The Memory Interfacing in 8085 is used to access memory quite frequently to read instruction codes and data stored in memory. This read/write operations are 1. First decide the size of memory requires to be interfaced. · 2. Depending on the size of memory required and given address range, construct address · 3. The Memory Interfacing in 8085 is used to access memory quite frequently to read instruction codes and data stored in memory. This read/write operations are memory and the microprocessor requires some signals to read from and write to Following is the list of 8085 pins used for interfacing with other devicesAddress Space Partitioning: • The Intel8085 uses a 16-bit wide address bus for addressing memories and I/O devices. • Using 16-bit wide address bus it can INTERFACING OF 8085 TO MEMORY. EXAMPLE: DESIGN THE INTERFACE FOR INTERFACING SINGLE CHIP. OF 64K MEMORY WITH 8085MP. 1. Memory of 64K capacity needs 16 Memory interfacing includes 3 steps : 1. Select the chip. 2. Identify register. 3. Enable appropriate buffer. 8085 Memory Interfacing • Example: Interface Let us assume that we have a microcomputer built using the 8085 which has 2 K bytes of ROM and 256 bytes of RAM. Figure 19.1 shows the memory map of the scheme.
