General Description
The AVXX32E -A are series of single-chip synthesizing CMOS VLSI IC which synthesizes voice by LOG_PCM algorithm. Table programming and shared multiple I/O pins make the applications flexible.

FEATUREs
• Operating voltage: 2.4V~5.0V
• One single-key can implement play-all, play-next and random function.
• Maximum play count is 16.
• Each input can implement looping function.
• Single-key input can be last-key priority for stand-alone input or first-key priority.
• Each input trigger can select trigger mode: (For OKY, TG0, TG1, TG3) Edge/Level, Hold/Unhold, Retrigger/Irretrigger.
• Each input trigger can select its own debounce time:
    Fast debounce: < 200us;
    Slow debounce: ~16ms (S.R.=6.0kHz)
• Support bouncing trigger solution for retrigger application. (Second trigger force to retrigger and slow debounce.)
• Maximum table entries are 204*4.
• Word count is only limited by ROM capacity.
• 3 output ports for Status or LED application:
    - OP_A Status:
        Busy_high, DC_low, Stop_high,DC_high
        LED: +Fast,+Slow, Dyn(7/10), Off
    - OP_B Status:
        Busy_high, DC_low, Stop_high, DC_high
        LED: -Fast, -Slow, Dyn(9/10), On
    - OP_C Status: Busy_high, DC_low,
        Busy_low, DC_high
        LED: +Fast, +Slow, On, Off
• Each output can specify its initial state (High or Low)
• Outputs can be set as constant current regardless of the supply voltage varied.
• Two PWM playing ports. Drive speaker or buzzer directly.
• Body define: 3, 7, 14 seconds. (Total ROM size : 18k,42k,84k)
• voice length(3s body:16384*5,7s body:40960*5,14s body:83968*5)
• Voice algorithm: 5-bits LOG_PCM
• External resister for system frequency
• Sixteen default sampling frequencies are supported. The default frequencies can be changed by applying an external resistor.
• Support single key play on/off. (For OKY, TG0, TG1)
• Programmable only pull-low input. (For OKY,TG3)
• Programmable pull-high, pull-low or floating input. (For TG0,TG1)
• TG3_OPC pin can option as input or output by mask option
