The SX8650ICSTRT is a low-power, four-channel resistive touch screen controller manufactured by Semtech. It features a 12-bit analog-to-digital converter for high-precision coordinate and contact pressure measurement. The device supports I2C interface communication at 400 kHz Fast Mode and operates within a supply voltage range of 1.65V to 3.7V. Designed for compact applications, it offers enhanced electrostatic discharge (ESD) protection rated at ±15kV. The component is optimized for minimal power consumption and small footprint size.
The SX8650ICSTRT belongs to the SX8650 series of touch screen controllers from Semtech. It serves as an entry-level solution in this platform, focusing on balancing power efficiency, physical size, and robustness against electrostatic discharge for consumer electronics requiring resistive touch input.
The SX8656IWLTRT is a related resistive touch controller from Semtech offering similar functionality but may differ in package type and specific electrical characteristics. Verification of pin compatibility and interface requirements is necessary when substituting.
