Nowadays, with the development of technology, microwave ovens are also developing towards intelligent interactive experience. However, many manufacturers need to spend a lot of time and energy in the process of designing interactive experience. Microwave ovens on the market usually have an LED display . This is the interactive method of visual communication with the user . The user sets the heating time, which will be displayed on the LED digital tube , telling the user the heating time and the remaining time of the countdown;

Nowadays, in order to improve the interactive experience of the product, many manufacturers will join The voice function requires an additional voice chip + power amplifier chip on the PCB board, which takes up space. The traditional solution requires MUC + LED display driver chip + voice chip + power amplifier chip. This series of solutions not only requires BOM The overall cost is high, and so many chips also occupy a lot of space on the PCB, increasing the complexity of the circuit.

Shenzhen Weichuangzhiyin has developed a single chip to achieve this series of solutions: 4-digit LED display driver + voice playback function. The chip has a built-in power amplifier circuit that can directly drive 8R0.5W speakers and buzzers. DAC amplifier can be added.

WT588F02KD-24SS digital tube driver chip solution

WT588F02KD-24SS (SSOP24 package) is a driver control with keyboard scanning interface LED (light emitting diode display (4 bit)). It is a device with voice broadcast function + LED segment code display Driver dedicated chip. The chip can accommodate up to 200 seconds of voice content. The chip also integrates MCU scalable functions, LED digital tube driver interface, keyboard scanning interface, etc.

WT588F02KD-24SS can be well applied to the display screen driving voice broadcast circuit of small household appliances such as induction cookers and microwave ovens. It has a built-in PWM (8R0.5W power amplifier circuit) that can directly drive the speaker output, and can be added with an DAC audio amplifier.

WT588F02KD-24SS Functional Features

(1) uses the standard serial port , baud rate: 9600 (N, 8, 1, 1);

(2) keyboard scanning (8x2bit), with enhanced anti-interference key recognition circuit, The anti-interference performance of the keys is enhanced;

(3) is equipped with key wake-up, active scanning function, and key return;

(4) customers can replace the internal voice content of the chip online through the supporting downloader;

(5) can support LED ( The display mode of the light-emitting diode display (4 digits) ------- 8 segments Adjustment, using 1K frequency;

(7) can support independent dimming of 32 light-emitting diodes of four-digit digital tubes at the same time
