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 blockcombinations. 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.

Voice Group Trigger Options: Edge/ Level; Hold / Un-hold; Retrigger / Non-retrigger. Whole Chip Options: Ramp / No-ramp; Output Options; Key / CPU trigger mode. 16ms (@ 8KHz sampling rate) Debounce Time in Key Trigger Mode. 65us (@ 8KHz sampling rate) Debounce Time in CPU Parallel Trigger Mode. RST pin set to HIGH to stop playback at once. Two user programmable outputs for STOP pulse, BUSY signal and flashing LED. Built-inoscillator to control sampling frequency with an external resistor. 2.6V – 5.0V; Wide range single power supply and < 5uA low stand-by current. PWM Vout1 and Vout2 drive speaker directly. D/A COUT to drive speaker through an external BJT. Development System support voice compilation and options selection.
DESCRIPTION
aP8921A/10A series high performance Voice OTP is fabricated with Standard CMOSprocess with embedded 512K/256K bits EPROM. It can store up to 21/10sec voice message with 4-bit ADPCM compression at 6KHz sampling rate. 8-bit PCM is also available as user selectable option. Two trigger modes, simple Key trigger mode and Parallel CPU trigger mode facilitate different user interface. User selectable triggering and output signal options provide maximum flexibility to variousapplications. Built-in resistor controlled oscillator, 8-bit current mode D/A output and PWM direct speaker driving output minimize the number of external components. PC controlled programmer and developing software are available.
