In the 8085 microprocessor, the time required to complete one memory read cycle is typically 3 to 4 machine cycles, which translates to 3 to 4 microseconds depending on the clock frequency used. Each machine cycle consists of a series of states, including address setup, memory read, and data retrieval. The specific duration can vary based on the operating speed of the microprocessor, usually running at a clock frequency of 3 MHz to 6 MHz. Thus, the overall time can vary but is generally within the range of a few microseconds.
What else can I help you with?
What is memory word size required in an 8085 system?
In an 8085 system, the memory word size required is 8 bits. This means that each memory location can store 8 bits or one byte of data. The 8085 processor accesses memory locations using these 8-bit memory addresses to read or write data during program execution. The memory word size of 8 bits allows the 8085 system to handle data in small, manageable chunks efficiently.
How many memory location can be addressed by microprocessor 8085?
The 8085 can address 216, or 65536 different memory locations.
What is slow memory interfacing?
explain how slow memory get interfaced with 8085
How many machine cycles requires to complete the execute IN 84H in 8085?
The instruction IN 84H in the 8085 microprocessor requires 5 machine cycles to complete. This includes 1 opcode fetch cycle and 4 memory read cycles. The opcode fetch retrieves the instruction from memory, while the read cycles are used to read the data from the specified input port.
Which is used to connect low memory in 8085?
READY
Which of the data transfer is not possible in 8085 microprocessor?
In the 8085 microprocessor, direct data transfer between two memory locations is not possible. Data must first be loaded into a register from one memory location and then stored into another memory location. The 8085 can only transfer data between registers, memory, and I/O devices using specific instructions, but it does not support direct memory-to-memory transfers.
The minimum ICs required for 8085 to start working properly?
the minimum number ICs required for 8085 to start working properly are 3
IN 8085 local variables will get stored in?
Registers or RAM-memory.
What is memory word addressing capability of 8085 µp?
64K
What is memory address register of Intel 8085?
8 bits
How many memory address can by address by 8085?
64 kb
How much maximum memory size that 8085 can access?
Yes and no. All memory location from 0H to 0FFFFH are addressable, but some of them are needed for the program, interrupt vectors, and the stack, so you would need to pay attention to where things are located in memory to design an appropriate program. In addition, if your system is using memory mapped I/O, some locations will be reserved.
