There are not many PIC's that support external memory.

Take a look at some 17XXX and 18XXX derivates.

best regards
 

16fxxx use just internal eeprom for programms and data dont hus a external bus (address ,data and control bus) like processor or dsp

No it uses internal FLASH. The intenal EERPOM is not used to store the program.
The old and obsolete 16C84 used EEPROM to store the program, but the 16Fxxx devices uses FLASH.
