Question
why oscillators are used in micro controllers?
 Question Submitted By :: P.mgr
I also faced this Question!!     Rank Answer Posted By  
 
  Re: why oscillators are used in micro controllers?
Answer
# 1
as the oscillators chages the DC input to AC
output,Oscillators have the ability ot control the input
signals,that is why Oscillators are used in micro
controllers

  Re: why oscillators are used in micro controllers?
Answer
# 3
Oscillators are connected externaly with the
microcontroller to provides high frequency signal to the
oscillator circuit in the microcontroller. The oscillator
circuit provides the clock signal to the microcontroller.
that's it.

Answer
# 4
in MC all operations are processed upon trailing or leading
edges.because MC has several parts.Each parts are
constructed using Flip-Flop which needs clock for
triggering.

Answer
# 6
Oscillators are connected externaly with the
microcontroller to provides high frequency signal to the
oscillator circuit in the micro controller. The oscillator
circuit provides the clock signal to the micro controller.
usually "PIEZO CRYSTAL OSCILLATORS" are used in micro controllers.

Answer
# 7
its mainly used to control any process in micro second ,so
clock timer is very important without waiting for input
from any source.oscillator produces the output even without
any input signal and give high freq at initial input for
processor.

  Re: why oscillators are used in micro controllers?
Answer
# 8
every mc require the frequency, without freq it will not
work so here we can use the crytal where freq. is devived
by 2 e.g. 24/2= 12 so we got that 12 voltage for mc.... and
operate difernt parts of mc.......

  Re: why oscillators are used in micro controllers?
Answer
# 9
The main purpose of the oscillator in PICmicro
microcontrollers,
or almost any other microcontroller, is to
provide a reliable clock for the controller processes. At
the most basic level, the clock provides a timing interval
to account for circuit rise times and to allow data to
stabilize before that data is processed. This is a
"synchronous" process. The clock also provides an
opportunity for the programmer to perform time keeping
of several types. In the PICmicro, the clock also drives
hardware dedicated to timekeeping. The applications
may include keeping “real time”, or timing sensitive
processes
such as serial data communication. The accuracy
of these timing applications is dependent upon the
accuracy of the clock oscillator

Answer
# 10
Main purpose of oscillator is to generate pulse which is
used to synchronize all the circuit(ADC,TIMER etc) in
microcontroller. without pulse, the instructions will not
execute. tats it
