The SL8022KS with SOP-8 Touch Screen Controllers ROHS is a low power, low voltage, single-chip application-specific integrated circuit (ASIC) designed and manufactured by SLKORMICRO. It is based on a programmable 8-bit microcontroller and has proprietary dual voltage range operating from 1.65 V to 3.6 V.The SL8022KS is specialized for touch screen and light industry applications. It features a fast boot-up time and provides functions including capacitive touch sensing, temperature compensation, and LCD refresh. Additionally, the device includes a built-in low-noise buck-boost converter that makes it suitable for applications with various power supply fluctuation conditions.The SL8022KS has a wide supply voltage range from 1.8 V to 3.6 V, and can operate at peaks up to 4.75 V. It also has an I2C serial interface and 2 independent communication channels to support both slow and fast communication rates. The device also supports UART (Universal Asynchronous Receiver/Transmitter) data transmission for communication with a wide variety of external devices.
