Other Parts Discussed in Thread: TUSB2036, TUSB3410

I need some help. Can i use TLK100 for Ethernet and TUSB3210 or TUSB2036 for USB connectivity  with my controller board? or should I use some thing else. as I never worked with USB, I dont nkow which chip should I use. After suggestion I want to study that chip and usb connectivity. PLS help..

Thanx for your kind attention .

    Hi Shamik,

    TLK100 is just the PHY; for Ethernet connectivity you need to have the MAC (extra component or integrated into your DSP/MCU) too. 

    Regarding USB connectivity, TUSB3210 (which has a 8051 core) could be a choice. TUSB2036 is only for USB HUB applications, so if you do not want to build a USB hub you shouldn't use this one.

    If you're thinking about an MSP430 with USB connectivity you should have a look at the new MSP430F5529 (i.e.) since it has a USB interface embedded (no extra components needed). You should also have a look at TUSB3410 which is a Serial-to-USB converter which you can connect to the UART of every MCU.

    To,

    Thanx for your kind information,

    could you suggest me the replacement for ENC28J60.  2) is TUSB3410 is the simplest or any other chip available for communication for usb to microcontroller chip, I am not using MSP430 as my board is devloped with AVR.

    Thanx & Regards

    Shamik.

    Hi Shamik,

    well, the Microchip ENC28J60 is a Stand-Alone Ethernet Controller which connects to the SPI interface of the Host MCU; so why not using it (since I don't know if TI has such devices). In case of USB connectivity, the TUSB3410 would be a perfect choice.  Connect it to your AVRs UART and thats it. Have a look at the application notes on the TUSB3410 product page. An alternative would be FT232 (http://www.ftdichip.com/Products/FT232BM.htm).

    P.S. Why adding up lots of parts (and money) when you could have a SOC solution? Have a look at the Stellaris ARM Cortex M3 based products, i.e. http://www.luminarymicro.com/products/lm3s9790.html .
