Compression Formats: ADPCM4 (4-bit), PCM16 (16-bit uncompressed), PCM8/ULAW8 (8-bit).

Six Triggering Modes: Key, SBT, CPU Parallel, SPI, I2C, and MP3 modes.

Low Power: Standby current 2. Pin Descriptions

Multipurpose Pins:

Se triggering (SBT Mode), address latch (CPU Parallel Mode), or Play/Pause (MP3 Mode).

Key Mode: Trigger up to 9 voice groups.

CPU Parallel Mode: 4-bit address input (S4=MSB, S1=LSB).

SPI/I2C/MP3 Modes: Serve as CSB, SCK, DI, or control buttons.

S1–S4: Function varies by mode:

SBT (Trigger Pin):

M0/M1: Mode selection, volume control, or oscillator configuration.

Power & Ground:

VDDP/VDDA: Power supply (2V–5V).

VSS/VPP: Ground; VPP requires 10kΩ resistor during programming.

3. Triggering Modes

Key Mode:

S1–S4 trigger 9 predefined voice groups via button combinations.

SBT Mode:

Single-button se triggering for 1024 voice groups.

CPU Parallel Mode:

4-bit address input (S1–S4) + SBT strobe for 16 voice groups.

SPI Mode:

3-wire interface (CSB, SCK, DI) for 1024 groups, with commands for Load, Play, Volume, and Power Management.

I2C Mode:

2-wire interface (SCK, DI) with similar functionality to SPI (non-standard I2C implementation).

MP3 Mode:

S1: Backward, S2: Forward, S3: Stop, S4: Reset, SBT: Play/Pause.

Dedicated controls:

4. Advanced Features

Voice Group Options:

Configurable trigger types (Edge/Level), hold/unholdable, retrigger/non-retrigger.

Oscillator Options:

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

Low Voltage Detection (LVD): Prevents malfunction below 1.3V–2.0V.

Reset Circuit: Optional external RC circuit for stability in hot-plug scenarios.

Volume Control: 16/8/4 levels via M0/M1 or serial commands.

5. Technical Specifications

CPU/SPI/I2C Modes: MCU-integrated systems (e.g., IoT devices, industrial controls).

MP3 Mode: Audio players with navigation controls.

Output Configurations:

Direct Speaker Drive: PWM outputs (VOUT1/VOUT2).

External Amplification: COUT with BJT/AMP for higher fidelity.

7. Development Support

Software Tools: PC-based compiler (e.g., 23KW-Software-V2.5) for voice file conversion and EPROM programming.

In-Circuit Programming: VPP pin requires 8.5V and 10kΩ resistor.

8. Package & Dimensions

16-Pin Packages:

300mil DIP and 150mil SOP options.

Bonding Re:

VDDP/VDDA and VSS/VPP must be properly connected for noise immunity.

Key Advantages

Flexibility: Combines multiple voice blocks, supports diverse triggering methods.

Low Power: Ideal for battery-powered devices.

Integration: Minimal external components (oscillator, PWM drive).

Cost-Effective: OTP memory reduces production costs for fixed-voice applications.

This series is suited for consumer electronics, industrial controls, security systems, and IoT devices re embedded voice playback.
