Atmega168

The ATMEGA168-20PU is a 8-bit high-performance, low-power AVR RISC-based Microcontroller Unit combines 16kB ISP flash memory, 1kB SRAM, 512B EEPROM, an 8-channel/10-bit A/D converter (TQFP and QFN/MLF) and debugWIRE for on-chip debugging.

How would you describe Atmel's ATMEGA168?

It is an 8-bit AVR microcontroller that comes with 32-pin interface and is mainly based on RISC CMOS technology. The Program memory is 16K, based on Flash, and incorporates read-write capabilities. The module comes with a wide temperature range from -40 to 85 ºC while operating voltage ranges from 1.8 to 5.5 V.

What is the difference between atmega168 and ATmega328?

The differences between the 328 and the 168 are pretty minor and you should see no differences except for having double the programming space! I also have a 40 pin 644P AVR chip that has double again the memory space of the 328 (64K).

Why it is called ATmega328p?

And the name of this Micro Controller is ATmega328p which is a product of ATmel. 32 - represents it's flash memory capacity that is 32KB. 8 - represents it's cpu type that is of 8 bit. p - simply denotes that it needs less power to work than it earlier version.

Can we use ATmega328 without Arduino?

You can use arduino board with the IC. Program the IC and then take it out and use it in your circuit. You will have to use 16MHZ Oscillator with capacitors. If you don't have arduino board, you can use other programmers like USBasp to program your Atmega328p .

Is ATmega328 Harvard architecture?

The ATmega328 is a single-chip microcontroller created by Atmel in the megaAVR family (later Microchip Technology acquired Atmel in 2016). It has a modified Harvard architecture 8-bit RISC processor core.

Can ATmega328 work without crystal?

Everybody runs the ATMega328 without a 16mhz crystal. Most people do use a 16MHz crystal.

Is ATmega328 a CPU?

Created by Atmel, the ATmega328P is a single-chip microcontroller based on an 8-bit RISC processor core.

Is Arduino and ATmega328 same?

It differs from the ATmega328 in that it is only available in a surface mount package, so can't be inserted into and removed from a socket on the Arduino. It also has more memory, more pins and more built-in hardware peripherals than the ATmega328.

What is difference between ATmega328 and ATmega328P?

DIFFERENCE BETWEEN ATMEGA328/328P Atmega328P just consumes lower power than Atmega328. Look up the numbers in the datasheet. This means that the 328P is manufactured in a finer process than the 328. Ex: 328 could be a 90nm process and 328P could be a 60nm process.

Is ATmega328 a AVR microcontroller?

The Atmel® picoPower® ATmega328/P is a low-power CMOS 8-bit microcontroller based on the AVR® enhanced RISC architecture.

Which software used for ATmega328P?

Download and install WinAVR from this page. WinAVR is a full suite with a compiler, programmer, debugger, and more! Use these for the USBTiny. It will include Programmer's Notepad, which is what we are going to use to program the ATMega, the AVRDude, and will burn fuses and act as a backup for programming the ATMega.

How much does ATmega328P cost?

Qty	Unit Price	Ext Price
25	$4.56760	$114.19
100	$4.13210	$413.21

Is Arduino Harvard or Von Neumann?

Basically, the processor of the Arduino board is based on the Harvard architecture, where the program code and program data use separate memory.

Is Harvard a RISC or CISC?

RISC (Reduced Instruction Set Computer) and CISC (Complex Instruction Set Computer) are the methodologies used in Harvard Architecture. In RISC microcontroller data is 8 bits, whereas instructions are 12 bits or 16 bits wide. Thus, everything is executed at a time resulting in increased performance.

Why is Harvard architecture not used?

A pure Harvard architecture suffers from the disadvantage that the mechanism must be provided to separate the load from the program to be executed into instruction memory and thus leaving any data to be operated upon into the data memory.

How is ATmega328 programmed?

Programming the ATmega328P Select the correct board in the Arduino IDE by going to Tools > Board and selecting "ATmega328 on a breadboard (8 MHz internal clock)" Select the correct programmer in the Arduino IDE by going to Tools > Programmer and selecting "Arduino as ISP"

How powerful is ATmega328P?

ATmega328P is a high performance yet low power consumption 8-bit AVR microcontroller that's able to achieve the most single clock cycle execution of 131 powerful instructions thanks to its advanced RISC architecture. It can commonly be found as a processor in Arduino boards such as Arduino Fio and Arduino Uno.

What is the difference between Arduino Uno and ATmega328?

In the UNO SMD (Surface Mounted Device) the microprocessor chip (ATmega328) is integrated and soldered onto the board; while in the standard UNO, the ATmega328 is DIP (Dual In-line Packaged), which means that the microprocessor chip can easily be removed and replace if necessary.

How much RAM does ATmega328P have?

RAM is limited to 2 Kbyte on an ATmega328, and often a scarce resource, especially since all strings also need to stored there (these get copied from flash on startup). EEPROM memory is the “configurable” memory available to a sketch.
