ATMEGA2561-16MI Product Details

ATMEGA2561-16MI Overview


The package has a 64-VFQFN Exposed Pad shape. With 54 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 256KB 128K 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 5V volt supply is provided by the Microcontroller chip. In addition to that, MCU chip has NO DMA channels. It is possible to find alternatives to the base part number ATMEGA2561 by using the part number search tool. There are a total of YES channels in the device. There are several CPUs that are embedded in the device, including the the AVR RISC CPU. The clock frequency is 16MHz. As an example, there is a feature called OPERATES AT 2.7V MINIMUM SUPPLY @ 8 MHZ to name only a few.
