Microprocessor 8085 Ppt By Gaonkar Free |top| Jun 2026

The 8085 is an 8-bit general-purpose microprocessor capable of addressing 64 KB of memory. Developed by Intel in the mid-1970s, it is a classic example of . Key Specifications: Data Bus: 8-bit (carries data between the CPU and memory). Address Bus: 16-bit (can address memory locations). Clock Speed: Typically 3 MHz. Technology: NMOS, requiring a single +5V power supply. 2. Architecture and Register Organization

The 8085 has five hardware interrupts, prioritized as follows: (Highest priority, Non-maskable) RST 7.5 RST 6.5 RST 5.5 INTR (Lowest priority) 6. Why Use Gaonkar’s Materials?

A 16-bit register that manages the stack memory, crucial for subroutine calls. microprocessor 8085 ppt by gaonkar free

State: The microprocessor places the 16-bit address on the address bus. ALEcap A cap L cap E goes high to latch the lower 8 bits ( T2cap T sub 2 State: RD¯modified cap R cap D with bar above

Contains five status flags: Carry (CY), Parity (P), Auxiliary Carry (AC), Zero (Z), and Sign (S). 3. The 8085 Instruction Set

The time required to access memory or an external I/O device. Common cycles include Opcode Fetch, Memory Read, and Memory Write. The 8085 is an 8-bit general-purpose microprocessor capable

An 8-bit register containing 5 active flags (Sign, Zero, Auxiliary Carry, Parity, Carry). 3. The 8085 Bus Structure and Pinout The 8085 uses multiplexing to save pins.

B, C, D, E, H, and L (can be combined as 16-bit pairs: BC, DE, HL).
