Detailed Product Description
UART/I2C/SPI Interface
In addition to the USB and SD/MMC that the interface for big data transferring, USB OTG Controller also have interfaces that use for communicating with other controller such as Universal Asynchronous Receiver/Transmitter (UART), Inter IC interface (I2C) and Serial peripheral interface (SPI).
Like the information security solutions, they integrate fingerprint sensor, secure chip embedded secure element or NFC sensor, etc. They are all communicated with UART, I2C and SPI interfaces. That's why 's solutions can be integrated with variety functions of controller. As long as both sides have the same communication interfaces and set the protocol, you can create more innovative solutions.
