- For each voice_step, it can specify one voice_section and IO1 output enable options if IO1 is set as an output
- IO1 can be either input or output pin (Mask option)
