Interfacing a memory card with AT89C52 for storing the code

[Help]

Re: AT89C52 code size

Hi,

From my simulation result. When power-up the U10 and U15 show using BANK1 PG3. If power-up the initial bank is not BANK0 (EPROM) then how the EPROM data can be read?

Please have a look the simulation result.

Thank you.

Re: AT89C52 code size

I am not very enthusiastic about simulations like that ..

For the initial test you don't need any SRAM, just the EPROM ..
Try to test the circuit with 8051+TTLs+EPROM+RS-232 and let's hope you will see the opening screen while running the HYPERTERMINAL ..

Rgds,

i need c program to interface SRAM with 8051

Please give the program to interface SRAM with 8051
