ATMEGA48A-MMH Overview
A space-saving advantage is that it is included in the 28-VFQFN Exposed Pad package. Surface Mount is the way to mount it. In the package Tray, it is included. It is equipped with a AVR core processor. It is important to keep the temperature at -40°C~85°C TA while working. FLASH is its program memory type. 23 I/Os have been provided by the device. A component with the same part number as ATMEGA48A can be compared to other similar components. At QUAD, its terminals are located. As far as terminations are concerned, there are 28 terminations present. Part of the AVR? ATmega series, this electrical component is used in a variety of applications. By using a 5V voltage supply, high efficiency is possible. In this gadget, MICROCONTROLLER, RISC is the device's uPs/uCs/Peripheral IC. A number of 28 pins are used to construct it. During the mounting process, the device is mounted based on the Surface Mount method. In the subcategory of Microcontrollers, this component is included. The devices have a memory size of 4kB that can be used to store programs and data. When working at a frequency of 20MHz it is able to achieve excellent efficiency. A total of 3 timers/counters are present. During normal operation, the supply voltage (Vsup) should be kept above 4.5V. It works with an oscillator type Internal.
