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. om Cus t 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 5.5kHz C 10.5kHz K 5.2kHz D 9.3kHz L 4.9kHz E 8.3kHz M 4.6kHz F 7.5kHz N 4.4kHz G 7.0kHz O 4.1kHz H 6.4kHz P 3.9kHz (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. 1 Rev 1.1 2003/9/18 AVxx16K Series (8). IO1/IO2 have 7 kinds of output option : (A). Stop_High pulse : high active stop pulse output whenever device stop playing. (B). Busy_High active : high active signal output during playing. (C). Busy_Low active : low active signal output during playing. (D). LED 3Hz flash : 3Hz sink signal output for driving LED during playing at 6kHz sample rate. (E). LED 6Hz flash : 6Hz sink signal output for driving LED during playing at 6kHz sample rate. (F). LED dynamic 2/4 : dynamic sink signal output for driving LED during playing. (G). Synchronous output : arbitrary output with voice, user can edit the Sync signal by PowerIO editor. ※ Where (D) and (E) is the LED flash rate at 6kHz sample rate. For different sample rate, the LED flash rate is different from original 3Hz or 6Hz. (9). PWM1 and PWM2 can directly drive buzzer or 8, 16, 32 or 64 ohms speaker. (10). The voice length in voice_section must be the multiple of 200Hex, and the mute length in voice_section must be the multiple of 80Hex. But when the voice length in voice_section of “voice + mute” don’t fully use the last 200Hex, the unused voice length is set as mute and combined with the followed mute time. (11). In pure mute voice_section of M00~M31, the mute length must be the multiple of 80Hex. The maximum mute length is up to 21 seconds at 6kHz sample rate for each mute voice_section. (12). Oscillator selection: (A). External oscillator: Connect OSC pin to Vdd with a resistor, Rosc. (B). Internal oscillator: Connect OSC pin to GND. (Not suggested because of frequency shift and system stability) ※Input Type Description: Option CDS + 1M CDS 1M pull-low Description Normal selection for button trigger. Only 1M pull-low resistance when key-pressed, and 1M+300K(parallel) pull-low resistance when key-released. Internal 300K ohms pull-low resistance, usually for photo-resistor trigger. Internal 1M ohms pull-low resistance, reserve for some special applications. 10M pull-low Internal 10M ohms weak pull-low, usually for touching trigger. Floating No internal resistor connection, usually connected to other output pin or connected to GND by an external resistor. * 10M pull-low option is not available for IO1/IO2 input.
