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 input from S1 to S5 and starts the voice playback. - In OTP Programming Mode, this pin is used as PGM signal. VDD Power Supply Pin. VSS Power Ground Pin VOUT1 and VOUT2 Digital PWM output pins which can drive speaker and buzzer directly for voice playback. OSC During voice playback, an external resistor is connected between this pin and the VDD pin to set the sampling frequency. In OTP Programming Mode, this is the ACLK input signal. VPP Connection to VDD is required during voice playback. In OTP Programming Mode, this pin is connected to a separate 6.5V power supply. OUT1, OUT2 and OUT3 - In Key Trigger Mode and CPU Parallel Command Mode, these pins are user programmable pins for the STOP pulse, BUSY and LED signals. - During OTP programming, OUT1 serves as OEB while OUT2 serves as data IO. COUT Analog 8-bit current mode D/A output for voice playback RST Chip reset in playback mode or DCLK pin in OTP programming mode. Ver5.0 4 Aug 23, 2010 Integrated Circuits Inc. aP89042 VOICE SECTION COMBINATIONS Voice files created by the PC base developing system are stored in the built-in EPROM of the aP89042 chip as a number of fixed length Voice Blocks. Voice Blocks are then selected and grouped into Voice Groups for playback. Up to 32 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 aP89042 Memory size 1M bits Max no. of Voice Block 252 No. of bytes per Voice Block 512 Max. no. of Voice Group 32 No. of Voice Table entries 960 Voice Length (@ 6KHz 4-bit ADPCM) 42 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. Voice Group contents Voice Table Entries Group 1 “How are You?” B0 … B12 Group 2 Sound Effect + “How are You?” B13 … B15 + B0 … B12 Group 3 “How are You?” + Music B0 … B12 + B16 … B40 Group 4 Music 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. Ver5.0 5 Aug 23, 2010 Integrated Circuits Inc. aP89042 Programmable Options In both Key Trigger Mode and CPU Parallel Trigger Mode, user can select different trigger functions and output signals to be sent out from the pins OUT1, OUT2 and OUT3. Options affect all Voice Group playback are called Whole Chip Options. Options only affect the playback of individual Voice Group are called Group Options. Whole Chip Options • Key or CPU Parallel Trigger Mode. • 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 beginning 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 and OUT2 to send out different signals during voice playback. Four settings are allowed: OUT1 OUT2 OUT3 Option 1 LED2 LED1 BUSY Option 2 STOP LED1 LED2 Option 3 LED1 BUSY STOP Option 4 LED1 BUSY /BUSY Note: Stop plus and BUSY must be set to enable in order to have STOP plus and BUSY high to come out.

They are: • Edge or Level trigger • Unholdable or Holdable trigger • Re-triggerable or non-retriggerable • Stop pulse disable or enable Fig. 4 to Fig. 9 show the voice playback with different combination of triggering mode and the relationship between outputs and voice playback.

Key or CPU Trigger modes are determined by setting the EPORM programmable options during voice data compilation. Key Trigger Mode With this trigger mode, up to 32 Voice Groups are triggered by setting S1 to S8 to HIGH or NC (not connected) in different combinations. Each Voice Group can have its only independent trigger options (See Fig. 4, 5, 7 and 8 for trigger options definition). Voice Groups can also be triggered sequentially by setting SBT pin to HIGH. CPU Parallel Trigger Mode In this mode, S1 to S5 are set to HIGH or LOW according to the table above and followed by setting the SBT input pin to HIGH, the corresponding Voice Group will be triggered. Trigger options defined in Fig. 4, 5, 7 and 8 are valid for this mode. Fig. 11 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 data input from S1 to S5 into the chip.
