ATMEGA48-20MMU Overview


To save space, it is included in the 28-VFQFN Exposed Pad package. The way of Surface Mount is used to mount it. Package Tray contains it. It is equipped with a AVR core processor. Maintain a temperature of -40°C~85°C TA while working. The type of memory it uses is FLASH. There are 23 I/Os on it. Other components that are comparable to it have the base part number ATMEGA48. This device has terminals at QUAD. 28 terminations are present in it. Part of the AVR? ATmega series, this electrical component is used in a variety of applications. By using a 3V voltage supply, high efficiency is possible. UPs/UCS/Peripheral ICs of this gadget are MICROCONTROLLER, RISC in order to monitor their performance. The structure is constructed from 28 pins. According to Surface Mount, it is mounted. In the subcategory of Microcontrollers, this component is included. In order to store data and programs, the devices have a memory size of 4kB. The maximum supply current is set at 12mA. It is highly efficient when it works at a frequency of 20MHz. 3 timers/counters are in use. In order to maintain normal operation, the supply voltage (Vsup) should be maintained above 2.7V. Using an oscillator type of Internal, it works.
