Introduction The Intel 8085 is an 8-bit microprocessor introduced in the mid-1970s. R. Gaonkar’s widely used textbook and accompanying lecture PPTs present the 8085 architecture, instruction set, programming model, timing, and interfacing fundamentals in a clear, course-focused way. This article summarizes core topics a student or instructor would expect from “8085 PPT by Gaonkar.”
The 8085 features a robust interrupt system, essential for real-time applications:
8-bit wide, determining the processor's word size. Address Bus: 16-bit wide, allowing it to address up to bytes (64 KB) of memory. Clock Speed: Operates at a standard frequency of 3 MHz.
