How many pins does ATMega 8 have?
28 pins
The Atmega8 microcontroller consists of 28 pins where pins 9,10,14,15,16,17,18,19 are used for port B, Pins 23,24,25,26,27,28 and 1 are used for port C and pins 2,3,4,5,6,11,12 are used for port D.
What is ATmega8A?
The ATmega8 is a low-power CMOS 8-bit microcontroller based on the AVR RISC architecture. By executing powerful instructions in a single clock cycle, the ATmega8 achieves throughputs approaching 1 MIPS per MHz, allowing the system designer to optimize power consumption ver- sus processing speed.
How many ADC channels does ATmega8A?
The ATmega8A provides the following features: 8K bytes of In-System Programmable Flash with Read- While- Write capabilities, 512 bytes of EEPROM, 1K byte of SRAM, 23 general purpose I/O lines, 32 general purpose working registers, three flexible Timer/Counters with compare modes, internal and external interrupts, a …
How many PWM pins ATMega 8?
According to the image below, atmega8 has 3 PWM pins (9, 10 and 11) So, I created simple test for checking this pwm pins, I connected LED with resistor and I pushed code with analogWrite(9, 254); instruction and nothing happen.
What is the difference between ATmega8 and ATmega8A?
The ATmega8A is a functionally identical, drop-in replacement for the ATmega8. All devices are subject to the same qualification process and same set of production tests, but as the manufacturing process is not the same some electrical characteristics differ. ATmega8 and ATmega8A have separate datasheets.
What is microcontroller ATmega328?
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.
How many PWM outputs are there in ATmega 128?
6 PWM outputs
Using the ATmega PWM registers directly. The ATmega168P/328P chip has three PWM timers, controlling 6 PWM outputs. By manipulating the chip’s timer registers directly, you can obtain more control than the analogWrite function provides.
How many PWM outputs does the ATmega 16 have?
Atmega16 has four dedicated PWM pins.
What is the meaning of 328 in ATmega328?
ATmega328 Registers ATmega-328 has thirty-two (32) General Purpose (GP) registers. These all of the registers are part of Static Random Access Memory (SRAM).
How many timers does ATMEGA328P?
The Atmega328P has a total of three timer/counters named Timer/counter 0, Timer/counter 1, and Timer/counter 2. The first and last of these are both 8-bit timer/counters and have a maximum value of 255, while Timer/Counter 1 is 16 bits and its maximum is 65,535.
Which is the output port of ATmega 8?
Next, write-compile-build and burn the associated code to ATmega 8 as before. If everything is OK, the LED at pin 28 starts blinking for 6 times when you push the pushbutton switch (S2) for a while. In this setup Pin 28 is output port, and Pin 27 is an input port. Code will be explicated in the forthcoming part, so stay tuned!
Why is ATmega8 a 28 pin AVR microcontroller?
SCK (SPI Bus Serial Clock). This is the clock shared between this controller and other system for accurate data transfer. ATMEGA8 is a 28 pin AVR microcontroller. Although we have many similar microcontrollers, ATMEGA8 is popular because it is one of the cheapest microcontroller and provides many features in lesser pins.
How many I / O pins does ATmega8 have?
ATmega8 microcontroller has 23 programmable input/output (I/O) pins which can be used for interfacing with external world. It is possible to configure them as input or output by setting a particular register value through programming. This IC comes in 3 different packages, but we are using the popular 28-Pin PDIP package (Atmega8-16PU).
How to add a pushbutton switch to ATmega 8?
The work is very simple, because all you need is to add a pushbutton switch (at Pin 27) with the existing circuit. Next, write-compile-build and burn the associated code to ATmega 8 as before. If everything is OK, the LED at pin 28 starts blinking for 6 times when you push the pushbutton switch (S2) for a while.
