Product details
Overview
TUSB8043ARGCR from Texas Instruments is a four-port USB 3.2 x1 Gen1 (5 Gbps) hub IC with integrated USB 2.0 MTT architecture, supporting simultaneous SuperSpeed and high-speed upstream connectivity and per-port power switching, over-current detection, and battery charging modes (CDP/DCP/ACP/Galaxy). It operates across 0°C to 70°C in a 64-pin VQFN package and integrates an internal USB HID-to-I2C bridge for configuration and EEPROM programming.
For engineers reviewing the TUSB8043ARGCR datasheet, TUSB8043ARGCR pinout, TUSB8043ARGCR application, or TUSB8043ARGCR equivalent, key selection considerations include its 5 Gbps SuperSpeed hub functionality, 4 downstream ports plus internal HID-to-I2C port, support for DCP/CDP battery charging per YD/T 1591-2009, OTP/EEPROM/I2C configurability, and 24-MHz single-clock operation.
Technical Context
The TUSB8043ARGCR implements a Multi-Transaction Translator (MTT) architecture with four independent transaction translators and two asynchronous endpoint buffers per translator, enabling concurrent high-bandwidth USB 2.0 device handling. Its USB 3.2 x1 Gen1 interface supports U0/U1/U2 link states and dynamic speed negotiation based on upstream electrical environment-disabling SuperSpeed when upstream only supports HS/FS/LS.
It embeds a dedicated internal USB 2.0-only downstream port for HID-to-I2C bridging, operating at HS/FS speeds matching the upstream port, and supports I2C master clock stretching, 100 k/400 k EEPROM read, and vendor-defined requests for I2C/EEPROM access. Configuration is flexible via pin strapping, OTP ROM, or I2C/SMBus slave interface for VID/PID, port customizations, and strings.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar USB 3.x hub applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| USB7202-64 | 8-port USB 3.2 Gen1 hub with PCIe upstream interface; requires host-side PCIe root complex; no integrated HID-to-I2C bridge. | Targeted at PC motherboard or add-in card use where PCIe is available; not suitable for direct USB upstream connection. | Select USB7202-64 only when upstream connectivity is PCIe-based and higher port count is required; TUSB8043ARGCR remains optimal for USB-upstream dock/monitor applications. |
| TUSB8041ARGCT | Single-chip 4-port USB 3.2 Gen1 hub in identical 64-pin VQFN package; lacks internal HID-to-I2C port and supports only three downstream ports plus one upstream. | Used where I2C bridging is unnecessary and board space constraints match RGC footprint; no internal USB 2.0-only port for HID-to-I2C. | Choose TUSB8041ARGCT for simplified hub-only designs without configuration bridging needs; TUSB8043ARGCR is preferred when HID-to-I2C functionality is required. |
Compared with USB7202-64 and TUSB8041ARGCT, the TUSB8043ARGCR uniquely combines USB-upstream connectivity, four external downstream ports, and an integrated HID-to-I2C bridge-enabling both peripheral expansion and embedded system configuration in a single chip without PCIe dependency or external bridge ICs.

FAQ
What USB standards does the TUSB8043ARGCR support?
The TUSB8043ARGCR supports USB 3.2 x1 Gen1 (5 Gbps) and full USB 2.0 compliance, including high-speed (480 Mbps), full-speed (12 Mbps), and low-speed (1.5 Mbps) modes. It implements Multi-Transaction Translator (MTT) architecture for USB 2.0 and dynamically disables SuperSpeed functionality when the upstream port only supports USB 2.0 signaling-ensuring seamless interoperability across host generations. The TUSB8043ARGCR maintains full backward compatibility without requiring firmware updates.
Does the TUSB8043ARGCR include an integrated USB HID-to-I2C bridge?
Yes, the TUSB8043ARGCR includes a dedicated internal USB 2.0-only downstream port configured as a USB HID class interface that acts as an I2C master. This bridge supports 100 kHz and 400 kHz I2C operation, clock stretching, and vendor-defined requests for reading/writing I2C peripherals or EEPROM. It eliminates the need for external bridge ICs and enables direct USB-host control of onboard sensors, PMICs, or configuration memory-functionality confirmed in the TUSB8043ARGCR datasheet Section 1 and Pin Functions table.
How does battery charging work on the TUSB8043ARGCR?
The TUSB8043ARGCR supports multiple battery charging modes: CDP (Charging Downstream Port) when upstream is connected, DCP (Dedicated Charging Port) when upstream is unconnected and compliant with YD/T 1591-2009, ACP1–ACP3 (Divider Charging Port), Galaxy charging, and automatic mode transitions. Battery charging enable per port is controlled by PWRCTLx/BATENx pins sampled at reset, and charging handshaking occurs on D+/D− lines. These capabilities are fully documented in the TUSB8043ARGCR Features section and Section 5 Description (continued).
What package and thermal specifications apply to the TUSB8043ARGCR?
The TUSB8043ARGCR is packaged in a 64-pin VQFN (RGC) with nominal dimensions of 9.0 mm × 9.0 mm and requires connection of the exposed thermal pad to ground. Its thermal resistance is RθJA = 26°C/W, RθJC(bot) = 1.0°C/W, and it is rated for commercial operation from 0°C to 70°C. These mechanical and thermal parameters are specified in the TUSB8043ARGCR Device Information table and Section 7.4 Thermal Information of the official datasheet.
Can the TUSB8043ARGCR be configured without external EEPROM?
Yes, the TUSB8043ARGCR supports configuration via pin strapping (for basic features like battery charging mode), OTP ROM (for fixed VID/PID and port settings), or runtime I2C/SMBus slave interface. While external EEPROM enables field-updatable strings and configurations, OTP ROM provides permanent, factory-programmed settings without requiring external components. All three methods-including pin-strapped defaults-are validated in the TUSB8043ARGCR datasheet Sections 1 (Features) and 5 (Description continued).
