Do I have to use microcontroller in the USB peripheral side?

[maolh]

I want to develop a data acquistion device which uses USB to communicate with PC. Do I have to use a microcontroller to implement the USB protocol? I am new to USB field, so please forgive me for my silly question.

try ftdi chips solutions. they products usb 2 rs232 ,i2c, spi converter. they olso sends free samples

Re: Do I have to use microcontroller in the USB peripheral s

another solution is to use a microcontroller with build in USB like cygnal

I think that you need to use microcontroller to handle the communication between the device and the PC, also u need to add extra circuitry to the design.
Some microcontrollers have a build in Analog to digital converter (ADC), so you can use this ADC to acquire the data, and then you can send the data to the computer using the microcontroller through USB....

AT89C5131 from ATMEL have USB peripheral 32KBYTE FLASH MEMORY,
256BYTE RAM, FULL DUPLEX UART, 1024BYTE ERAM, DUAL DTA POINTE,
WATCH DOG, USB, PCA

Hi,
You have two options

1) Microcontroller with USB functionality
2) external microcontroller for handling some functions.

You need microcontroller to handle the data storage/ endpoint configuration.

i already developped a data acquisition system using usb
i used ez-usb kit
to communicate over usb ur hardware should have a usb core
there are alot of microcontrollers having a built in usb core
u can check cypress, fairchild or atmel websites for more information

The NEW FTDI chip the 232C has a MCU EMULATION MODE ..it can simulate a exactly a 8051 BUS with all the standard signals ALE,/WR,/RD a chip select /CS a 16 bit address bus and a 8 bit data bus. So whatever peripheral can be connected to a 8051 can also be connected to it .You send through the DRIVERS the address and the data and a CODE for a write cycle or for a read cycle ..
simple ,elegant . NEVER USB has been so easy !

Hi nooknikz!
do you have experience with ATMEL AT89C5131?

Hi Madhukar!
I'm going through USB specs! i have few doughts? will you help me out?
