Sleep aid voice chip, voice IC with timing function, powerful expansion function WT2003H

Shenzhen Waytronic has developed a single-chip MP3 chip, WT2003H-B007, which integrates seamless loop playback, key scanning, battery power detection, and LED digital tube driver (including indicator light, breathing light, and dot matrix). It can save 60% of MCU resources for customers and save MCU development costs.

WT2003H-B007 uses a high-performance 32-bit processor with a maximum frequency of 120MHz. It has the characteristics of low cost, low power consumption, high reliability, and strong versatility. It can be built-in with 100 seconds, 350 seconds, and 800 seconds of voice capacity, built-in 8 ohm 0.5W amplifier circuit, uses standard UART communication mode, supports DMA and flow control, default baud rate is 9600, audio sampling supports 8kbps~320kbps with beautiful sound, supports power supply voltage detection, and supports 3-level voltage alarm output. In addition, WT2003H-B007 has a timing function (0-255 minutes). Such a powerful expansion function can save engineers more than 10 days of development cycle;

Chip/MCU Solution

The existing SOP16, SSOP24, and QFN32 packages can customize more extended functional applications for engineers, such as: LED display driver, key scanning, ultrasonic atomization, pressure sensor detection, ADC detection, infrared sensing, ultrasonic ranging, temperature detection, etc., which can save engineers development cycles and difficulties;
