Video address: 1.8 yuan. Is the customizable SOP voice chip really that good?
Chip Introduction:

32-bit DSP voice chip, standard SOP8 package.
Built-in 400KByte voice storage space, 8K sampling rate supports up to 400 seconds of voice, supports multiple voice segments, and supports direct drive of a 0.5W speaker.
Currently, there are two versions: a one-wire serial port version and a button control version.
One-wire serial port: Model CHV30, controlled by a microcontroller, supports up to 224 voice segments.

Chip Characteristics

: Power supply voltage VDD: DC2.0-5.5V. Note that there are hardware differences for power supplies below 3.3V.
Standby power consumption is less than 25ua.
16-bit PWM output, can directly drive an 8R/0.5W speaker.
Maximum support for 200 seconds at 16kHz. Maximum support for 400 seconds at 8kHz.

The user manual
only requires the XH2.54 cable to be inserted. Data transmission only requires connecting the DATA pin. If you need to detect the voice playback status, you can do so via the BUSY pin.
Physical Demonstration
Precautions
: 1. When soldering, please pay attention to the soldering order to ensure correct power supply and avoid burning out subsequent circuits! The soldering order should follow the principle of from shortest to smallest, and from inside to outside.
2. It is recommended to use the schematic parameters; the BOM table contains errors.
