Memory Interfacing With 8086 Microprocessor Youtube There are various communication devices like the keyboard, mouse, printer, etc. so, we need to interface the keyboard and other devices with the microprocessor by using latches and buffers. this type of interfacing is known as i o interfacing. block diagram of memory and i o interfacing 8085 interfacing pins. following is the list of 8085 pins. Memory bank with that of the microprocessor 8086. 3. the remaining address lines of the microprocessor, bhe and ao are used for decoding the required chip select signals for the odd and even memory banks. the cs of memory is derived from the output of the decoding circuit. 4. as a good and efficient interfacing practice, the address map of the.

While interfacing memory to 8086 ensure that atleast 4k of rom is available in the last locations ending at location fffffh. this is due to the fact that on reset the first instruction is executed from location ffff0h. the 2k restriction is because the smallest memory chip available is 2k. 2k e and 2k o adds up to 4k. Typically problem is to place devices within memory map. determine start, size, lo (=start), hi (=lo size 1) determine const, sel, and mem address lines. 3) generate overall chip select signal (msel) from const portion of address range and m io. 4) generate bank specific write signals if required.
