ATMEGA1281-16AUR Product Details

ATMEGA1281-16AUR Overview


In a 64-TQFP package, the MCU is available. 54 I/Os are available. The Microcontroller has a mounting type of Surface Mount, which indicates that it is mounted conveniently. The 8-Bit core is the core of the MCU. There is a FLASH type of memory for its program. There is a temperature range of -40°C~85°C TA that is operated by this Microcontroller. AVR® ATmega series components make up this electrical component. 128KB 64K x 16 is the size of its program memory. A AVR Core processor is used to power the device. This device falls under the MICROCONTROLLER, RISC uPs/uCs/Peripheral ICs category. 64 is the number of terminations on the IC chip that are present. This part works in a 8-bit manner. There is a 5V volt supply output on the chip. DMA channels number NO. 4kB is the memory size of the part. The base part number ATMEGA1281 can be used to find alternatives. The efficiency of this device can be improved when operating at a frequency of 16MHz. The device works in YES PWM channels. Located on the chip are 64 pins. The clock has 6 timers or counters on it. In this device, there is a AVR RISC CPU embedded within it. It has built-in FLASH, OTP memory. There is an integrated AVR core architecture in it. It programs in 54 Programmable I/O. I would like to mention a few additional features such as ALSO OPERATES AT 2.7V MINIMUM SUPPLY AT 8 MHZ in order to name a few.
