Hex, Bix files and the Hex2bix Utility

Last Updated: November 25, 2011

How do you convert files from the hex format to the bix or i2c format?. What is the difference between the .hex file and the .bix file? What is the Hex2Bix Utility?


Hex files are ASCII representations of binary data (bix). For a discussion of the hex file format see

The hex2bix utility is provided to assist in converting a hex formated file to the bix format to create iic images to load in your serial EEPROM. The .IIC files can be downloaded to the EEPROM using the EZ-USB CyConsole or Control Centre utility. The Hex2bix utility tool is present under C:\Cypress\USB\bin once the CY3684 EZ-USB FX2LP Development Kit is completely installed. The hex2bix utility is a DOS program. A detailed description of how to go about using the utility is present in application note  Using the Hex2bix Conversion Utility-AN45197.
