Pin 36 on the 8085 is RESET-IN/. There is a bar (/) to indicate that this is a negative logic (low=true) pin. Typically, you connect an RC network to pin 36 (1uF to GND, 75KOhm to Vcc, and small signal diode (1N914) across the capacitor with anode on pin 36) which creates a reset pulse at Vcc power on. The diode is used to force discharge on power off, ensuring a reset sequence when power glitches.

Main difference between 8085 and 8086?
The most significant difference between the Intel 8085 and 8086 microprocessors is that the 8085 is an 8-bit system and the 8086 is a 16-bit system. This difference allows the 8086 system to have a much larger set of operational instructions and can make calculations to more significant places. Note: the 8085 processor does have two 16-bit registers. The pointer and the program counter.
If the 8085 add 89h and 79h specify the contents of the accumulator?
In the 8085, if the accumulator starts as 00H, then adding 89H and 79H to it results in a value of 02H with CARRY set.
What are the factors and prime factors of 8085?
The factors of 8085 are 1, 3, 5, 7, 11, 15, 21, 33, 35, 49, 55, 77, 105, 147, 165, 231, 245, 385, 539, 735, 1155, 1617, 2695, and 8085 8085 = 3*5*7*7*11, so the prime factors are 3, 5, 7 and 11. 7 is used twice!
To find LCM of n numbers using 8085 programs?
sample program in sum of the series using the formula for s=n/2[2a+{n-1}d] in 8085
What is vss in 8085 pin digram?
Vss, also known as Gnd, is pin 20 on the 8085.
Why 8085 is a 40 pin ic?
The 8085 is a 40 pin ic because Intel designed it that way.
Which pin of 8086 is not compatible with 8085 for memory interfacing?
Pin 28 on the 8086/8088 is M/IO-, in minimum mode. The equivalent pin on the 8085 is IO/M-, and has opposite polarity.
What is advantage of trap pin ion 8085?
TRAP is a non maskable interrupt pin in 8085.....it has the highest priority out of all the interrupts...it is used in emergency n critical states..ex.during power loss etc.
What is meant by trap in 8085?
TRAP is a single pin interrupt that is non-maskable in the 8085. It is intended for notification of serious system problems and/or as an aid to a hardware assisted debugger.
What is the function of interrupt acknowledge pin in 8085 micro processor?
The INTA- (Interrupt Acknowledge) pin on the 8085 is an acknowledge of the INTR (Interrupt Request). It has the same timing as RD-, and external hardware is expected to provide an opcode, usually a CALL or an RST instruction, in response to INTA-.
How many pints in a pin?
There are 2 pints in a pin.
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 the function of READY pin of 8085?
The READY pin on the 8085 microprocessor is used to delay the completion of a bus transfer cycle. It is sampled by the 8085 at the falling edge of clock following ALE. If it is high, the cycle completes. If it is low, the cycle is extended by one clock, with all lines held steady - then it is sampled again at each of the next falling edges of clock until it is high. The purpose of READY is to allow (usually) memory devices to operate at a slower speed than the 8085.

How can you trap mask in 8085 microprocessor?
The TRAP instruction in the 8085 is NONMASKABLE, which means it cannot be masked, i.e. it cannot be disabled. The only way to mask or disable TRAP is with external hardware, such as an I/O pin and an AND gate.
What was the reason behind limit of maximum pin in microprocessor 8085?
There is no maximum pin in the 8085. In the 8086/8088, however, there is a min/max pin, called MN/MX-, that is used to configure whether certain bus control signals are provided by the 8086/8088, or by the 8288 bus controller. In the latter case, this frees up several pins for other, more sophisticated, i.e. maximum mode, uses.
