Description:
AP89085 is high performance voice OTP, fabricated with standard CMOS process with embedded 2MB EPROM. It can store up to 85 sec voice massage with 4-bit ADPCM compression at 6KHz sampling rate. 8-bit PCM is also available as user selectable . Three triggers modes, simple Key trigger mode and Parallel CPU trigger mode and CPU serial command mode, facilitate difference user interface. User selectable triggering and output signal option provide maximum flexibility to various applications. Built-in resistor controlled oscillator, 8-bit current mode D/A output and PWM direct driving output minimize the number of external components.
Features:
24 PIN DIP
Standard CMOS process
Embedded 2MB EPROM
85 sec voice length at 6KHz sampling rate and 4-bit ADPCM compression
Maximim 254 vocie groups
Combination of voice building blocks to extend playback duration
7680 table entries are available for voice block combinations
User selectable PCM or ADPCM data compress
Three trigger modes are available ( controlled by M1 and M0 ) input pins. Key Trigger Mode - ( M1=0, M0=0 ) S1 ~ S8 to trigger up to 32 voice groups, SBT to trigger up to 256 voice groups sequantially. CPU Parallel Trigger Mode ( M1=0, M0=1 ) S8 ~ S1 services as 8-bits address to trigger up to 256 voice groups with SBT goes HIGH to strobe the address bits. CPU serial command mode - ( M1=1, M0=0 ) in this user command are clocked serially into the chip which enable user to fully control the operation of the chip
Voice group trigger options : Edge / Level : Hold / Unhold : Retrigger / Non-Retrigger
Whole Chip Options : Ramp / No Ramp. Output Options : Key Trigger Mode / CPU trigger mode
16ms or 65us ( @ 8KHz sampling rate ) debounce time
RST pin set to HIGH to stop playback at once
Three User programmable outputs for STOP pulse, BUSY signal and flashing LED
Built - in oscillator to control sampling frequency with an external resistor
2.2V ~ 3.6V single power supply and <5uA low stand-by current
PWM Vout1 and Vout2 drive speaker directly
D/A COUT to drive speaker through and external amplifier
PC controlled programming and developing software available
Development supports voice compilation and options selection
