DESCRIPTION

aP89042 high performance Voice OTP is fabricated with Standard CMOS process with embedded 1M
bits EPROM. It can store up to 42 sec voice messages 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 various applications. 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.

PIN DESCRIPTIONS

S1 ~ S8

Input Trigger Pins:

- S1 to S8 is used to trigger the 32 Voice Groups in both Key and CPU Parallel Trigger Mode.

- In OTP Programming Mode, S1 to S7 are used as program enable 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 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.

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.

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.

Group Options

User selectable options that affect each individual group are called Group Options. They are:

• Edge or Level trigger

• Unholdable or Holdable trigger

• Re-triggerable or non-retriggerable

• Stop pulse disable or enable

relationship between outputs and voice playback.

TRIGGER MODES

There are two triggering modes available with aP89042.

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.
