Microcontroller is a microprocessor system
SET is contained inside a chip. Contains components
Supporting microprocessor systems, memory and interface providers
(Interface) Input output controller, the difference with
The microprocessor usually contains only CPUs (except
SandybridgeCPU).
Significant difference between Microprocessor and
Microcontroller is, Microprocessor is a CPU (Central
Processing Unit) without memory and I / O support, meanwhile
Microcontroller consists of CPU, Memory, certain I / O and units
Supporters, such as Analogto Digital Converter (ADC)
Already integrated in the microcontroller.
This system can receive input signal, process it and
Provide output signal in accordance with the program in content to
Inside.
The input signal of the microcontroller is derived from the sensor which is
Information from the environment (discrete) while the output signal
Addressed to the actuator (an electronic circuit for
Move or control a mechanism or system)
Then give effect to the environment.
Easily the microcontroller can be analogized as the brain of
A device / product that is programmed to be capable
Interact with the surrounding environment in accordance with the command
Programming. The microcontroller system is often referred to as
Embeddedsystem is the embedded system controller on
A product.
Embedded System can not Stand Alone
Physically the workings of a microcontroller can be explained
As read instruction cycles are stored inside
Memory. The microcontroller will determine the address of the memory
The program to be read, and do the reading process
Data on its memory. Then the data is read
Interpreted as commands called programs
Counter.
The microcontroller needs a clock oscillator to trigger the CPU
Working on one instruction to the next instruction on the fly
Sequential.Each small step of microcontroller operation
It requires one or more clock cycles for
Run it.
There are several different types of memory encountered within
Microcontroller, ROM (ReadOnly Memory) and RAM (Random
Access Memory). ROM used as Storage media
Program whereas in modern electronic Circuit Often
Using EPROM type (Erasable Programmable Read Only
Memory) and EEPROM (Electrical Erasable Programmable Read
Only Memory). CPU, memory, clock oscillator, and I / O are in
One integrated circuit. If some elements are removed, then
This system can not work.
In this note I will discuss how the application
A micro controller inside a circuit board especially on
Laptop motherboard.
Unlike the simple Embedded controller
, Micro controller on sircuit Laptop Motherboard is more complex
Where the Embedded system has an external rom called
With a BIOS IC. Though separate they really are
Parts that can not be separated.
EC bios the task of controlling Power management and others
In accordance with the programming commands that are already set
Based on interfaces I.O available. Differences arrangement
Circuit with programming will cause no system
Function.
Storage capacity on ROM is also much larger so
More detailed and complex programming can be done.
Almost a whole System switching on a motherboard Laptop
Arranged by this system, even micro controller in this system
Can do 5 stages switching which time is not
At the same time or the term is better known as Sleep State.
Micro controller can accept ADP + input as VALW command
Standby on the main Power Line in the circuit, the input signal is set
Based on programming commands so that if signal
Input (adapter current detector) recorded according to range
Programming then EC will allow ADP + to go inside
Circuit and when the input detects an excessive voltage
Then the system will push the analog ground to
Blocking ADP + from entering into circuit and activating
OVP (over voltage protection)
Embedded systems also manage based on input signal when
Must be ordered to do charging system on battery
Laptop, usually this signal is called BAT_IN and active when
Battery installed, this detection will give the command
To perform charging by sending a signal
CHG_Enable on Charger IC.
So many Embedded systems are involved in the motherboard
Laptop, they set almost the entire input output
Communication interface inside sircuit.
Beginning with a switching system in which the EC receives a signal
EC_ON to enable the Embedded controller and enable
VS signal (State enable) then sends signal gate driver
To enable Power state based on the sequence it has
Programmed.
Embedded systems also receive sensor detection inputs
Heat on and off Power System if temperature exceeds
Specified limits and more setting settings
Which I may discuss in a closed session.
