S1 ~ S8 Input Trigger Pins: - In Key Trigger Mode, S1 to S8 is used to trigger the first 32 out of the total 254 Voice Groups . - In CPU Parallel Command Mode, S1 to S8 serve as Voice Group address inputs for 254 Voice Groups with S1 as LSB and S8 as MSB. - In CPU Serial Command Mode, S1 is Chip Select (SC) pin to initiate the command input. S2 is the Serial Clock (SCK) pin which clocks the input command and data bits into the chip. S3 is the Data In (DI) pin in which command and data bits are shifted input into the chip. - In OTP Programming Mode, S1 to S8 are used as data I/O pins. SBT Input Trigger Pin: - In Key Trigger Mode, this pin is trigger pin to trigger the playback of Voice Groups one by one sequentially. - In CPU Parallel Command Mode, this pin is used as address strobe to latch the Voice Group address input at S1 to S8 and starts the voice playback. - In OTP Programming Mode, this pin is used as PGM signal. VDD and AVDD Power Supply Pins: These two pins must be connected together to the positive power supply. VSS and AVSS Power Ground Pins: These two pins must be connected to the power ground. M0 and M1 Operating Mode Setting Pins: - M1=0, M0=0 set the chip into Key Trigger Mode - M1=0, M0=1 set the chip into CPU Parallel Command Mode - M1=1, M0=0 set the chip into CPU Serial Command Mode - M1=1, M0=1 set the chip into OTP Programming Mode VOUT1 and VOUT2 Digital PWM output pins which can drive speaker and buzzer directly for voice playback.

VOICE SECTION COMBINATIONS
AP89341/170/085
Voice files created by the PC base developing system are stored in the built-in EPROM of the AP89341/170/085 chip as a number of fixed length Voice Blocks. Voice Blocks are then selected and grouped into Voice Groups for playback. Up to 254 Voice Groups are allowed. A Voice Block Table is used to store the information of combinations of Voice Blocks and then group them together to form Voice Group. Chip Memory size Max no. of Voice Block Max. no. of Voice Group No of Voice Table entries Voice Length (@ 6KHz 4-bit ADPCM) AP89341 8M bits 2016 254 7680 341 sec aP89170 4M bits 992 254 7680 170 sec aP89085 2M bits 480 254 7680 85 sec
Example of Voice Block Combination Assume here we have three voice files, they are "How are You?", Sound Effect and Music. Each of the voice file is divided into a number of fixed length Voice Block and stored into the memory. Voice File 1 - "How are You?" is stored in Voice Block B0 to B12. Voice File 2 - Sound Effect is stored in Voice Block B13 to B15. Voice File 3 - Music is Voice Block B16 to B40. Voice Blocks are grouped together using Voice Table to form Voice Group for playback: Group no. Group 1 Group 2 Group 3 Group 4 Voice Group contents "How are You?" Sound Effect + "How are You?" "How are You?" + Music Music Voice Table Entries B0 ... B12 B13 ... B15 + B0 ... B12 B0 ... B12 + B16 ... B40 B16 ... B40
Voice Data Compression
Voice File data is stored in the on-chip EPROM as either 4-bit ADPCM or 8-bit PCM format. Voice data stored as 4-bit ADPCM provides 2:1 data compression which can save 50% of memory space. On the other hand, voice data are stored as 8-bit PCM format means no data compression is employed but voice playback quality will be better.

Programmable Options
AP89341/170/085
In Key Trigger Mode (M1=0; M0=0) and CPU Parallel Trigger Mode (M1=0; M0=1), user can select different trigger functions and output signals to be sent out from the pins OUT1, OUT2 and OUT3. Options that affect all Voice Group playback are called Whole Chip Options. Options that only affect the playback of individual Voice Group are called Group Options. Whole Chip Options * Long (16ms) or short (65us) debounce time at 8KHz sampling rate. * Ramp-up-down enable or disable: When COUT is used for playback, Ramp-up-down should be enabled. This function eliminates the `POP' noise at the begin and end of voice playback. When VOUT1 and VOUT2 are used to drive speaker directly, Ramp-up-down should be disabled.
Fig. 1 Ramp-up-down Enable *
Fig.2 Ramp-up-down Disable
Output Options: This option sets up the three output pins OUT1, OUT2 and OUT3 to send out different signals during voice playback. Four settings are allowed: OUT1 Option 1 Option 2 Option 3 Option 4 LED1 STOP LED1 LED1 OUT2 LED2 LED1 BUSY BUSY OUT3 BUSY LED2 STOP BUSYB
Note: BUSY can be set or reset associated with each Voice Block. Stop plus must be set to enable in order to have STOP plus to come out at the end of playback.

