VL107是一个高度集成的单芯片显示端口alt模式和USB电源交付3.0控制器，具有安全的FW更新控制台设计的USB- c多功能端口通过充电功能。VL107集成了USB-C充电UFP，可实现DP变换模式视频输出功能，检测到外接电源后，可同时对连接的PD主机充电。集成的第二个USB-C DRP既可以连接USB-C电源适配器为PD主机充电，也可以连接USB-C设备访问数据传输。集成了D+/D-充电ePHY，支持使用D+/D-引脚进行电源协议握手，然后转换为USB PD协议的充电器。VL107的设备策略管理器可以协商其DFP和UFP之间的功率规则，然后使功率充电通过。支持电池无电模式下对主机充电，支持PD3.0快速角色切换。DP AUX通道内置USB-C SBU1/SBU2交换机，满足DP高模AUX通道电阻要求。内置USB公告牌设备功能，满足“VESA DP Alt-Mode on USB Type-C”规范。VL107还支持智能自动待机，当连接接口处于空闲状态时，自动进入深度省电模式。
为了避免FW的恶意攻击，VL107的非对称安全升级控制台内置了ECDSA256、SHA256和随机数生成器，通过ECDSA Verify对FW进行安全升级。它的安全FW升级控制台不仅可以安全升级FW本身的VL107，还可以通过I2C接口和SPI flash接口安全升级多个第三方控制器。FW图像做ECDSA验证是在VL107的备用SPI flash上进行的。内置微调RC振荡器，线性稳压器，Vbus电压和电流检测器，VL107可以完美的工作在Vbus电源和监测异常的功率行为。多达13个GPIO引脚可用于特定的应用用途。SPI接口支持外接SPI flash或与VLI Hub控制器共享SPI flash进行固件升级。VL107可在qfn48l (6x6x0.85 mm)。
VL107 is a highly integrated single chip DisplayPort Alt-mode and USB Power Delivery 3.0 controller with secure FW update console designed for USB-C multi-function docks with charge through function. Integrated USB-C charging UFP, VL107 can perform DP alt-mode video output functionality and simultaneously charging connected PD host once external power source is detected. Integrated second USB-C DRP can either connect to USB-C power adapter to charge PD host or connect to USB-C devices to access data transfer. A D+/D- charging ePHY is integrated to support chargers using D+/D- pins to do power protocol handshake and then converted to USB PD protocol. VL107’s Device Policy Manager could negotiate power rules between its DFP and UFP then enable power charge through. Charging a host under dead battery mode and PD3.0 fast role swap are supported. DP AUX channel to USB-C SBU1/SBU2 switch is built-in to meet DP Alt-mode AUX channel resistance requirement. USB Billboard device function is built-in to meet “VESA DP Alt-Mode on USB Type-C” spec. VL107 also support smart auto-standby that automatically entering deep power saving mode when connected interface is in idle state.
To avoid malicious FW attacks, VL107’s asymmetric secure FW update console has built-in ECDSA256, SHA256, and Random Number Generator to perform secured FW update through ECDSA Verify. Its secure FW update console not only can secured FW update VL107 itself, but also can secured FW update multiple 3rd-party controllers through I2C interface and SPI flash interface. FW image to do ECDSA Verify is performed on VL107’s spare are of SPI flash. Built-in trimmed RC oscillator, linear voltage regulators, Vbus voltage and current detectors, VL107 can work perfectly by Vbus power and monitor abnormal power behavior. Up to 13 GPIO pins are available for specific application usage. The SPI interface can support external SPI flash or sharing SPI flash with VLI Hub controller for firmware upgrade. VL107 is available in QFN 48L (6x6x0.85 mm).
