PICs are faster, more reliable high noise immunity and code-effecient than s. The basic difference between the both is that Pic got an internal memory while dont hav internal memory.. PIC is more reliable.. Intel's and Motorola's microcontrollers have over hundred instructions All of these instructions are executed in one cycle except for jump and branch instructions.
According to what its maker says, PIC16F84 usually reaches results of in code compression and in speed in relation to other 8-bit microcontrollers in its class. PaulHolland Advanced Member level 2. Even the philips databooks call them microcontrollers.. Pic is a micro controller while is a micro processor.. Click to expand It was extremely popular in the s and early s, but today it has largely been superseded by a vast range of enhanced devices with compatible processor cores that are manufactured by more than 20 independent manufacturers including Atmel, Maxim IC via its Dallas Semiconductor subsidiary , Philips, Winbond, and Silicon Laboratories.
Intel's original family was developed using NMOS technology, but later versions, identified by a letter "C" in their name, e.
Can access 8 bit data in one operation. Hence called 8-bit microprocessor. Can access memory locations i. A particularly useful feature of the core is the inclusion of a boolean processing engine which allows bit-level boolean logic operations to be carried out directly and efficiently on internal registers and RAM. This feature helped to cement the 's popularity in industrial control applications.
Another valued feature is that it has four separate register sets, which can be used to greatly reduce interrupt latency compared to the more common method of storing interrupt context on a stack. The UART can be configured to use a 9th data bit that can provide addressable communications in an RS multi-point communications environment. The original core ran at 12 clock cycles per machine cycle, with most instructions executing in one or two machine cycles.
With a 12 MHz clock frequency, the could thus execute 1 million one-cycle instructions per second or , two-cycle instructions per second. Enhanced cores are now commonly used which run at six, four, two, or even one clock per machine cycle, and have clock frequencies of up to MHz, and are thus capable of an even greater number of instructions per second.
Several C compilers are available for the , most of which feature extensions that allow the programmer to specify where each variable should be stored in its six types of memory, and provide access to specific hardware features such as the multiple register banks and bit manipulation instructions.
The 's predecessor, the , was used in the keyboard of the first IBM PC, where it converted keypresses into the serial data stream which is sent to the main unit of the computer. The and derivatives are still used today for basic model keyboards. Thank you for reading. Skip to content. Difference Between Electronics Embedded System.

What Is Microcontroller? Applications of microcontrollers: Home appliances like Microwave Oven, Washing machines, etc. Light sensing and controlling devices like audio systems. Temperature sensing and control devices. Fire detection and safety devices such as home security systems. Other devices like calculator, ATM machine, etc. It must have the ability to control different types of software. It is compatible with the sleep mode of operation.
PIC is not a microcontroller, but is an extensive family of microcontrollers designed and manufactured by Microchip, Inc. Both are quite popular, and there are many other microcontrollers available. The microcontrollers are very limited. The Pic Controller has many advantages over a The main advantage is the editing capabilities. Another advantage is the high resolution.
PIC's are a series of microcontrollers made by Microchip Inc. See the web link for Microchip's website. In general, personal preference and experience is what it comes down to. DSP's are mainly based on Harvard architecture to perform task faster with hard wired instructions as compared to Microcontrollers which are mainly available with von neumann architecture some microcontrollers like PIC is an exception.
The DSP can compute the numerical parts of your application faster than the microcontroller can. Because that's what it's designed to do. You might also find that DSPs have more of the "right sort" of integrated peripherals, compared to microcontrollers. Answer It is both 8 bit processors in a 40 pin package but it is not pin compatible, it have almost the same functions but it is very difficult to compare the two because it is not the same family. C is compiled and runs on the metal and Java is interpreted and runs in a sandbox.
Completely different. The answer to the question is yes, you can. The difference is base on the requirement of their0 application. I'm more of a PIC guy, but as far as i understood it, yes instruction set is the same for all legacy devices. That includes 89s The light sensors video or image sensor and by reading this data the microcontroller will process the input data and control some output operations like sending SMS alerts to the user through GSM or controlling the lights and fans by using the relays or generating some alarms or displaying some values on the LCD display.
The on microcontroller is produced by many manufacturers some of them are Atmel, Intel, Philips which is an XP, sharp, Texas Instruments, maximum Dallas. Here is a general architecture of microcontroller. So although the microcontrollers are very popular and they are good but they are more advanced microcontrollers available from Atmel AVR.
So our first microcontroller microcontrollers has one serial communication channel that is USART for serial communication of data. Transmitter as communication is not synchronous the receiver and transmitter operate at same speed or same baud rate and the data byte is framed between these start and stop bits to indicate the start of data byte and end of data byte and you cannot connect more than two channels on the UART bus if we want a secure transmission.
The has four important ports. Port 0, Port 1, Port 2 and Port 3. These ports allow the microcontroller to connect with the outside world. Each port has 8 pins thus the four ports joint comprise 32 pins. All ports are bidirectional each port has a latch and driver.
AVR is a risk microcontroller based on modified Howard architecture. So it was developed by Atmel in and it is better than the microcontroller in many aspects. There are two different resistors so it makes the operation easy and also most instructions in the AVR microcontrollers take just one or two clock cycles which makes the AVR microcontrollers fast among the present 8-bit microcontrollers has some features of the AVR microcontrollers that it has a internal power on reset circuit internal calibrated oscillators on chip Ram flash EEPROM or non-volatile memory and some resistors on chip Analog to digital converter comparator compatible with the SPI interface, 2-wire interface and compatible, USART, JTAG and CAN.
It is the architecture of the Atmel AVR. The AVR has an orthogonal instruction set orthogonal means that all the instructions can use all the addressing modes we can apply any operation on any resistor unit using any addressing mode.
