Overview
JMicron/JMB311 JMB311 USB2.
0 UVC WebCam Controller Overview JMB311 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 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 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.
Overall 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 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).
