AVxx16K Series
1. GENERAL DESCRIPTION:
The AVH316K , AV0716K , AV1416K , AV2116K , AV2816K and AV4216K are single-chip
voice synthesizing CMOS IC. They are low cost with proper functions and can synthesize voice up to 3.5, 7,
14, 21, 28 and 42 seconds, using Aplus 5-bit LOGPCM algorithm. oCmuts er speech data can be
programmed into ROM by changing one mask during the device fabrication. Besides, not only the very
flexible and functional PowerIO pins (IO1/IO2) are available for user to apply in various applications, but also
an interactive development tool “EzSpeech” is ready for user-friendly programming.
2. 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, 21, 28 and 42 seconds those can be partitioned up to 32
voice_sections. Each voice_section length is flexible. Besides, there are additional 32 mute_sections.
(3). Voice length can be individually up to 3.5, 7, 14, 21, 21 and 21 seconds and voice+mute length can be
individually up to 21 seconds at 6kHz sample rate for each voice_section.
(4). Total 96 voice_steps are available for 16 sub_tables. The number of voice_step for each sub_table is
flexible, but maximum is 96. For each voice_step, it can specify one voice_section, playback speed and
IO1/IO2 output enable options if IO1/IO2 are set as output.
(5). Built-in variable oscillator, 16 kinds of playback speed option : ( 3.9k ~ 14.0kHz)
A
14.0kHz
I
6.0kHz
B
12.0kHz
J

(6). IO1 or IO2 can be either input or output pin (Mask option).
(7). Optional “Three Triggers Input” (all OKY, IO1 and IO1 are input), “Two Triggers Input” (OKY and IO1 are
input, IO2 is output), or “One Trigger Input” (OKY is input, IO1 and IO2 are output).
(A). Each input pin has mask options for Edge/Level, Hold/Unhold and Retrigger/Irritrigger trigger modes.
(B). OKY input can choose One-Key Sequential or Random for maximum 16 sub_tables. At One-Key
Sequential, the Reset function of sub_table sequence can be chosen when other keys are triggered.
(C). OKY and IO1 input can choose Toggle On/Off function or not.
(D). OKY input can choose CDS+1M、CDS、1M pull-low、10M pull low or floating input type.
IO1 and IO2 input can choose CDS+1M、CDS、1M pull-low or floating input type.
(E). Each input can choose debounce time: Long debounce for push buttons. Short debounce for fast
switches.
(F). Input pin priority：OKY > IO1 > IO2.
