PPT-Introduction to 8085 Microprocessor

M Mahesh Babu Introduction to 8085 Introduced in 1977 It is 8bit MP It is a 40 pin dualinline chip It uses a single 5V supply for its operations Its clock speed is about 3MHz Features of 8085. Meets the requirements of the European Std EN 12469 for microbiological safety cabinets Provides you with the highest level of operator safety to protect you and your personnel from the hazardous compounds used in cytotoxic drugs Motorized sash help Common means of modulating data in digital communication Key advantage is that I can send mu ltiple signals using Time Division Multiplexing There are several pulse modulation techniques Pulse Amplitude Modulation Pulse Width Modulation Pulse cornelledu Abstract Microprocessor simulators are very popular in re search and teaching environments For example func tional simulators are often used to perform architectural studies to fastforward over uninteresting code to gener ate program trace Address Decoding. Topics to be discussed. ADDRESS DECODING . A simple NAND gate decoder . Sample Decoder Circuit . The Dual 2-to-4 Line Decoder (74LS139) . PLD Programmable Decoders . ADDRESS DECODING.
