JMB310 USB2.0 UVC WebCam Controller
JMB310 is a low power USB2.0 PC/NB camera controller. It incorporates a high speed USB2.0
transceiver, a CMOS sensor interface, a SPI serial interface and low-power 8051 CPU.
JMB310 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 such as Omnivision, Micron/Aptina,
Samsung and others, up to UXGA (1600 x 1200). JMB310 also provides real-time VGA-size preview mode
up to 30 frames per second on different resolutions. In addition, a built-in 5V/3.3V voltage regulator could
reduce the system BOM cost.
3.3V single power, 1.8V core power from internal regulator.
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 debugging.
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 watch dog timer
46-pin LQFN (4.5mm*6.5mm)
Sensor Interface
Support YUY2 (8 bit), RGB (565) and RGB Bayer patter (8 bit)
Down-sampling frames for flow control
Video streaming up to 30fps@VGA, 9fps@SXGA ad 6fps@UXGA at high-speed operation
VGA preview mode 30fps for SXGA & UXGA
Output maximum 60MHz sensor clock
Support clock divider (1/2, 1/4, …) for 30 fps series (30, 15, .5.. fps) and 25 fps series (25, 12.5,
USB 2.0 interface
USB Video Class 1.1 compliant
Remote wake-up
Support 3 Endpoints: Control x 1, Isochronous x 1 and Interrupt x 1
