ATMEGA329P-20MU Product Details

ATMEGA329P-20MU Overview


Packaged in a 64-VFQFN Exposed Pad format. A total of 54 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 32KB 16K 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 32kB memory size assigned to the part. Alternatives can be found by searching through the base part number ATMEGA329P to find them. At a frequency of 20MHz, 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. As an example, one of the additional features that you can use is ALSO OPERATES AT 2.7 V MINIMUM SUPPLY AT 10 MHZ.
