ATMEGA649-16MU Product Details

ATMEGA649-16MU Overview


Packaged in a 64-VFQFN Exposed Pad format. A total of 53 I/Os are on the Microcontroller. Surface Mount is the mounting type of the Microcontroller that is attached to the panel. This Microcontroller is based on a core called 8-Bit. The type of its program memory is FLASH. In this Microcontroller, temperature is controlled within the range -40°C~85°C TA. A AVR® ATmega series electrical component is used in this application. This program has a program memory of 64KB 32K x 16 bytes, which is the size of the program. With a AVR Core Processor, Microcontroller is fast and efficient. ICs for MICROCONTROLLER, RISC uPs/uCs/peripheral parts. There are 64 terminations on the IC chip, which means there are 64 terminations on the integrated circuit chip. In addition, MCU chip comes with a 8-bit size. Microcontroller chip has outputs of 5V volts. The system has NO channels for DMA communication. There is 64kB memory size assigned to the part. Alternatives can be found by searching through the base part number ATMEGA649 to find them. At a frequency of 16MHz, Microcontroller can operate efficiently. This MCU Chip uses YES PWM channels to operate. Chips have 64 pins. There are 3 timers/counters in this device. The AVR RISC CPU family is embedded in the device, so it can handle a wide range of operations. In the 54 Programmable I/O section, it can be programmed in many different ways. As an example, one of the additional features that you can use is ALSO OPERATES AT 2.7V SUPPLY AT 8 MHZ. It consists of 8 Channel channels in total for the ADC.
