Then you only need to know how to replace ATMEGA8535 by AT89C51. I recommend datasheets for that. Find what additional hardware feature is present in ATMEGA8535 and implement it by additional hardware with AT89C51.

The problem persists with serial peripheral interface controller in ATMEGA chip. Also as recording is done at very high speed i need to interface a FLASH instead of EEPROM. Can you suggest some solution?

What are the specs of that SPI controller? You use the direct cross components for that. Check on various websites of manufacutres for direct cross. I will go through it and will let you know if any.

Specify the speed. Instead can you not use your PC for that. With serial interface. You will get very high baud rates.
