AVxx08 Series
1.
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 up to 3.
5, 7, 14 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 “EzSpeech” is ready for user-friendly programming.

FEATURES:
(1).
Single power supply can operate from 2.
4V to 6.
4V (in this range, user can set Rosc as a fixed value).
(2).
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.
(3).
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.
(4).
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.
(5).
