command for read & write at epromp 16f72

[ryad_shabbir]

Dear
at 16f84 i can read using the command read_eeprom (address) and can write using write_eeprom (address, value)

can u please tell me the command of 16f72 for read and write data.

Does the 16F72 have internal EEPROM?

Actually i am very new at this field.

Dear jalonso, I dont know whether it has EEPROM or not, i am just using the PIC IC 16f72.

Dear keith1200rs , I am using CCS pic c compiler.

It will be great help for me if i get the correct code to save data as i did it at 16f84a
using the code write_eeprom (address, value)

Thanks
Ryad

Hi,

PIC16F72 does not have an internal EEPROM where you can store data as in 16F84A, so you will be unable to save data if you use a 16F72 (unless you use an external memory...).
16F84A microcontroller has an internal EEPROM that can be used to write/read data using the CCS functions "write_eeprom" and "read_eeprom". As PIC16F72 has no place to store data, these CCS functions will do nothing...

You can refer to the following table from Microchip, to select another PIC16-family microcontroller with "EEPROM Data Memory":
