ATMEGA644A-MU Product Details
ATMEGA644A-MU Overview
There is a 44-VFQFN Exposed Pad package available. The board has 32 I/Os. Using the Mounting Type Surface Mount, the MCU is mounted on PCB. A 8-Bit core is used in order to power the IC chip. The type of memory it uses for its program is FLASH. -40°C~85°C TA is the temperature range at which this Microcontroller operates. AVR® ATmega-series components are electrical components. In the case of this Microcontroller, the memory size of the program is 64KB 32K x 16. Powered by a AVR Core processor. Microcontroller's a MICROCONTROLLER, RISC uPs/uCs/Peripheral IC. IC Chip terminations are 44. As a result, this Microcontroller comes with a 8-bit size. A total of NO DMA channels are available. This IC part has a memory size of 64kB. There are a number of alternatives to the base part number ATMEGA644A that you can find. Performing well when operated at frequency 20MHz can be achieved. Using YES PWM channels, the device works. On the chip, there are 44 pins that can be accessed. It comes with 3 Timer timers/counters that can be set up. The pins counted are 44. The device is powered by the the AVR RISC CPU family that is embedded in it. FLASH memory is one of the features of this equipment. The CPU is based on AVR cores. There are 32 Programmable I/Os on this computer. In addition, it has 8 UART channels to choose from. The device has a total of 8 ADC channels in total. There are 6 PWM channels used by the device in total. A total of 1 I2C channels have been integrated into the part. It contains 2 serial input/output interfaces on the board. The part contains 3 interrupts external to the system. The total number of bits on a MCU chip is 3.
