Introduction

AI Translation

The TUSB8040A is a four-port USB 3.0 compatible hub in a 100-pin QFN package, designed for operation over the commercial temperature range of 0°C to 70°C. The TUSB8040A provides simultaneous SuperSpeed USB and high-speed or full-speed connectivity on the upstream port, and SuperSpeed USB, high-speed, full-speed, or low-speed connectivity on the downstream ports. When the upstream port is connected to an electrical environment that supports only high-speed, full-speed, or low-speed connectivity, SuperSpeed USB connectivity on the downstream ports is disabled. When the upstream port is connected to an electrical environment that supports only full-speed or low-speed connectivity, both SuperSpeed USB and high-speed connectivity on the downstream ports are disabled. The TUSB8040A supports up to four downstream ports and can be configured to report one to four downstream ports via pin selection, a connected EEPROM, or an SMBus controller. This configuration option provides the ability to scale the device per application.

Features

AI Translation
  • Upstream port supports SuperSpeed USB, high-speed, and full-speed connections
  • Four downstream ports supported, each with SuperSpeed USB, high-speed, full-speed, or low-speed connectivity
  • Multi-Transaction Translator (MTT) hub: four Transaction Translators, one per port
  • Four asynchronous endpoint buffers per TT for improved data throughput over TTs with the USB-required minimum of two buffers
  • Supports operation as a USB 3.0 or USB 2.0 composite device
  • Per-port or ganged power switching with overcurrent notification input
  • Status outputs: high-speed upstream connection, high-speed upstream port suspended, SuperSpeed USB upstream connection, SuperSpeed USB upstream port suspended
  • Optional serial EEPROM or SMBus controlled interface for custom configuration: VID/PID, manufacturer and product strings, serial number
  • Each downstream port individually configurable via pin strapping or EEPROM/SMBus controlled interface: enable/disable, removable or permanently attached (for composite applications), battery charging enable/disable
  • 128-bit Universally Unique Identifier (UUID)
  • Optional USB 2.0 compatible port indicator LED support
  • Configurable SMBus address for multiple devices on the same SMBus segment
  • On-board and in-system EEPROM programming via USB 2.0 upstream port
  • Single clock input, 24MHz crystal or oscillator
  • No special driver requirements; seamless operation with any USB stack-supporting OS
