1. An 8085A microprocessor based system has the following memory chips and I/O devices. The relevant control pins of each chip are also indicated: RAM 6264(4Kx8): OE, WE, CS EPROM 2764(8Kx8): OE, CS 8-LEDs and 8-Toggle switches. 2 chips 1 chip Develop the system bus of the system including the RESET circuit using 74LS373 latch. Design an interfacing circuit to interface ROM, RAM and I/O devices. I/O devices are interfaced using standard I/O. Give addresses of memory and I/O devices. Use 74LS138 (3Lx8L decoder having two active LOW and one active HIGH enable inputs) for interfacing. Use Fold Back Addresses to simplify the interfacing circuit. [10]
