ATMEGA325A-AU Product Details

ATMEGA325A-AU Overview


A 64-TQFP package is included. In total, it has 54 inputs and outputs. This Microcontroller is mounted using the Surface Mount mounting type. Powered by the 8-Bit core, it offers a wide range of capabilities. The type of memory that the program uses is FLASH. The temperature range of this Microcontroller is within the range of -40°C~85°C TA. AVR® ATmega series components belong to this electrical component. Its program memory size is 32KB 16K x 16. There is a AVR Core Processor inside MCU that provides this device with its power. MICROCONTROLLER, RISC uPs, uCs, and peripheral ICs make up the Microcontroller. Microcontroller is known that the chip has 64 terminations in total. The part works on a 8-bit basis. An output voltage of 5V volts is available for this Microcontroller chip. The Microcontroller chip has NO DMA channels. 32kB memory size belongs to the part. ATMEGA325A is the base part number that you can use to find alternatives. A good performance can be achieved at a frequency of 20MHz, as long as it is operated at a low power consumption. In order for the device to work with the motor, it utilizes the PWM channel YES. On the chip, there are 64 pins that are accessible. A total of 3 timers/counters are included in the package. A total of 64 pins are present. Devices based on the AVR RISC series of CPUs are embedded in the device. As a few examples, there are additional features like ALSO OPERATES AT 2.7 V MINIMUM SUPPLY AT 10 MHZ AND 1.8 V MINIMUM SUPPLY AT 4 MHZ that are available in the software. In total, there are 8 channels for the ADC on this board. A total of 4 PWM channels are used by the device. Devices like this use an 1-channel PWM controller.
