Product details
Overview
CYUSB2302-68LTXIT from Infineon is a USB 2.0-only hub controller supporting two downstream ports, integrated ARM® Cortex®-M0 CPU (16 KB RAM, 32 KB ROM), USB Battery Charging v1.2 compliance, industrial temperature range (–40°C to +85°C), and 68-pin QFN (8 × 8 × 1.0 mm) packaging. It enables embedded docking stations with ganged power switching and pin-strapped configuration.
For engineers reviewing the CYUSB2302-68LTXIT datasheet, CYUSB2302-68LTXIT pinout, CYUSB2302-68LTXIT application, or CYUSB2302-68LTXIT equivalent, key selection criteria include USB 2.0 hub topology support, BC v1.2 charging capability per port, I2C-based firmware update, shared-link absence (vs. CYUSB33xx), and industrial-grade thermal operation without SS PHY.
Technical Context
The CYUSB2302 implements a dedicated USB 2.0 hub controller with four transaction translators (Multi-TT), full LS/FS/HS support (1.5/12/480 Mbps), and LPM states (L0–L3). It lacks SuperSpeed (5 Gbps) PHY and SS hub logic - distinguishing it from CYUSB33xx variants.
Its ARM® Cortex®-M0 subsystem manages port power control, BC v1.2 DCP emulation, LED indicators, GPIO configuration for overcurrent detection, and vendor-command execution for USB-to-I2C bridging - all without requiring external microcontroller coordination.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Downstream Ports | 2 USB 2.0 ports (no SuperSpeed); supports simultaneous LS/FS/HS devices |
| Data Rate | Up to 480 Mbps (High-Speed); no 5 Gbps capability - excludes SS PHY |
| Charging Support | USB BC v1.2 compliant on both DS ports; enables DCP emulation during host disconnection |
| CPU Core | ARM® Cortex®-M0 with 16 KB RAM + 32 KB ROM; executes firmware for port control and I2C bridge |
| Package | 68-pin QFN (8 × 8 × 1.0 mm); exposes VBUS detect, LED, OVR, PWR, I2C, and GPIO signals |
| Temperature Range | –40°C to +85°C industrial grade; validated for sustained operation in enclosed dock/monitor enclosures |
| Power Switch Control | Ganged mode only; single enable signal controls both DS port VBUS - reduces external FET count |
Pinout & Package
68-pin QFN package (8 mm × 8 mm × 1.0 mm body height, 0.4 mm pitch), thermally enhanced with exposed pad. Pin functions verified per Infineon datasheet 001-73643 Rev. *V Sections 5 and 6.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| DP/DM (US) | Upstream differential pair | Connects to host controller; HS/FS/LS signaling only - no SS lanes |
| DP/DM (DS1, DS2) | Downstream differential pairs | Each supports full USB 2.0 speed negotiation; no SS routing required |
| PWR1/PWR2 | Port power enable outputs | Ganged control - both pins assert simultaneously to drive external high-side switches |
| OVR1/OVR2 | Overcurrent detect inputs | Active-low signals monitoring current sense resistors; trigger automatic port disable |
| LED1/LED2 | Port status indicator drivers | Open-drain outputs for suspend/active indication; compatible with 3.3 V LED circuits |
| I2C_SDA/I2C_SCL | I2C interface | Supports EEPROM configuration, firmware update, and USB-to-I2C bridging at 400 kHz |
Key Features
| Feature | Design Value |
|---|---|
| USB Battery Charging v1.2 | Enables DCP emulation on both DS ports when upstream host is absent - sustains smartphone/tablet charging in docked mode |
| Ganged Power Switching | Single control signal drives both DS port VBUS lines - eliminates need for dual independent power FETs and gate drivers |
| Integrated Cortex®-M0 Subsystem | Executes real-time port management, BC v1.2 state machine, and vendor-command I2C bridging without external MCU |
| I2C-Based Configuration | Accepts VID/PID, string descriptors, and port settings from external EEPROM - removes requirement for strapping resistors or eFuses |
| Industrial Temperature Operation | Validated performance across –40°C to +85°C ambient - suitable for fanless monitors, set-top boxes, and factory automation docks |

Equivalent & Alternatives
The following parts are listed as comparable options for similar USB 2.0 hub controller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| USB2514B-AEZG | 4-port USB 2.0 hub; no integrated CPU; requires external EEPROM for VID/PID; no BC v1.2 support | Lacks charging capability and firmware programmability - limited to basic data hubs | Select when cost-sensitive, non-charging applications require higher port count and simpler configuration |
| CY7C65642-56LTXI | 4-port USB 2.0 hub; no ARM core; no BC v1.2; supports only pin-strapped configuration; 56-pin QFN | No DCP emulation or I2C bridging - unsuitable for docked charging or firmware-upgradable systems | Choose for legacy designs where minimal footprint and fixed configuration outweigh advanced charging and programmability |
Compared with USB2514B-AEZG and CY7C65642-56LTXI, CYUSB2302-68LTXIT uniquely integrates BC v1.2 charging, Cortex-M0 programmability, and industrial temp operation - making it optimal for intelligent, self-contained USB 2.0 docking solutions.

FAQ
Does CYUSB2302-68LTXIT support SuperSpeed (5 Gbps) USB operation?
No. CYUSB2302-68LTXIT is a USB 2.0-only hub controller with HS/FS/LS support up to 480 Mbps. It lacks SuperSpeed PHY and SS hub logic - confirmed by its product option table (Table 1) and block diagram in datasheet 001-73643 Rev. *V. For 5 Gbps support, consider CYUSB33xx variants.
Can CYUSB2302-68LTXIT emulate a Dedicated Charging Port (DCP) without host connection?
Yes. The device implements USB Battery Charging v1.2 specification and supports ghost charging - enabling each downstream port to emulate a DCP and deliver up to 1.5 A when no upstream host is detected. This behavior is controlled by the integrated Cortex-M0 and requires no external components.
What configuration methods does CYUSB2302-68LTXIT support?
CYUSB2302-68LTXIT supports I2C EEPROM configuration and pin-strapping (per Table 1). Unlike some CYUSB33xx variants, it does not support eFuse or I2C master-mode configuration. VID/PID, port enable states, and power switch polarity are configurable via I2C or hardware straps.
Is the 68-pin QFN package of CYUSB2302-68LTXIT lead-free and RoHS-compliant?
Yes. The "LTXIT" suffix denotes lead-free, RoHS-compliant, and halogen-free packaging per Infineon's material declarations. The 68-pin QFN meets JEDEC standard MS-026, with NiPdAu terminal finish and matte tin lead plating.
