INTEL 8085

This chapter describes hardware, software, and interfacing aspects of the Intel 8085. Topics include 8085 register architecture, addressing modes, instruction set, input/output, and system design.

2.1    Introduction

The Intel 8085 is an 8-bit microprocessor. The 8085 is designed using NMOS in 40-in DIP (Dual In-line Package). The 8085 can be operated from either 3.03 MHz maximum (8085A) or 5 MHz maximum (8085A-2) internal clock frequency.

The 8085 has three enhanced versions, namely, the 8085AH, 8085AH-2, and 8085AH-1. These enhanced processors are designed using the HMOS (High-density MOS) technology. Each is packaged in a 40-pin DIP like the 8085. These enhanced microprocessors consume 20% lower power than the 8085A. The internal ...
