ATMEGA645V-8AU Product Details

ATMEGA645V-8AU Overview


64-TQFP-packages are available. There are 54 I/O ports on this device. Device mounting type Surface Mount is the type of mounting that the Microcontroller uses. There is a 8-Bit core at the core of this MCU. There is a type of program memory called FLASH in the Microcontroller. There is a temperature range of -40°C~85°C TA for this Microcontroller. An electrical component of this type belongs to the AVR® ATmega series. This program memory has a size of 64KB 32K x 16, which indicates what the size of the program memory is. AVR Core processors are used in MCU. Devices of this type belong to the MICROCONTROLLER, RISC power supply/socket/peripheral ICs category. This chip has a total of 64 terminations on MCU chip. You get a 8-bit size. This Microcontroller chip is powered by 3V volts. There are NO DMA channels on this Microcontroller chip. The part has a memory size of 64kB. The base part number ATMEGA645 provides alternatives. This device is extremely efficient when operated at a frequency of 8MHz. Using the PWM channel YES, the device works with the motor. In this chip, 64 pins can be accessed. Using the timer/counter system, it has 3 timers/counters. In addition to this, the device is embedded with the the AVR RISC CPU family. This device has 54 programmable input and output channels. Some of these features include ALSO OPERATES AT 1.8 V MINIMUM SUPPLY AT 4 MHZ, for example, as one example. In total, it has 8 ADC channels for the measurement of signals. As far as the PWM channel count is concerned, the device makes use of 4 channels. As part of the design, the part has been designed to feature 1 channels for I2C communication.
