Additional preview pages of the AP8821 datasheet.

aP8821 is a high quality voice synthesizer capable of varying playback duration.

A proprietary ADPCM algorithm is used.

The audio message is stored in a 512K bits on-chip EPROM which can store up to 21 seconds of voice data at 6 KHz sample rate.

21 Sec Voice Length at 6 KHz Combination of voice building blocks extends the duration of playback Voice data re-use saves memory space Maximum 14 voice groups 4 trigger pins, S1 to S4 for the 4 voice groups ( group1 ~ 4 ) SBT for sequential playblack for the rest of voice groups & CPU mode trigger CPU trigger mode for all 14 voice groups Holdable, Unholdable, Edge, Level triggering option Debounce time : 21ms ( Key mode ) / 85us (CPU mode ) - 6K sampling rate IRP interrupt pin for master reset.
