1. Overview of SN9C5259AFG
The SN9C5259AFG is a USB 2.0 High speed (HS) compatible camera controller. Advanced power consumption design keeps the device in suspended, standby or running state Power consumption is extremely low. The low thermal design makes the operating temperature of the module in the platform always within a reasonable range. SN9C5259AFG fully conforms to the USB video class. the operating systems include Microsoft systems (Windows XP, Windows Vista, Windows 7, and Windows 8), Apple systems, and Linux-based systems. The system (e.g., Ubuntu.Android... Etc.).
SN9C5259AFG supports 10-bit parallel sensor interface, resolution up to 5MP@15fps; Or support access to 4 LANE MIPI interface sensors,Maximum support 8M@15FPS. With the I2S interface, you can extend audio compatibility or access a digital microphone. A new generation of image signal processors Better visual experience. The high-performance dynamic JPEG compression engine offers different compression ratios to meet bandwidth requirements. Through integrated sensor interface and color Color processing engine that can support most available CMOS sensors. Controlled by an embedded microcontroller with built-in 3 (AE/AWB/AF) statistics. The structure is flexible and consists of Mask ROM, internal RAM and external serial flash memory, which can be used to store custom code and parameters. Through highly integrated quantiles.
The architecture and development kit provided by Songhan make it easy for third parties to implement custom functions.
