Technology CorporationThe SD8233B is a Touch Screen Controller IC from SHOUDING Technology Corporation. It is a SOT23-6 RoHS part, a small surface-mount package. It can detect and measure the position and the area of single- or multi-touch, also it can recognize the gesture and transmission. Its features include a resistance-based touch screen, a noise-protection filter, and a high-sensitivity capacitive touch screen with up to 100 cm2 of active area. Its maximum supply voltage is 3.6V and it has five touch keys and one power-on key. This IC can operate in both single- and multi-touch, gesture, and coordinate applications. It supports various communication protocols, such as I2C, SPI, and RS-232. Data is collected through an analog voltage measurement. This IC is compatible with various operating systems, such as Windows, Android, and iOS.
