How many EEPROM addresses in a PIC18F458 ?
PostPosted: Tue Feb 21, 2006 3:50 am     Reply with quote
Hello,

when i use write_eeprom() and read_eeprom() functions, which is the last address of the EEPROM on a PIC18F458 ?
I used for now write_eeprom(0x14, 1); without any problem, can i go to 0x30 or more ?

Please let me know.
Thank you
Best regards.

How much effort did you put into searching for this information?
On page 2 of the PIC18FXX8 datasheet you find the eeprom has a size of 256 bytes.

Another easy source of information would have been the pic18f458.h header file supplied with your compiler:
Code:
//////// Standard Header file for the PIC18F458 device ////////////////
#device PIC18F458
#nolist
//////// Program memory: 16384x16  Data RAM: 1536  Stack: 31
//////// I/O: 34   Analog Pins: 8
//////// Data EEPROM: 256
//////// C Scratch area: 00   ID Location: 2000
