Microchip offers a comprehensive product portfolio of automotive USB, USB bridge controllers, USB clock re-timers and re-drivers, covering specifications from USB 2.0 High-Speed to USB 3.2 SuperSpeed. Designed for applications such as in-vehicle infotainment, multi-port expansion in the cockpit, long-distance signal transmission and cross-interface conversion, all products comply with stringent reliability standards and are tailored to the development requirements of automotive and industrial embedded systems.

I. In-Vehicle USB Products

Microchip’s in-vehicle USB series is AEC-Q100 certified, suitable for the wide operating temperature range typical of automotive applications. It has been specifically optimised for complex in-vehicle electromagnetic environments, long cable runs and multi-device connectivity, making it a core component for in-dash infotainment systems, rear-seat multimedia, Type-C charging and data ports, and smartphone connectivity solutions.

The product range includes USB hub controllers, USB power management solutions and USB signal switching devices. It supports both USB 2.0 High-Speed (480 Mbps) and USB 3.2 Gen 1 (5 Gbps) speed classes, and is natively compatible with CarPlay, Android Auto and in-vehicle connectivity protocols. It also supports the BC1.2 charging specification and USB PD power negotiation, enabling both high-speed data transfer and high-power device charging simultaneously.

The products incorporate patented FlexConnect technology, which supports dynamic role swapping between upstream host ports and downstream device ports, enabling seamless host switching without the need for additional external circuitry. Coupled with MultiTRAK multi-transaction converter technology—where each port features an independent transaction converter—full-speed data throughput remains stable even during concurrent multi-device connections, preventing bandwidth contention and stuttering. The device incorporates a 32-bit embedded MCU, enabling port configuration, power supply control, firmware management and in-system update logic to be handled internally, thereby reducing the number of peripheral components and lowering the overall BOM cost of the system.

Typical applications include in-vehicle central control units, armrest and rear-seat USB splitter boxes, in-vehicle media adapters, and in-vehicle card reader modules. The device supports flexible port configuration, port deactivation and remapping, enabling automotive manufacturers to adapt to different vehicle configurations on a single hardware platform. A comprehensive suite of reference designs, evaluation boards and MicroCHECK design verification services is provided to assist engineers in identifying signal integrity and compliance risks at an early stage.

II. USB Bridge Controllers

USB bridge controllers act as hubs for heterogeneous interface conversion, enabling data exchange between the USB bus and other low-speed peripheral buses. They are widely used in embedded systems, in-vehicle control boards, peripheral expansion and firmware upgrade channels.

These devices integrate a USB device controller, the PHY layer and multiple sets of hardware peripheral interfaces, enabling signal conversion from USB to GPIO, I²C, SPI, UART, I²S and other protocols. Some models also incorporate hub functionality, allowing them to expand USB ports whilst outputting multiple control signals; a single chip thus handles both USB data distribution and system I/O bridging.

The bridge controller supports OTG mode, allowing flexible switching between host and device roles. Its low-power architecture is suited to standby and sleep scenarios; in automotive systems, it is used for debugging body peripherals, in-circuit programming of modules, audio signal relaying and sensor data uploading. The chip supports OTP (One-Time Programmable) memory, enabling port parameters, power supply strategies and role logic to be fixed at the factory, eliminating the need for additional configuration circuits during production.

Some smart hub-type bridging devices integrate PD protocol processing capabilities; the on-chip MCU directly executes PD contract negotiation and, in conjunction with external power switches, manages power delivery via the Type-C port. This simplifies the development of fast-charging port solutions and is suitable for automotive, industrial gateway and portable docking station designs.

III. USB Clock Reclocker / Redriver

USB clock re-timers/re-drivers, also known as Reclockers/Redrivers, include representative models such as the automotive-grade EQCO510 and the industrial-grade EQCO5X31. Designed for USB 3.2 Gen 1 5 Gbps SuperSpeed signal chains, they address issues such as signal attenuation, jitter accumulation and eye diagram degradation caused by long cables and lengthy PCB traces, serving as specialised devices for the relaying and extension of high-speed USB signals.

The device integrates an adaptive equaliser, a bit-level clock and data recovery (CDR) module, and an output driver unit, all operating bidirectionally simultaneously. The receiver utilises EyeOpen adaptive compensation technology to automatically compensate for high-frequency cable loss, with a compensation range of 0 to 20 dB in 1 dB steps; the CDR clock re-timing module re-synchronises the data clock, eliminating jitter accumulated at each stage of the link, thereby ensuring that signal timing once again complies with the USB 3.2 specification; the re-drive unit re-transmits the shaped and re-timed clean signal back to the cable or PCB traces, enhancing drive capability.

The EQCO510 is an automotive-grade device, compliant with AEC-Q100 Grade 2, with an operating temperature range of –40 °C to 105 °C. It requires no external reference crystal oscillator, and its reference-clock-free architecture further simplifies the peripheral circuitry. It features a built-in MarginLink signal integrity detection function, supporting real-time monitoring of link signal quality, which facilitates production line testing and fault diagnosis.

In automotive applications, the transmission distance of standard USB 3.2 cables is limited; this device can extend a pure USB 3.2 link to 15 metres and, when used with hybrid USB 2.0 cables, up to 5 metres. It enables an upgrade to 5 Gbps high-speed connectivity without altering the installation positions of the vehicle’s original centre console or adapter box. The device is transparent to all USB 3.2 signalling, including LFPS (Low-Power Signalling) and electrical idle states, and does not interfere with the Type-C PD negotiation process. It also supports spread-spectrum modulation to reduce EMI (electromagnetic interference), whilst the idle link enters an ultra-low-power sleep mode. It is suitable for in-vehicle media boxes, long-distance Type-C cabling within the passenger compartment, high-speed USB extension for industrial cameras, and signal relaying for test and measurement equipment.
