Draw a schemetic to demultiplex bus ad0-ad7 using any octal latch in 8085 microprocessor?
The 8085 microprocessor is used IC 74LS373 to latch the address of 8085. Basically latch is consists of 8 flip flops. Generally we used D-flip flops (Delay).The clock of these flip flops are connected together and available as a output pin called enable.Working : The address will appear on AD0 AD7 lines. The ALE will go high and forcingEnable = 1. This will make latch enable and ready to work. Before address disappears ALE = 0. This will make latch disable. AD0 - AD7 will now be used as data bus.Hence, AD0 - AD7 (low order) address bus of the 8085 microprocessor is multiplexed (time-shared) with the data bus. The buses need to be demultiplexed.
A positive going pulse which is always generated when 8085 MPU begins the machine cycle?
ALE Address Latch Enable
Can you use a buffer in place of latch and vice versa in 8085 interfacing?
A buffer is a signal booster that allows you to drive lines with a larger fan-in requirement. A latch is a device that remembers the state of an input line after some point in time. The two are not interchangable.
What is latch in 8085?
· A latch remembers the last state it was told to with another latching signal · A buffer merely strengthens a signal so that it can be fanned out with integrity or drive a heftier device. Any amplifier is a buffer. It outputs a state only as long as the state persists on its input(s).
Why the name 8085 Why the name 8085 for microprocessor?
8085 is a microprocessor designed by Intel
What is the need of ale signal in 8085?
The ALE signal on the 8085 is Address Latch Enable. When ALE is true, the data bus contains the low order address information for the current bus cycle. External hardware, i.e. latches, are expected to follow the data bus when ALE is true. At the point where ALE goes false, at approximately the rising edge of CLK, the latches are expected to latch and hold the data bus, presenting it to the outside world as the low order address bus.
Why the 16 bit 8085 microprocessor is not possible?
The 8085 was replaced with the 8086/8088. As such, there is no 16 bit version of the 8085.
Difference between 8080 and 8085?
The 8085 has a single +5V power supplyThe 8085 has a multiplexed low order address busThe 8085 has extra single pin interrupts, TRAP, RST7.5, RST6.5, and RST5.5The 8085 has serial I/O pins SID and SODThe 8085 has maskable interrupts and the RIM/SIM instructionThe 8085 includes the functionality of the 8224 clock genereator and 8228 system controllerThe 8085 added several 16 bit operations
What is themeaning of pipe lines for 8085 microprocessor?
The 8085 is not pipelined.
When 8085 processor was invented?
The 8085 was introduced by Intel in 1977.
What do '8085' in 8085 Microprocessor signify?
The '8085' in the 8085 microprocessor is the designation given to the microprocessor by Intel. The '5' means it is a single power supply (5 volt) version of the 8080, with enhancements.
