Microchip ATMEGA328PB-AN, 8bit 8 bit CPU Microcontroller, ATmega, 20MHz, 32 kB Flash, 32-Pin TQFP. Here are few of its features: Atmega328 has 28 pins in total. It has 3 Ports in total which are named as Port B, Port C and Port D.
Which ports of ATmega328p have analog pins?
The Atmega328 has 28 pins. It has 14 digital I/O pins, of which 6 can be used as PWM outputs and 6 analog input pins. These I/O pins account for 20 of the pins….Atmega328 Pinout.
| Pin Number | Description | Function |
|---|---|---|
| 18 | PB4 | Digital Pin |
| 19 | PB5 | Digital Pin |
| 20 | AVCC | Positive voltage for ADC (power) |
| 21 | AREF | Reference Voltage |
How do I connect my atmega to my computer?
Interface the Atmega 16/32 with the PC
- connect pin no 3 (Rx) of serial port to Rx in of the MAX 232 IC (pin no 13)
- connect pin no 14 (RxD) of Atmega to Rx out of MAX 232 IC (pin no 12)
- connect pin no 15 (TxD) of Atmega to Tx in of MAX 232 IC (pin no 11)
- Do other necessary connections like ground and Vcc.

What is the bus width for AVR microcontroller?
AVR micro-controller bus width is 8/32-bit. PIC micro-controller bus width is 8/16/32-bit.
What kind of serial communication does ATmega328P support?
Universal Synchronous and Asynchronous serial Receiver and Transmitter (USART) is a configurable peripheral of ATmega328p which supports both Synchronous (SPI) and asynchronous (Serial) communication protocols. In our case we will be dealing only with asynchronous communication.
Which is universal asynchronous receiver transmitter in ATmega 328?
The ATMEGA 328 has one Universal Asynchronous Receiver Transmitter. The pinout of the ATMEGA 328 is as shown in the following image: It is important to note that almost all pins of the ATMEGA 328 microcontroller except GND, VCC and AREF are multiplexed pins.
How many pins are in an Arduino ATmega328 microcontroller?
The ATMEGA328 in the Arduino UNO microcontroller development board is as shown in the following figure: ATMEGA 328 microcontroller is an eight bit microcontroller based on the RISC (Reduced Instruction Set Computing) architecture. It has total 28 pins out of which some are GPIO (General Purpose Input / Output) pins and some are power pins.
How does ATmega328P work with ucsr0a Register?
The code for receiving the characters is almost same as the transmission program,Here we are enabling the receiver instead of the transmitter. The Atmega328p checks the status of the RXC0 bit in UCSR0A register continuously and waits for any data to be received.
