ATMEGA329P-20AN Product Details

ATMEGA329P-20AN Overview


The package is 64-TQFP-shaped. There are 54 I/Os. In the case of the IC chip, the type of mounting is Surface Mount. Microcontroller is based on the 8-Bit core architecture. The type of program memory it uses is FLASH. Temperatures in the range of -40°C~105°C TA are operated by this Microcontroller. It is part of the AVR® ATmega series of electrical components. Having a size of 32KB 16K x 16, Microcontroller has a program memory of X bytes. A AVR Core Processor is at the core of this Microcontroller. This device belongs to the MICROCONTROLLER, RISC uPs/uCs/Peripheral ICs category. IC Chip 64 has 64 terminations. 8-bits are used for its size. With NO DMA channels, Microcontroller chip can handle large data transfers. 32kB is the size of the memory in the IC part. Using the base part number ATMEGA329P, you will be able to find alternatives for the part. Using a 20MHz frequency, this electronic part can perform efficiently. Devices work in YES PWM channels. On the chip, 64 pins are accessible. There is an embedded the AVR RISC CPU family inside the device, which makes it a powerful device.
