ATMEGA48A-MMHR Overview


Due to its space-saving qualities, it is available in the 28-VFQFN Exposed Pad package. Mounted using Surface Mount. It comes in the package?of a Tape & Reel (TR). The device has a AVR core processor. During work, the temperature should remain at -40°C~85°C TA. In terms of its program memory type, it is FLASH. 23 I/Os can be found on it. Based on the ATMEGA48A base part number, it can be compared with other components. This device has terminals at QUAD. 28 terminationals are present. The AVR? ATmega series contains this electrical component. As a result of the 5V supply voltage, high efficiency is possible. The gadget has MICROCONTROLLER, RISC as its uPs/uCs/peripheral IC. It is constructed with 28 pins. The method of Surface Mount is used to mount it. The component is included in Microcontrollers. In the device, there is a memory capacity of 4kB which may be used to store programs and data. It is important to note that the maximum supply current is 12mA. Powered by a 2/5V source. It performs extremely well at a frequency of 20MHz. It appears that there are 3 timers/counters in use. There is also the property of ALSO OPERATES AT 2.7 V MINIMUM SUPPLY AT 10 MHZ AND 1.8 V MINIMUM SUPPLY AT 4 MHZ associated with it. Vsup should be kept above 4.5V for normal operation. Internal is the oscillator type it uses.
