parallel EEPROM AT28C16 with 8051

[amol chaudhari]

Someone please help me out in interfacing parallel EEPROM 28C16 with 8051.
using latch 74373, i want to multiplex address and data on port P0.
I am using C coding..
Can it be done using XBYTE [] instruction and ALE pin as latch pulse
or using 1 port pin for latch control is better?

For proper timing use ALE.

XDATA is used for RAM then how will it work for ROM . what will happen if we connect both external RAM and ROM  in which memory will XDATA variable be stored.and how to save in other memory then be it rom or ram

first tell me why do u require additional EEPROM?

internal memory is not enough? AT89C52 has 8K internal EEPROM. still u need external memory?

even u can use P89V51RD2 with 64K internal EEPROM