TRIGGER MODES
There are three trigger modes available for AP89341/170/085 series which are determined by setting M1 and M2 pins to logic HIGH or LOW. * * * Key Trigger Mode (M1=0; M0=0); CPU Parallel Trigger Mode (M1=0; M0=1); CPU Serial Command Mode (M1=1; M0=0);

Key Trigger Mode (M1=0, M0=0)
AP89341/170/085
With this trigger mode, the beginning 32 Voice Groups are triggered by setting S1 to S8 to HIHG or LOW in different combinations. Each Voice Group can have its only independent trigger options (See Fig. 4, 5, 7 and 8 for trigger options definition). A maximum of 254 Voice Groups are available. The 33rd to 254th Voice Groups can only be triggered one by one sequentially with the SBT key (See Fig. 6 and 9). The setting of S1 to S8 for triggering the 1st to the 32nd Voice Groups are as follow: Voice Group 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 S1 HIGH NC NC NC NC NC NC NC HIGH NC NC NC NC NC NC HIGH HIGH NC NC NC NC NC HIGH HIGH HIGH NC NC NC NC HIGH HIGH HIGH S2 NC HIGH NC NC NC NC NC NC HIGH HIGH NC NC NC NC NC NC HIGH HIGH NC NC NC NC NC HIGH HIGH HIGH NC NC NC NC HIGH HIGH S3 NC NC HIGH NC NC NC NC NC NC HIGH HIGH NC NC NC NC NC HIGH HIGH HIGH NC NC NC NC NC HIGH HIGH HIGH NC NC NC NC HIGH S4 NC NC NC HIGH NC NC NC NC NC NC HIGH HIGH NC NC NC NC NC HIGH HIGH HIGH NC NC NC NC HIGH HIGH HIGH HIGH NC NC NC NC S5 NC NC NC NC HIGH NC NC NC NC NC NC HIGH HIGH NC NC NC NC NC HIGH HIGH HIGH NC NC NC NC HIGH HIGH HIGH HIGH NC NC NC S6 NC NC NC NC NC HIGH NC NC NC NC NC NC HIGH HIGH NC NC NC NC NC HIGH HIGH HIGH NC NC NC NC HIGH HIGH HIGH HIGH NC NC S7 NC NC NC NC NC NC HIGH NC NC NC NC NC NC HIGH HIGH NC NC NC NC NC HIGH HIGH HIGH NC NC NC NC HIGH HIGH HIGH HIGH NC S8 NC NC NC NC NC NC NC HIGH NC NC NC NC NC NC HIGH HIGH NC NC NC NC NC HIGH HIGH HIGH NC NC NC NC HIGH HIGH HIGH HIGH

CPU Parallel Trigger Mode (M1=0, M0=1)
AP89341/170/085
In this mode, S8 to S1 serve as 8-bit addresses input for 254 Voice Groups with S8 represents the MSB and S1 represents LSB. After Group address is set and ready, setting the SBT input pin to HIGH will trigger the corresponding Voice Group to playback. Trigger options defined in Fig. 4, 5, 7 and 8 are valid for this mode.
Fig. 10 CPU Parallel Trigger Mode Note that SBT pin cannot be used as Single Button Sequential trigger in this mode. In stead, it acts as a Strobe input to clock-in the Voice Group address set at S8 to S1 into the chip. Voice Groups are represented in Binary address format. For example: S[8:1] = 0000 0000 (00hex) for Voice Group #1 S[8:1] = 0000 0001 (01hex) for Voice Group #2 *** S[8:1] = 0000 1000 (08 hex) for Voice Group #9 *** S[8:1] = 1000 1000 (88 hex) for Voice Group #137 *** S[8:1] = 1111 1101 (FD hex) for Voice Group #254
CPU Serial Command Mode (M1=1, M0=0) This trigger mode is specially designed for simple CPU interface. The AP89341/170/085 is controlled by command sent to it from the host CPU. S1 to S3 are used to input command word into the chip while OUT1 to OUT3 as output from the chip to the host CPU for feedback response. * * * * * * S1 acts as CS (Chip Select) to initiate the command word input S2 acts as SCK (Serial Clock) to clock-in the command word at rising edge. S3 acts as DI (Data-In) to input the command bits. OUT1 acts as BUSY to indicate the chip is in busy state. OUT2 acts as POUT to output user selected information. OUT3 acts as FULL signal to indicate the Voice Group address buffer is full.
Command input into the chip may contains 8-bit or 16-bit data. The first 8-bit data is command bits while the second 8-bit data (if any) is the Voice Group address data. Table 1 summarize the available commands and their functions.
