TUSB3410  USB TO SERIAL PORT CONTROLLER

 

1.Controller Description

The TUSB3410 provides bridging between a USB port and an enhanced UART serial port. The TUSB3410 contains all the necessary logic to communicate with the host computer using the USB bus. It contains an 8052 microcontroller unit (MCU) with 16K bytes of RAM that can be loaded from the host or from external on-board memory via an I2C bus. It also contains 10K bytes of ROM that allow the MCU to configure the USB port at boot time. The ROM code also contains an I2C boot loader. All the device functions such as the USB command decoding, UART setup, and error reporting are managed by the internal MCU firmware under the auspices of the PC host.

The TUSB3410 can be used to build an interface between a legacy serial peripheral device and a PC with USB ports, such as a legacy-free PC. Once configured, data flows from the host to the TUSB3410 via USB OUT commands and then out from the TUSB3410 on the SOUT line. Conversely, data flows into the TUSB3410 on the SIN line and then into the host via USB IN commands.

NOTES:

1. 3-state CMOS output (±4-mA drive/sink)

2. 3-state CMOS output (±8-mA drive/sink)

3. 3-state CMOS output (±12-mA drive/sink)

4. TTL-compatible, hysteresis input

5. TTL-compatible, hysteresis input, with internal 100-µA active pullup

7. Normal or IR mode: 3-state CMOS output (±4-mA drive/sink)

8. The MCU treats the outputs as open drain types in that the output can be driven low continuously, but a high output is driven for two clock cycles and then the output is tristated.
