If you're working on smart appliances or industrial control devices, having a reliable and fast MCU with solid touch capabilities is key. The AXTEK AX8F83XX series is based on an enhanced 1T tiny 8051 core — fully compatible with the classic 8051 but runs up to 10 times faster.

What’s Inside?

This chip comes with 32KB Flash, 1.5KB SRAM, and supports up to 26 touch keys — great for touch sliders and buttons. It also has a precise 12-bit ADC and multiple PWM channels for motor and LED control.

It supports common communication protocols — UART, I2C, SPI — so it fits well in various system designs. The LED driver supports smooth dimming and matrix display, ideal for lighting products.

Perfect for Touch Slider Applications

AX8F83XX handles up to 26 capacitive touch keys with waterproof design that works even through plastic or glass panels. This makes it great for electric shavers, smart lighting, and many other consumer or industrial devices.

The slider supports smooth speed adjustment and recognizes forward/reverse swipes, combined with high-precision amplifiers and PWM outputs to control motors or LEDs effectively.

Reliable and Resistant

Built-in power-on and power-off reset, low voltage detection with 8 levels, plus a watchdog timer to avoid system freezes make this MCU very stable. 

It can wake up from low-power modes quickly with its wake-up timer.

It also passes tough interference tests like EFT ±4KV and ESD ±8KV, so it works reliably in noisy environments.

Flexible Packaging and Wide Application

Available in multiple package types including SOP28, TSSOP28, and QFN28, the AX8F83XX series offers design flexibility for engineers. It has been widely adopted in:

• Electric shaver touch slider controls

• Smart home lighting with stepless dimming

• Intelligent switches and control panels

• Wireless communication devices and IoT terminals

• Industrial automation and control equipment

Summary

The AXTEK AX8F83XX MCU gives you a powerful, low-power, and highly integrated solution for touch sliders and embedded control. If you want a stable, fast chip with plenty of features for smart appliances or industrial controls, this is a solid choice.
