Features a P89021/010 Standard CMOS process. Embedded 512K/256K bits EPROM. 21/10 Sec Voice Length at 6 KHz sampling and 4-bit ADPCM pression. Maximum 12 voice groups. bination of voice building blocks to extend playback duration. 960 table entries are available for voice block binations. User selectable PCM or ADPCM data press. Two triggering modes are available by whole chip option during voice pilation. - Key Trigger Mode - binations of S1 ~ S4 to trigger up to 12 voice groups; SBT for sequential trigger. - CPU Parallel Trigger Mode - binations 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 for both Key and CPU Trigger Modes. RST pin set to HIGH to stop playback at once. Three user programmable outputs for STOP plus, BUSY signal and flashing LED. Built-in oscillator to control sampling frequency with an external resistor. 2.2V - 3.6V single power supply and < 5u A 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 pilation and options selection. DESCRIPTION a P89021/010 high performance Voice OTP is fabricated with Standard CMOS process with embedded 512K/256K bits EPROM. It can store up to 21/10 sec voice message with 4-bit ADPCM pression at 6KHz sampling...
