How to use ROM of LPC2148(if available)

Hello I wanted to use Internal EEPROM(if available in LPC2148 to access)
as I have gone through the datasheet of LPC2148 and I have not found any register to access ROM so i started thinking to use External I2C Eeprom like AT24C256,

So if there is a way to access internal ROM/EEPROM of LPC2148,
Please Guide me to do so or if it is not accessed then give me a direction as i am having on a Project which saves some Strings in ROM to be Compared with the user INPUT value via sensors and Keypad

Please Guide me if there is accessibility to use INTERNAL ROM (if yes how like tell me the steps )or i should use EXTERNAL EEPROM,

Thanks in advance

  • There are no internal EEPROM in that processor - and the processor documentation should make that clear.

    There is the flash memory used for storing the program. And the user manual (strange to think things might be described in a manual, without need to ask on a forum...) contains information how to make use of IAP - In Application Programming - to make a user program perform writes to this memory. But the flash memory sectors only supports a limited number of erase cycles before wearing out. So it's ok to store configuration there but not a good place to store regularly changing state information.
