Code execution in ROM and EEPROM for Infineon SLE66xxPE chip

LYE KEE FOOK

I want to know is there any difference in code execution time between running code in ROM and EEPROM for infineon SLE66xxPE series of chips. I am developing a project based on infineon chip, and have a code running in SmartMask(EEPROM) and ROM-Mask. Is the ROM-Mask version supposed to run faster?

    That is very likely. If you run from internal ROM, there is no need for the chip to use its external bus to fetch instructions/data. In addition, the external device might be slower (compare: internal flash vs. NOR flash). Check access times and bus performance.
