ATMEGA645V-8AUR Product Details

ATMEGA645V-8AUR Overview


The package has a 64-TQFP shape. With 53 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 64KB 32K x 16. There's a AVR Core Processor inside. The IC chip fits into the MICROCONTROLLER, RISC uPs/uCs/Peripheral ICs category. There are 64 terminations on the IC chip. 8-bits are the size of the data that comes with MCU. A 3V volt supply is provided by the Microcontroller chip. In addition to that, MCU chip has NO DMA channels. Its memory size is 64kB. It is possible to find alternatives to the base part number ATMEGA645 by using the part number search tool. An effective performance can be achieved at a frequency of 8MHz. There are a total of YES channels in the device. It is possible to access the 64 pins on the chip. In total, it has 3 timers and counters in it. There are several CPUs that are embedded in the device, including the the AVR RISC CPU. As far as the programmability is concerned, it has 54 Programmable I/Os. As an example, there is a feature called ALSO OPERATES AT 1.8 V MINIMUM SUPPLY AT 4 MHZ to name only a few.
