Product details
Overview
TUSB8044ARGCR from Texas Instruments is a four-port USB 3.2 x1 Gen1 (5 Gbps) hub IC with integrated USB 2.0 Billboard 1.21 functionality, MTT architecture, per-port/ganged power switching, and I2C-based HID-to-I2C bridge for configuration and control - deployed in docking stations and monitors requiring simultaneous SuperSpeed and high-speed downstream connectivity.
For engineers reviewing the TUSB8044ARGCR datasheet, TUSB8044ARGCR pinout, TUSB8044ARGCR application, or TUSB8044ARGCR equivalent, key selection criteria include USB 3.2 x1 Gen1 hub topology, 64-pin VQFN (RGC) package compatibility, battery charging mode support (CDP/DCP/ACP), Billboard 1.21 compliance, and I2C/SMBus programmability of VID/PID and port configurations.
Technical Context
The TUSB8044ARGCR implements a Multi-Transaction Translator (MTT) hub architecture with four independent transaction translators and two asynchronous endpoint buffers per translator, enabling concurrent high-speed USB 2.0 device handling across all downstream ports. It supports dynamic upstream link negotiation - disabling SuperSpeed when upstream connects only to USB 2.0 hosts.
Its integrated USB 2.0 Billboard device resides on the highest-numbered downstream port and reports Alternate Mode status per USB Billboard Device Class Specification 1.21. The internal HID-to-I2C interface operates at speeds matching the upstream port (high-speed or full-speed), enabling real-time EEPROM and register access via USB 2.0 without external controllers.

| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| USB7252-64 | 8-port USB 3.2 Gen1 hub with PCIe upstream interface; no integrated Billboard; requires external configuration EEPROM | Targeted at PCIe-based host systems (e.g., servers, embedded x86); lacks native USB upstream and Billboard functionality | Select when upstream connectivity is PCIe-based and Billboard is handled separately |
| TUSB8041ARGCT | Single-chip 4-port USB 3.2 Gen1 hub in same RGC package; identical Billboard, HID-to-I2C, and charging features; differs only in temperature grade (industrial –40°C to 85°C) | Same functional scope but qualified for extended temperature environments; pinout and firmware compatible | Select for industrial deployments requiring wider ambient operating range |

FAQ
What is the primary function of the TUSB8044ARGCR?
The TUSB8044ARGCR is a four-port USB 3.2 x1 Gen1 hub IC that manages simultaneous SuperSpeed (5 Gbps), high-speed (480 Mbps), and full-speed (12 Mbps) USB traffic between an upstream host and up to four downstream devices. It integrates a USB 2.0 Billboard 1.21 device and an HID-to-I2C bridge, enabling status reporting and peripheral control without external microcontrollers. Its role in system design is to consolidate USB connectivity while maintaining USB-IF compliance and reducing BOM complexity.
Does the TUSB8044ARGCR support USB Battery Charging standards?
Yes, the TUSB8044ARGCR supports multiple USB Battery Charging standards: CDP (Charging Downstream Port) when the upstream port is connected; DCP (Dedicated Charging Port) and ACP (Accessory Charging Port) modes when upstream is unconnected; and compliance with Chinese Telecommunications Industry Standard YD/T 1591-2009 and Samsung Galaxy charging protocols. These modes are configurable via hardware strapping (PWRCTLx/BATENx pins) or register control, allowing flexible implementation in wall adapters, docks, and monitors.
How is the Billboard functionality implemented in the TUSB8044ARGCR?
The TUSB8044ARGCR implements Billboard functionality per USB Device Class Definition for Billboard Devices Version 1.21. Its integrated Billboard device resides on the highest-numbered downstream port (Port 4) of the internal USB 2.0 hub and communicates Alternate Mode status (e.g., DisplayPort Alt Mode) directly to the host OS. Configuration of bmConfigured bits is controlled by BBbmConfigured0/BBbmConfigured1 pins or SMBus registers, ensuring accurate mode reporting without firmware intervention.
Can the TUSB8044ARGCR be configured using I2C after deployment?
Yes, the TUSB8044ARGCR supports live I2C/SMBus configuration post-deployment via its SCL/SMBCLK and SDA/SMBDAT pins. This allows runtime read/write access to internal registers, EEPROM, and I2C peripherals through the integrated HID-to-I2C bridge. Supported operations include VID/PID modification, port enable/disable, battery charging mode selection, and custom string updates - all executed over the USB 2.0 upstream connection without requiring physical rework or reflashing.
What package and thermal characteristics does the TUSB8044ARGCR have?
The TUSB8044ARGCR is housed in a 64-pin VQFN (RGC) package measuring 9.0 mm × 9.0 mm with an exposed thermal pad. Its thermal metrics include RθJA = 26°C/W (junction-to-ambient), RθJB = 5.3°C/W (junction-to-board), and RθJC(bot) = 1.0°C/W (junction-to-case bottom), enabling efficient heat dissipation in compact, fanless applications. It operates across 0°C to 70°C ambient temperature and supports standard reflow soldering profiles per JEDEC J-STD-020.
