ATmega328 Microcontroller Chip - DIP

Product ID: 108
Atmega328 microcontroller chip


The ATmega328 is a micro-controller by Atmel. Its a high performance, low power 8-bit AVR RISC-based microcontroller. It has 32KB ISP flash memory with read-while-write capabilities, has 1KB EEPROM, 2KB SRAM . There are 23 general purpose I/O lines and 32 general purpose working registers which gives it power to controller large number of peripheral. Apart from that there are three flexible timer/counters with compare modes, internal and external interrupts. In order to communicate with external circuitry there is a serial programmable USART, a byte-oriented 2-wire serial interface and a SPI serial port. There are in total 6-channels of 10-bit A/D converters. A programmable watchdog timer with internal oscillator is also present. and five software selectable power saving modes.

All of the above features with a RISC architecture makes this microcontroller as one of the best chips to get started with doing projects in electronics.
