ATMEGA16U2-AU Product Details

ATMEGA16U2-AU Overview


The package has a 32-TQFP shape. With 22 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 16KB 8K 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 16kB. It is possible to find alternatives to the base part number ATMEGA16U2 by using the part number search tool. An effective performance can be achieved at a frequency of 16MHz. 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 2 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 8 MHZ to name only a few. A total of 5 PWM channels are being used by the device.
