The built-in extreme low-power transceiver provides the superior compatibility with various USB host and the best quality for image applications. It is fully compliant with USB Video. With the integrated sensor interface and color processing engine, it can support most available VGA CMOS ISP sensors. The high performance Motion-JPEG compression engine makes variant compression ratio to satisfy bandwidth requirement which output MJPG data format and reach 30fps or higher at VGA on both HS and FS. SN9C258C is controlled by the embedded micro-controller, and the statistics for Auto Exposure and Auto White Balance are built-in. The flexible architecture is consisted of mask ROM, internal RAM and external serial-flash which can store the customized codes and parameters. It’s also possible to store all the program code in the external flash memory for special design purpose. With the highly-integrated firmware architecture and the developing kit provided by SONiX, it’s easy for 3rd party to fulfill any specific feature. 本資料為松翰科技股份有限公司專有之財產，未經書面同意不准透露、使用，亦不准複印或轉變成任何其他形式 使用 The information contained herein is the exclusive property of SONIX and shall not be distributed, reproduced or disclosed in whole or no in part without prior written permission of SONIX. -3- 松翰科技股份有限公司 SONiX TECHNOLOGY CO., LTD 2 Features 2.1 System 3.3V single power supply, 1.8V Core (generated by internal regulator) and 3.3V I/O Extreme low power consumption, < 43mA when standby and < 400uA when suspend (Power consumption of sensor is not included) Built-in PLL for internal clock generation with input crystal frequency of 12MHz Using external serial flash to store customized code and data No external RAM needed 2.2 USB Controller USB 2.0 high-speed and full-speed compatible USB Video Class 1.1 compliant USB2.0 HS/FS auto sense and switch USB FS mode and USB disconnection are programmable 4 endpoints: CONTROL pipe, Interrupt IN and 2 Isochronous-IN (Video Out and Audio Out) 6 alternate settings for Video Streaming Interface 2.3 Sensor Interface Support VGA CMOS ISP sensor Support YUY2 and RAW (Bayer-Pattern) image data format from sensor Output clock: Programmable output clock on variant options, 48/30/28/27/26/25/24Mhz Input clock: Maximum acceptable Pixel Clock is 30Mhz Support industrial standard 2-wire serial interface for sensor control 2.4 Image Processing (Bayer) Input windowing Static defect-pixel correction (127 dots, stored in serial flash) On-the fly defect-pixel concealment Lens shading compensation for R/G/B channel Individual digital color gain control for R/Gb/Gr/B channel Pixel offset (optical black) compensation for R/Gb/Gr/B channel Programmable gamma table for R/G/B channel Configurable noise reduction Configurable edge enhancement 本資料為松翰科技股份有限公司專有之財產，未經書面同意不准透露、使用，亦不准複印或轉變成任何其他形式 使用 The information contained herein is the exclusive property of SONIX and shall not be distributed, reproduced or disclosed in whole or no in part without prior written permission of SONIX. -4- 松翰科技股份有限公司 SONiX TECHNOLOGY CO., LTD 2.5 Color processing AE window statistics AWB window statistics Individual digital color gain control for Y/Cb/Cr channel Programmable color correction matrix (RGB to YUV) Programmable gamma table for Y channel Configurable windowing function after processed image 2.6 Scaling Engine 1/2, 1/4 smooth scaling on Y/Cb/Cr 3/5, 4/5 bilinear scaling on Y/Cb/Cr 2.7 JPEG Encoder JPEG YUV422 baseline format Built-in JPEG encoder support USB Video Class MJPEG payload 128 bytes quantization tables for Y and C provide programmable compression ratio The JPEG encoder is capable of compressing VGA video at 45fps. 2.8 Video / Still Image Output video / still image format: USB Video Class Uncompressed YUY2 payload (16bits/pixel) USB Video Class MJPG payload Still Image capturing support UVC still image capture method 0/1/2 2.9 Frame rate Frame rate considering USB bandwidth limitation Full-speed mode Output format VGA CIF QVGA QCIF QQVGA YUY2 1.5fps 4.5fps 6.5fps 19.5fps 26fps MJPEG 30fps 30fps 30fps 30fps 30fps High-speed mode Output format VGA CIF QVGA QCIF QQVGA YUY2 30fps 30fps 60fps 60fps 60fps MJPEG 45fps 60fps 60fps 60fps 60fps Frame rate considering sensor characteristic 本資料為松翰科技股份有限公司專有之財產，未經書面同意不准透露、使用，亦不准複印或轉變成任何其他形式 使用 The information contained herein is the exclusive property of SONIX and shall not be distributed, reproduced or disclosed in whole or no in part without prior written permission of SONIX. -5- 松翰科技股份有限公司 SONiX TECHNOLOGY CO., LTD The maximum frame rate is limited by how many fps that sensor can output under acceptable maximum pixel clock 2.10 Audio Build-In one channel Cyclic ADC Programmable audio sampling frequency: 8, 16, 24 and 48 kHz Audio bit resolution is 16 bits/stereo 2.11 GPIO Maximum 3 GPIO available GPIO action is able to link to the built-in HID class 2.12 Micro Controller and USB Device Features Built-in 8032 micro controller with 3K bytes data memory, and maximum CPU clock rate is 24MHz Total 64K bytes code memory include 48K bytes mask ROM and 16K bytes SRAM Load extended 16KB F/W from external serial flash.
