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.

DescriptionThe 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.
Powerful functions and pure speech architecture make the AVXX32E -A series are able to best fit most speech applications and a best cost/performance ratio as a result. The programming of the AVXX32E -A series is first to define words. Each word contains voice data (or mute length), output method, assemble the words into sentences first, and then the programmer can assign the sentences to the keys corresponding to the user inputs.
The TG3_OPC pin of the AVXX32E -A series is multiplexed. This means it can option as input pin or output pin.
