Children's toys GPW series voice chip COB/SOP package

The GPW series voice chip is a newly launched industrial-grade OTP voice chip suitable for factory mass production launched by Dongguan Geyuan Electronics Co., Ltd. It has many significant advantages such as low cost, stable performance, high sound quality, convenient control, and simple circuit. Suitable for low-cost and rapid production, and can be shipped in just 1 day. GPW is a stable voice chip that does not require any peripheral circuits and can work normally in extremely harsh noise environments. It has a wide range of temperature and voltage resistance, and the normal operating range is as wide as 1.8V~5.5V, making up for The voice chips currently on the market suffer from poor anti-interference capabilities. The GPW series voice chip has a set of PWM output ports that can directly drive 0.5w speakers with clear sound quality. Built-in LVR reset, no need for external reset circuit. Built-in accurate internal resistance frequency oscillator (+-1% error), no external resistance required. An obvious advantage of GPW is that the OTP burning program can be seamlessly connected with the MASK mask. In other words, users can OTP trial production in the early trial production stage of the product. After successful trial production, when entering mass production, they can directly press the OTP sample MASK masks are put into production to reduce costs, and customers do not need to confirm samples again.
The GPW series voice chip has a variety of key triggering methods, and can output various forms of level signals, and can be set to change the ups and downs of the voice. In addition, GPW supports one-line serial port control by the main control MCU, and can control multiple voice triggers at will. GPW series voice chips have a variety of practical packaging forms: DIP8, DIP14, SOP8, SOP14, etc. The peripheral circuit only requires a power supply coupling capacitor. It works stably, has a wide operating voltage, ultra-low standby power consumption and wide temperature resistance. The performance makes the GPW series voice chips have a cost-effective advantage in a wide range of application fields.

Chip characteristics

OTP storage format, fast production cycle, only one day, no minimum order limit; flexible multiple button operation modes and level output methods to choose from (edge button trigger, level trigger, random button playback, sequential button playback) ;
Simple and convenient two-wire MCU serial port control method, the user’s main control MCU can control the trigger playback and stop of any segment of voice, with BUSY signal output; functions such as power-on loop playback and power-on playback can be set;
It can drive the motor, and the BUSY signal output can be set to play high level, play low level, flash with the rhythm of music, etc. to output voice in various ways: 10 seconds, 35 seconds, 65 seconds, 80 seconds, 115 seconds:

• A set of built-in PWM output can directly drive 0.5W speakers;
