CY7C65632-28LTXCT - USB 2.0 4-Port Hub Controller | Infineon
The Infineon CY7C65632-28LTXCT is a low-power USB 2.0 hub controller from the EZ-USB HX2VL family, supplying up to four downstream ports in a 28-pin QFN package. It is USB 2.0 specification compliant, operates from a single 3.3 V supply, and integrates a single Transaction Translator (TT) for full-/low-speed downstream support, targeted at cost-sensitive hub designs. A USB 2.0 hub controller is a function-specific integrated circuit that aggregates one upstream USB port into multiple downstream USB ports while managing enumeration, power switching, bus enumeration, and transaction translation between the host and connected devices. It belongs to the broader category of USB Interface ICs, within the larger Interface ICs and Integrated Circuits taxonomy. By placing the hub logic and downstream port control on a single die, the HX2VL part eliminates the external TT IC typically required by multi-TT hubs and cuts the BOM for 2- and 4-port hubs. Key features include integrated upstream and downstream USB termination resistors, integrated port-status indicator control (LED drivers), an integrated 24 MHz crystal amplifier, an in-system EEPROM interface for vendor ID / product ID / port-remap customization, and per-port overcurrent detection. The device is configurable via GPIOs to expose 2-port or 4-port topologies and supports both self-powered and bus-powered hub operation. Suspend current consumption is held to a minimum to meet USB 2.0 suspend-current requirements for bus-powered applications. Internally, the HX2VL uses a serial-interface engine for the upstream port and a hub repeater/transaction-translator architecture for the downstream ports, with port-mapping logic driven by the optional external EEPROM. The integrated termination and indicator control reduce PCB area to roughly a 4-layer design with no external PHY, which is the dominant reason designers select this part for compact hub dongles and embedded USB ports. Typical applications include standalone 4-port USB 2.0 hubs for consumer desktops, laptop port replicators, monitors with embedded USB hubs, embedded motherboards, and printer front-panel USB ports. The part is also deployed in industrial USB expansion modules where the GPIO-driven port remapping supports non-standard pin assignments. Designers should keep the 24 MHz crystal or clock source within 5 mm of the XIN/XOUT pins, route the DP/DM differential pairs with 90-ohm differential impedance, and place the upstream port termination near the device pins to preserve USB 2.0 high-speed signal integrity. The optional EEPROM is only required if custom VID/PID or port-disable remapping is needed.

TJA144x - Dual CAN FD Transceiver Family | NXP Semiconductors
The NXP TJA144x is a family of dual high-speed CAN/CAN FD transceiver ICs that provide an interface between a Controller Area Network (CAN) or CAN FD protocol controller and the physical two-wire CAN bus, supporting data rates up to 5 Mbit/s and compliant with ISO 11898-2, SAE J2284 and AEC-Q100 Grade 0. The family is offered in HVSON-14 (3.6x2.0 mm) and HVSON-8 packages, with variants including Basic, Standby, Dual Standby, and Sleep power modes for different power-management strategies in automotive networks. The TJA144x operates from a 4.5V to 40V supply (load-dump tolerant), tolerates -5V to +45V on the bus pins, and integrates dominant-timeout, thermal shutdown, and bus-pin short-circuit protection. A CAN FD transceiver (also called CAN Flexible Data-rate transceiver) is a physical-layer device that converts digital transmit/receive data from a CAN protocol controller into differential voltage levels on the CANH/CANL bus wires. As the boundary between the protocol controller and the bus medium, it provides dominant/recessive arbitration, common-mode rejection, and EMC robustness required in automotive environments. Within the in-vehicle network hierarchy, the CAN transceiver sits below the microcontroller (MCU) and above the wiring harness, forming the physical layer of the OSI seven-layer reference model for CAN. Key features of the TJA144x family include an ultra-low-current Standby mode with remote CAN wake-up detection, very low electromagnetic emission (EME) and high electromagnetic immunity (EMI), excellent ESD protection (±8 kV HBM on bus pins), and pin compatibility with the prior TJA1042/1051 generations for easy retrofit. The HVSON-14 package exposes an exposed thermal pad for low thermal resistance, and the HVSON-8 variant offers a compact footprint for ECU miniaturization. Devices are AEC-Q100 Grade 0 qualified for automotive temperatures from -40 °C to +150 °C. Typical applications include body control modules (BCM), gateway ECUs, ADAS sensor nodes, instrument cluster CAN backbones, electric-vehicle battery-management communication, and any in-vehicle network that requires migration from classical CAN to CAN FD without redesigning the PCB or firmware. The 5 Mbit/s CAN FD capability is essential for high-bandwidth automotive Ethernet-cascade gateways and radar/LiDAR sensor clusters. When designing with the TJA144x, ensure the VCC supply is decoupled with a 100 nF ceramic capacitor close to pin VCC, and that the bus terminations (typically 120 Ω) are present at each end of the CAN bus segment. The VIO pin on HVSON-14 variants allows level-shifting between the 3.3V or 5V MCU and the 5V transceiver logic domain. This page synthesizes distributor pricing, drop-in alternatives within the TJA144x family and from competitor manufacturers, and practical design notes not consolidated on the manufacturer datasheet, giving design engineers a single decision-ready reference for CAN FD physical-layer selection.
TUSB320HAIRWBR - USB Type-C CC Logic, X2QFN-12 | TI
The Texas Instruments TUSB320HAIRWBR is a USB Type-C Configuration Channel (CC) logic and port controller in an industrial-grade (I-temp) active-high enable variant, packaged in a 12-pin X2QFN (RWB) measuring 1.6 mm × 1.6 mm. The device operates from a single 3.3 V supply and supports USB Type-C Specification 1.1 while remaining interoperable with 1.0 systems. It advertises and detects up to 3 A of VBUS current per Type-C current-mode rules and supports DFP (Source), UFP (Sink), and DRP (Dual Role) port roles selected through MODE pins. A USB Type-C Configuration Channel Logic IC is a state-machine controller that sits between a USB Type-C receptacle and the application processor or USB controller. Its job is to negotiate attach/detach events, cable orientation (CC1/CC2 polarity), role (host vs device), and current advertisement (default 500 mA, 1.5 A, or 3 A) through the CC1/CC2 pull-up and pull-down signalling defined by the USB-IF Type-C specification. Higher up the hierarchy it is an Interface IC > USB Interface IC; below it is the CC PHY layer. Key features include: integrated 5.1 kΩ CC pull-up resistors that can be toggled for DRP toggle, hardware MODE pin configuration (no firmware needed), active-high enable (EN) pin for power sequencing, low standby current with a dedicated low-power mode, and HBM ESD protection on CC pins. The X2QFN-12 RWB package keeps the device under 3 mm² footprint, ideal for compact dongles, hubs, and embedded platforms. Typical applications are any 5 V / 3 A USB Type-C ports that need a low-BOM CC controller: travel chargers, USB Type-C dongles, adapters, hubs, docking stations, smartphones, tablets, and notebooks. Because it operates as a standalone state machine with no MCU required, it is well-suited to cost- and board-area-sensitive designs. Design consideration: place the 100 nF decoupling capacitor within 2 mm of VCC and keep the CC traces short, matched, and away from switching nodes to preserve signal integrity. A 0 Ω or ferrite series resistor on VBUS is optional but recommended to limit inrush current at attach.
