Introduction

AI Translation

CH334 and CH335 are 4-port USB hub controller chips compliant with the USB 2.0 specification. The upstream port supports USB 2.0 high-speed and full-speed modes, while the downstream ports support USB 2.0 high-speed 480Mbps, full-speed 12Mbps, and low-speed 1.5Mbps. They support both the low-cost STT mode (a single transaction translator time-sharing across 4 downstream ports) and the high-performance MTT mode (4 transaction translators each dedicated to one port for concurrent processing). Designed to industrial-grade standards with a minimal peripheral circuit, these chips are suitable for computer and industrial PC motherboards, peripherals, and embedded systems.

Features

AI Translation
  • 4-port USB hub with 4 USB 2.0 downstream ports, backward compatible with USB 1.1
  • Per-port individual power switching or ganged power switching
  • Per-port individual over-current detection or ganged over-current detection; supports 5 V over-current signal input
  • High-performance MTT mode with dedicated transaction translator per port for full-bandwidth concurrent transfers; total bandwidth is 4× that of STT mode
  • Per-port status LED indication
  • Compound device support, non-removable device, custom VID, PID, and port configuration via external EEPROM
  • Built-in information memory for bulk customization of vendor/product information and configuration for industry-specific requirements; no external EEPROM required
  • Proprietary USB PHY with LPM low-power technology; significantly reduced power consumption vs. first-generation hub ICs; supports self-powered and bus-powered modes
  • Self-powered or bus-powered mode configurable via I/O pins or external EEPROM
  • Crystal oscillator with built-in capacitors; supports external 12 MHz clock input; integrated PLL provides 480 MHz clock to USB PHY
  • Built-in high-precision internal clock; optional elimination of external 12 MHz crystal to reduce cost, board area, and EMI
  • Built-in 1.5 KΩ pull-up on upstream port; built-in host-required pull-downs on downstream ports; minimized external components
  • Integrated LDO regulator converts USB bus voltage to 3.3 V operating voltage
  • CH335 supports MCU-controlled swapping between upstream port and downstream port 1
  • USB pins with 6 KV enhanced ESD protection, Class 3A compliant
  • Industrial temperature range: -40 ~ 85℃
  • Available in QFN28, QFN24, QFN16, and QSOP28 packages
