TUSB8041 datasheet

 

Description

The TUSB8041 is a four-port USB 3.0 hub. It provides simultaneous SuperSpeed USB and high-speed/full-speed connections on the upstream port and provides SuperSpeed USB, high-speed, full speed, or low-speed connections on the downstream ports. When the upstream port is connected to an electrical environment that only supports high-speed or full-speed/low-speed connections, SuperSpeed USB connectivity is disabled on the downstream ports.

When the upstream port is connected to an electrical environment that only supports full-speed/low-speed connections, SuperSpeed USB and high-speed connectivity are disabled on the downstream ports.

Features

1. Four Port USB 3.0 Hub

2. Multi Transaction Translator (MTT) Hub: Four Transaction Translators

3. Four Asynchronous Endpoint Buffers Per Transaction Translator

4. Single Clock Input, 24-MHz Crystal or Oscillator

CH341A USB Bus Convert Chip

Description

The CH341A is a USB bus convert chip, providing UART, printerport, parallel and synchronous serial with 2-wire or4-wire through USB bus. In UART mode, CH341 provides alternant rate control signals such as serial transfer enable, serial receive in ready etc. It also supplies common MODEM communication signal in order to expand UART for computer orupgrade common synchronous interface device to USB bus directly.

In printer port mode, CH341 supplies standard USB printerport which compounds USB relevant protocol and Windows operate system used toupgrade ordinary parallel printer to USB bus directly. In parallel mode, CH341 gives out8-bit parallel in EPP or MEM mode. It canbe used to input/output data directly without MCU/DSP.
