UART (USB to EEPROM) DATA transfer

[ajinkyarp]

Hello,
I want to build the board in which data are taken from computer and sent to EEPROM. I searched different websites and found that FTDI FT232 is used for communicating between computer and devices. I have to send data to EEPROM through computer which is of 32bits. How to approach and build the circuit? Also I want to know which software is used to write data on computer which will be sent to COM port and further to EEPROM.

Hi,

Not very informative.
What EEPROM? Inside a microcontroller? External parallel, serial, what interface...?

What does "32 bits" mean.
An EEPROM has data and address. What size?
What amount of data per time?

Do you want to use a microcontroller between FT232 and EEPROM? Which one?
What protocol?

The EEPROM is Outside and I am not using any kind of microcontroller. I want to use serial interface. I want to use UART serial protocol.
I have to send 32 bits serially at clock of 5MHz to a data pad of Integrated Circuit (IC) from computer using EEPROM amid. EEPROM can be of 1kb i.e. 24c01 since at a time I have to use only 32bit of EEPROM.

By using FTDI bit bang mode you can handle pins of the USB/Serial converter in such a manner that you can implement a two wire protocol, assuming that you are refererring to some SPI or I2C EEPROM.
