jmicron/JMB311 copyright ? 2011 jmicron inc. all rights reserved. product brief page 1 2011/05/30 JMB311 usb2.0 uvc webcam controller overview JMB311 is a low power usb2.0 pc/nb camera controlle r. it incorporates a high speed usb2.0 transceiver, a cmos sensor interface, a spi serial interface and a low-power 8051 cpu. JMB311 is fully compliant with usb video class (uvc ) 1.1. with the flexible and programmable cmos sensor interface, it can support a variety of sensor sources, like omnivision, micron/aptina and others, up to uxga(1600*1200). JMB311 also provides real-time vga-size preview mod e up to 30 frames per second on different resolutions. in addition, a built-in 5v/3.3v voltag e regulator could reduce the system bom cost. overall 3.3v single power, 1.8v core power from internal re gulator. built-in regulator from 5v to 3.3v lower power consumption (operation < 55ma, standby < 45ma & suspend < 300ua) built-in dp8051 (16kb code sram for easy update) built-in jtag interface for easy debug gpio for led indicator, shutter button, module flip detection, sensor power-down control, sensor reset, i2c(scl & sda) and spi i/f (cs, sclk, si & so). built-in watchdog timer 46-pin lqfn (4.5mm*6.5mm) sensor interface support cmos sensor (omnivision & micron) support yuy2 (8 bit), rgb(565) and rgb bayer patter n (8 bit). down-sampling frames for flow control video streaming up to 30 fps@vga, 9fps@sxga and 6fp s@uxga at high-speed operation vga preview mode 30fps for sxga & uxga. output max.60mhz sensor clock. support clock divider (%2, %4,) for 30fps series(3 0, 15, 7.5fps) and 25fps series(25,12.5, 6.25). usb usb 2.0 usb video class 1.1 compliant remote wake-up support 3 endpoints: control *1, isochronous*1/ bul k*1 and interrupt*1 www.datasheet.co.kr datasheet pdf - http://www..net/
