KT148A Voice Chip: A Powerful Tool to Enhance the User Experience of Smart Soymilk Makers

The KT148A voice chip from Qingyue Electronics significantly enhances the user experience of smart soymilk makers with its unique advantages. It has a large - capacity voice storage space, allows users to change voices by themselves, features a low - power design, and can be reprogrammed.

Smart soymilk makers emerged from modern people's pursuit of a healthy lifestyle and a convenient home life. In the fast - paced urban life, soy milk is popular among consumers of all ages due to its rich nutrition and easy absorption. With the advancement of technology and the popularity of intelligence, smart soymilk makers not only meet the demand for a healthy diet but also integrate elements of convenient operation and intelligent experience. The KT148A voice chip adds a voice - broadcasting function to it, further improving the user experience.

The KT148A is a 32 - bit DSP voice chip with a standard SOP8 package. It has an internal 420KByte voice space, can support a maximum voice length of 420 seconds, supports multi - segment voices, can directly drive a 0.5W speaker, and allows users to change voices independently.

Chip Advantages

1. High Cost - effectiveness: Compared with traditional OTP chips, the process improvement reduces costs, and it can be reprogrammed.

2. Convenient Voice Replacement: Users can change voices by themselves through the computer - side serial port without expensive tools.

3. High - quality Sound Pursuit: The chip has sufficient built - in space to achieve a higher sound quality effect.

Functional Features

1. Built - in Flash Memory: With an ultra - small SOP8 package, it has a built - in 420KByte voice storage space, supports multi - segment voice storage of up to 420 seconds, ensures smooth voice broadcasting, simplifies hardware design, reduces costs and integration application difficulties, and is easy for engineers to get started.

2. User - changeable Voice: The firmware of the chip opens this function, enabling flexible voice customization, such as "Welcome to use XXX intelligent voice soymilk maker", "Turn on the power", etc.

3. High - quality Sound Playback: It uses advanced audio processing technology to ensure clear and natural voice broadcasting, avoiding misunderstandings or operational errors caused by poor sound quality.

4. Low - power Design: The standby power consumption is less than 25ua. Optimized for the energy - saving needs of smart home appliances, the power consumption in the low - power mode is less than 1.5uA, extending the service life of the soymilk maker and conforming to the modern family's pursuit of environmental protection and energy - saving.

Application

The KT148A chip is applied to smart soymilk makers, with clear sound, loud volume, simple operation, and no pressure on lithium - battery power supply.

Reasons for Engineers to Select the Chip

1. It is a 32 - bit DSP voice chip with an internal oscillation of 5MHZ and a PLL up to 120MHZ.

2. The operating voltage is 2.0 - 5.5V, and there are hardware details differences when the power supply is less than 3.3V.

3. The standby power consumption is less than 25ua, and there is a low - power mode of 1.5uA.

4. It has a 16 - bit PWM output and can directly drive an 8 - ohm / 0.5W speaker.

5. It provides tools to convert audio formats by oneself, and the operation is simple.

6. It can support up to 200 seconds at 16KHZ and up to 400 seconds at 8KHZ.

7. Customers can directly change the voice content through the computer - side tool software and the serial port.

8. It supports one - wire serial port control and can customize various protocols as needed.

9. It supports 224 - segment addresses and can be expanded as required.

10. It has hardware iic and UART interfaces and can customize various functions for customers.

11. The chip can be reprogrammed, so there is no need to worry about batch problems caused by incomplete testing.

The KT148A voice chip has two versions: one - wire serial port and button - triggered. With a small SOP8 package, it is flexible and easy to integrate into scenarios such as toys, home appliances, industrial control, and security alarms, and there are already a large number of successful application cases.
