Understanding the 8085 begins with its fundamental technical specifications:
Contains approximately 6,500 transistors on a single chip The "5" in 8085 signifies that it uses a Multiplexed Address/Data Bus ( After every ALU operation,
): Pins 21 to 28 carry the most significant 8 bits of memory addresses. These lines are unidirectional. Multiplexed Address/Data Bus (
After every ALU operation, the update a report on the result. These are five single-bit flip-flops that record specific conditions, which are crucial for making decisions in a program.
The 8085 is housed in a 40-pin Dual In-line Package (DIP). These 40 pins are organized into functional signal groups: Address Bus (
): The upper 8 bits of the memory address. These lines are unidirectional. Multiplexed Address/Data Bus (
