ATMEGA328P-MMH Product Details

ATMEGA328P-MMH Overview


The package is 28-VFQFN Exposed Pad-shaped. There are 23 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~85°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 28 has 28 terminations. 8-bits are used for its size. IC Chip has 5V volt supply outputs. 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 ATMEGA328P, 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, 28 pins are accessible. In total, there are 3 timers/counters on the device. The pin count is 28. There is an embedded the AVR RISC CPU family inside the device, which makes it a powerful device. In addition to the above, there are other features such as ALSO OPERATES AT 2.7 V MINIMUM SUPPLY AT 10 MHZ AND 1.8 V MINIMUM SUPPLY AT 4 MHZ, to name but a few. The ADC channel count on this device totals up to 8 channels. In order for the device to function, it uses 6 PWM channels. 1 I2C channels are integrated by the part.
