ATMEGA328-AUR Product Details

ATMEGA328-AUR Overview


The package has a 32-TQFP shape. With 23 I/Os, it's pretty good. The Microcontroller's mounting type is Surface Mount and this IC chip has the following features. As the name implies, this Microcontroller is based on the 8-Bit core. As far as its program memory type is concerned, it is FLASH. Temperatures within -40°C~85°C TA range are measured by this Microcontroller. The AVR® ATmega series is comprised of this electrical component. The electronic part has a program memory size of 32KB 16K x 16. There's a AVR Core Processor inside. The IC chip fits into the MICROCONTROLLER, RISC uPs/uCs/Peripheral ICs category. There are 32 terminations on the IC chip. 8-bits are the size of the data that comes with MCU. A 5V volt supply is provided by the Microcontroller chip. In addition to that, MCU chip has NO DMA channels. Its memory size is 8kB. It is possible to find alternatives to the base part number ATMEGA328 by using the part number search tool. An effective performance can be achieved at a frequency of 20MHz. There are a total of YES channels in the device. It is possible to access the 32 pins on the chip. In total, it has 3 timers and counters in it. A total of 32 pins are included in the package. There are several CPUs that are embedded in the device, including the the AVR RISC CPU. As an example, there is a feature called ALSO OPERATES AT 2.7 V MINIMUM SUPPLY AT 10 MHZ AND 1.8 V MINIMUM SUPPLY AT 4 MHZ to name only a few. As far as UART channels are concerned, it has 1. The ADC channels on this device total 8 Channel in number. The part has been designed to incorporate 1 I2C channels.
