ATMEGA328-MMHR Overview
For space savings, it is available in the 28-VFQFN Exposed Pad package. The way of Surface Mount is used to mount it. It is available in the Tape & Reel (TR) package. A AVR core processor powers the device. The temperature should be kept at -40°C~85°C TA while working. Memory type FLASH is used for program memory. 23 I/Os are present on the device. A comparable component can be found by using the base part number ATMEGA328. This device has terminals at QUAD. This circuit consists of 28 terminationals. This electrical component is part of the AVR? ATmega series. The supply voltage of 5V allows for high efficiency. In data storage, FLASH, OTP is used as the memory type. In this gadget, MICROCONTROLLER, RISC is the device's uPs/uCs/Peripheral IC. It is constructed with 28 pins. A method of mounting is used, which is Surface Mount. It is one of the components included in Microcontrollers. Using the devices' 768B memory size, you can store programs and data. Supply current is maximum at 12mA. A 2/5V source is used for powering it. When working at a frequency of 4MHz it is able to achieve excellent efficiency. 3 timer/counters are present. For normal operation, the supply voltage (Vsup) should be kept above 4.5V. An oscillator type Internal is required for it to work.
