What is the power supply of 8085?
+5V
How many registers are there in 8085 microprocessor?
six
What is the use of microprocessor 8085?
8085 is pronounced as “eighty-eighty-five” microprocessor. It is an 8-bit microprocessor designed by Intel in 1977 using NMOS technology. It is used in washing machines, microwave ovens, mobile phones, etc.
How many output pins are there in 8085?
What is 8085 Microprocessor? The 8085 microprocessor is an 8-bit general purpose processor that can deal with the memory of 64K Byte. This microprocessor consists of 40-pins as well as works with +5V power supply.
What is the function of ready pin in 8085?
Ready: This is an active high input control signal. It is used by microprocessor to detect whether a peripheral has completed (or is Ready for) the data transfer or not. The main function of this pin is to synchronize slower peripheral to faster microprocessor.
What is the function of intr pin in 8085 microprocessor?
INTR – It is an interrupt request signal. INTA’ – It is an interrupt acknowledgement sent by the microprocessor after INTR is received.
What are the features of 8085 microprocessor?
Features of 8085 Microprocessor:
- 1.It is an 8-bit microprocessor i.e. it can accept, process, or provide 8-bit data simultaneously.
- 2.It operates on a single +5V power supply connected at Vcc; power supply ground is connected to Vss.
- 3.It operates on clock cycle with 50% duty cycle.
- 4.It has on chip clock generator.
Why do we use intr?
INTR. The INTR is a maskable interrupt because the microprocessor will be interrupted only if interrupts are enabled using set interrupt flag instruction. It should not be enabled using clear interrupt Flag instruction. The INTR interrupt is activated by an I/O port.
What is the purpose of Inta?
The International Trademark Association (INTA) is a global not-for-profit advocacy association of brand owners and professionals dedicated to supporting trademarks and related intellectual property to foster consumer trust, economic growth, and innovation….International Trademark Association.

How does interrupt work?
An interrupt is a signal to the processor emitted by hardware or software indicating an event that needs immediate attention. Whenever an interrupt occurs, the controller completes the execution of the current instruction and starts the execution of an Interrupt Service Routine (ISR) or Interrupt Handler.
What are interrupts and its types?
TYPES OF INTERRUPTS Maskable Interrupt: The hardware interrupts which can be delayed when a much highest priority interrupt has occurred to the processor. Non Maskable Interrupt: The hardware which cannot be delayed and should process by the processor immediately.
What is use of kernel in OS?
The kernel is the essential center of a computer operating system (OS). It is the core that provides basic services for all other parts of the OS. It is the main layer between the OS and hardware, and it helps with process and memory management, file systems, device control and networking.
