DESCRIPTION
aP89341/170/085 series high performance Voice OTP is fabricated with Standard CMOS process with
embedded 8M/4M/2M bits EPROM. It can store up to 341/170/85 sec voice message with 4-bit
ADPCM compression at 6KHz sampling rate. 8-bit PCM is also available as user selectable option.

PIN DESCRIPTIONS
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.
OSC
During voice playback, an external resistor is connect between this pin and the VDD pin to set the
sampling frequency. In OTP Programming Mode, this is the ACLK input signal.
VPP
During voice playback, this pin must be connected together with VDD to the positive power supply
voltage. In OTP Programming Mode, this pin is connected to a separate 6.5V power supply voltage
for EPROM programming.
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.
- In CPU Serial Command Mode, OUT1, OUT2 and OUT3 are fixed as BUSY, POUT and FULL
status output which tell the status of the chip operation. POUT can be further configurable to
BUSYB, 8K, 4K, 2K, 1K, 16Hz, 1M and EMPTY (or FULLB).
- During OTP programming, OUT1 serves as OEB while OUT2 serves as SIO (serial 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
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.

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:
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
Group no.
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 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:

Key Trigger Mode (M1=0, M0=0)
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:

CPU Parallel Trigger Mode (M1=0, M0=1)
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.

C1 is capacitor from 0.1uF to 4.7uF depends on the kind of Vdd source and sound loudness.
Rb is base resistor from 120 Ohm to 390 Ohm depends on Vdd value and transistor gain.
T is an NPN transistor with beta larger than 150.
Reference value for the above components are C = 2.2uF, Rb = 390 Ohm and T = 8050D.
Refer to the Oscillator Resistor Table for suitable value of Rosc.
