how much the rate of read form a usb flash?

[jason_bill]

Hi

I have a buffer (in microcontroller) and must read data from it at 112Mbits/s that this data saved in a memory.

now i want to understand that, can i use a usb flash as memory that this data stored on it and then read the data from it with speed rate more than 112Mbits/s and save in my buffer?

in wiki is mentioned that" higher maximum signaling rate of 480 Mbit/s (effective throughput up to 35 MB/s or 280 Mbit/s) (now called "Hi-Speed")".

Thanks.

Are you sending data to micro's buffer? If yes, does your micro really have that much memory to store atleast 112 MBits which come in 1 sec? You want to store data to some memory like SD card or USB flash?

You want to interface pen drive to micro?

thanks for reply

actually i didn't decide how to save and send data exactly, and of course, my intention about that i mention above is : micro receive data from a memory for example usb flash (because i think usb flash is just way that i receive data at 112 Mbits/s and more), and then write in a limited buffer and controlled such whether there is an empty entry to save a new data or there is an entry that rad and sent out its data.

You want to store data to some memory like SD card or USB flash?

yes, but also i have nand flash in minde, i must mention that i need a memory with at least 4 Gbyte capacity.


i don't want to use any external ram for buffering, and my micro, i think at least has 1 kbyte for buffering.

You want to interface pen drive to micro?

if your intention is "usb flash", yes, and just as a memory that store my data and then send them through a micro on SMA connector at 112Mbits/s.

thanks.
