TUSB2036VFR Descripción general
A USB hub controller is an interface IC that expands a single upstream USB port into multiple downstream ports, handling enumeration, power management, and port status reporting per the USB specification. Within the system hierarchy, it sits under USB interface ICs -> connectivity controllers -> semiconductors, and is a core building block in any product that must offer multiple USB device connections.
Key features include compliance with the USB 2.0 specification at full-speed (12 Mbps), up to three programmable downstream ports, fully-compliant integrated transceivers on all upstream and downstream ports, and an optional serial EEPROM interface for storing vendor-specific configuration data such as VID/PID.
Architecturally, the TUSB2036 is implemented as a 3.3V CMOS digital state machine (ASIC) rather than a microcontroller, which means no firmware development, programming, or flash memory is required - the device is fully functional as soldered. A dedicated DP0PUR pin (pull-up resistor disable) simplifies implementation of onboard bus-power/self-power dynamic-switching circuitry, reducing external BOM cost in bus-powered designs.
Typical applications include standalone USB hubs, monitors and docking stations with USB ports, printers and multifunction peripherals, set-top boxes, and industrial equipment requiring multiple USB device ports from a single host connection.
A key design consideration is power configuration: in bus-powered mode all downstream ports must draw within the USB budget of 500 mA total, whereas self-powered designs use the DP0PUR-based switching scheme and require proper VBUS sensing on downstream ports. The optional serial EEPROM allows custom VID/PID programming without firmware.

Aplicaciones típicas
TUSB2036VFR es adecuado para 6 aplicacións: Standalone USB Hubs, Monitors and Docking Stations, Printers and Multifunction Peripherals, Industrial Equipment with USB Ports, Set-Top Boxes and Consumer Electronics, Bus-Powered Peripheral Designs.
Standalone USB Hubs
The TUSB2036VFR is the core controller of a standalone USB hub, expanding one upstream port into two or three downstream full-speed ports. Its state-machine architecture removes any firmware development or microcode storage, which shortens time-to-market for hub products. Integrated transceivers on all ports eliminate external PHY chips, cutting BOM count. In bus-powered designs, the DP0PUR pin enables compliant bus/self-power dynamic switching, keeping total downstream current within the USB budget of 500 mA. The optional serial EEPROM lets OEMs program custom VID/PID values for branded hub products without any code maintenance.
Recomendado
Monitors and Docking Stations
Monitors and docking stations commonly expose several USB ports to the host; the TUSB2036VFR provides up to three downstream full-speed ports from a single upstream connection. Because it requires no firmware, the USB section of the monitor mainboard needs no programming station in production, reducing manufacturing complexity. The 3.3V CMOS design draws low power, which matters in monitors where standby power limits are strict. Its LQFP-32 (7x7 mm) footprint fits densely populated mainboards, and the serial EEPROM option allows the monitor OEM to brand the hub enumeration with a custom VID/PID string.
Recomendado
Printers and Multifunction Peripherals
Printers and MFP devices integrate USB hub circuitry to offer host and device ports simultaneously. The TUSB2036VFR adds two or three downstream full-speed ports with full USB 2.0 compliance at 12 Mbps, sufficient for card readers, control panels, and low-speed peripherals inside the printer. Its digital state machine guarantees deterministic enumeration behavior without firmware bugs or update cycles. The DP0PUR pin simplifies bus-power/self-power mode switching when the printer transitions from standby (bus-powered behavior) to active operation, and integrated transceivers reduce external components on the formatter board.
Recomendado
Industrial Equipment with USB Ports
Industrial controllers, data loggers, and test instruments frequently need several USB ports for configuration sticks, storage, and peripherals. The TUSB2036VFR supplies up to three full-speed ports from one upstream link, and its firmware-free operation avoids the qualification burden of embedded code in regulated industrial environments. The 3.3V CMOS ASIC keeps power dissipation low inside sealed enclosures with passive cooling. For industrial deployments with wider ambient temperature requirements, the TUSB2046BIVFR variant in the same LQFP-32 package family offers an extended temperature grade option worth evaluating.
Recomendado
Set-Top Boxes and Consumer Electronics
Set-top boxes, media players, and game accessories use the TUSB2036VFR to expand a single host port into multiple ports for remotes, storage, and input devices. Full-speed 12 Mbps operation suits HID peripherals and low-rate storage, and the hub presents no firmware-update liability across the product lifecycle - an important consideration for consumer goods that cannot be serviced. The small 7x7 mm LQFP-32 package fits cost-driven consumer mainboards, and the EEPROM interface permits per-customer VID/PID customization demanded by brand-name OEM channels, all at a low controller cost.
Recomendado
Bus-Powered Peripheral Designs
Designs that must operate entirely from the upstream VBUS 5V rail use the TUSB2036VFR's DP0PUR pin to implement dynamic bus-power/self-power switching per USB specification requirements. The dedicated pull-up-disable function, introduced specifically on the TUSB2036, replaces a discrete switching circuit, which TI states reduces total board cost while adding product value. The 3.3V rail is derived locally with an LDO, and downstream port power is managed with current-limited switches so the aggregate load stays within the 500 mA bus-powered budget. Integrated transceivers and no firmware keep the BOM minimal for cost-sensitive peripherals.

Notas de diseño
In bus-powered configurations, all downstream ports plus the TUSB2036VFR itself must operate within the 500 mA allocated by the upstream port. Budget the hub controller quiescent current (per the TI datasheet) plus each peripheral, and use current-limited power switches such as the TPS2051B on each downstream VBUS. For dynamic bus/self-power designs, use the DP0PUR pin to disable the DP0 pull-up when switching to self-powered mode, maintaining USB compliance for VBUS current reporting.
Place the 3.3V decoupling capacitor (typically 0.1 uF ceramic) within 2 mm of each supply pin of the LQFP-32, with a bulk 10 uF capacitor nearby. Route the USB D+/D- pairs as 90-ohm differential pairs with length matching within 1-2 mm; keep them away from clocks and switching-regulator nodes. The optional serial EEPROM should sit close to the SCL/SDA pins with pull-ups per the EEPROM datasheet.
Do not assume high-speed (480 Mbps) operation - this hub is full-speed 12 Mbps only, which is a frequent selection mistake. Also verify that the TUSB2046B alternatives are truly pin-compatible before PCB reuse, since the four-port die may reassign some pins relative to the three-port TUSB2036. Finally, confirm the operating temperature range in the current TI datasheet revision rather than relying on older USB 1.1-era documentation.
