|
|
The DIP TUSB3410 module utilizes the TI TUSB3410 USB full-speed peripheral IC and integrates all the components needed to run with or without exteranl components.
This module is designed for bus powered application and has a standard (24-pin), 0.6in wide footprint. The total size (including USB-B type connector) is less than a standard 40-pin(0.6in) IC. It can be installed into a prototype board as a standard IC or directly inserted into your bread board.

PWR* |
3.3V Regulated PWR. It may power external circuit with max current 200mA |
|
24 |
PWR* |
5V USB BUS +5V. Use with care |
*IMPORTANT: The module is bus powered, so NEVER apply external 3.3V and/or +5V to the module. The 3.3V and 5V PWR can power external circuit only. You can consider these two pins are output.
The pin size is: 0.025" (0.64mm) square.
You can downlaod the schematic (PDF file) here.
Software Tools
The module is based on TI TUSB3410 chip, which is a full speed USB peripheral controller with standard 8082 core, so any 8052 development tools can be used for it. Keil and IAR C compilers are popular and very reliable compilers. A wide range of options are available for software development, including free assembly language tools and SDCC free C compiler.
Drivce drivers
In general, the TI AppLoader Driver is needed to load your 8052 code from host PC through the USB port into this module. The exception is that you only want your code downloaded from serial EEPROM through the I2C bus.
The TI AppLoader Driver is a Windows USB device driver that enables firmware for TI's TUSB3410 device to be kept on the PC rather than in the USB device's EEPROM. When a USB system using this device is inserted onto the bus, Windows associates it with this driver, which downloads the firmware to the device.
This driver can be downloaded through my download section or from TI.
