FEATURES
aP8921A/10A
Standard CMOS process. Embedded 512K/256K bits EPROM. 21/10 sec Voice Length at 6KHz sampling and 4-bit ADPCM compression. Maximum 12 voice groups. Combination of voice blocks to extend playback duration. 960 table entries are available for voice block combinations. User selectable PCM or ADPCM data compression. Two triggering modes are available (EPROM programmable options). - Key Trigger Mode – Combinations of S1 ~ S4 to trigger 12 Voice Groups; SBT sequential trigger is possible. CPU Parallel Trigger Mode – Combinations of S1 ~ S4 with SBT goes HIGH to strobe start the voice playback.
