aP89170K dip24/sop28 OTP语音IC芯片 170秒定制专属程序录程序出样快

The aP89682K/341K/170K/085K series are Voice OTP ICs designed for audio playback applications. Below is a concise summary of key features and usage guidelines based on the provided datasheet:

Models & Memory:

aP89682K: 16M bits EPROM, 682 sec playback (6kHz sampling, 4-bit ADPCM).

aP89341K: 8M bits EPROM, 341 sec playback.

aP89170K: 4M bits EPROM, 170 sec playback.

aP89085K: 2M bits EPROM, 85 sec playback.

All support 1023 voice groups and 2016 voice blocks.

Trigger Modes:

Key Mode: Trigger up to 57 voice groups via S1–S8 pins (HIGH/LOW combinations). SBT pin triggers se playback (up to 1023 groups).

CPU Parallel Mode: S1–S8 act as 8-bit addresses (LSB to MSB), with SBT as a strobe.

SPI/I2C Mode: Serial interface for microcontroller integration.

MP3 Mode: Playback control (play/pause, forward/backward) via SBT/S1–S4.

aP89 Modes: Compatibility with older APLUS OTP ICs (Mode 1) or added volume control (Mode 2).

Audio Outputs:

PWM (VOUT1/VOUT2): Directly drive speakers.

DAC (COUT): Requires an external BJT for amplification.

Programmable outputs (OUT1–OUT3) for BUSY, STOP, or LED signals.

Power:

2V–5V supply, standby current<5µA.

VPP must be grounded during playback; connect to 8.5V for OTP programming.

Group 1: Set S1 HIGH, others open (NC).

Group 2: Set S2 HIGH, others NC.

Group 9: Set S1 + S2 HIGH (see page 9 for full mapping).

Use SBT pin to cycle through groups sely (e.g., press once for Group 1, again for Group 2).

Commands: 16-bit data (8-bit command + 8-bit parameters).

Example: PLAY command preloads a voice group address.

VOL++/VOL-- adjust volume (16 levels, max=0, min=15).

Timing: Data latched on rising edge of S2 (SCK), with chip select (S1) active low.

Key Mode Circuit (Page 22):

Connect S1–S8 to buttons, SBT for se playback.

Use COUT with an NPN transistor (e.g., 8050D) and 8Ω speaker.

SPI Mode (Page 24):

Interface with a microcontroller for advanced control (play/pause, volume).

Voice Compression: 4-bit ADPCM (default) saves memory; 16-bit PCM offersuality.

Oscillator Options: Internal resistor, external resistor (68kΩ), or crystal (16MHz).
