ATMEGA48-20MMH Overview


As a result, it is available in the 28-VFQFN Exposed Pad package. A Surface Mount mounting method is used. This item can be found in package Tray. A AVR core processor powers the device. It is important to keep the temperature at -40°C~85°C TA while working. Its type of program memory is FLASH. The device has 23 I/Os. To find comparable components, use the ATMEGA48 base part number. QUAD is the position of its terminals on the board. Currently, it consists of 28 terminationals. The AVR? ATmega series contains this electrical component. This is due to the fact that the supply voltage is 3V, resulting in high efficiency. The gadget has MICROCONTROLLER, RISC as its uPs/uCs/peripheral IC. It is constructed with 28 pins. According to Surface Mount, it is mounted. This component is a part of Microcontrollers. Data and programs can be stored on the devices with a memory size of 4kB. It should be noted that 12mA represents the maximum supply current. Using a frequency of 20MHz, it is very efficient. A total of 3 timers/counters are present. For normal operation, the supply voltage (Vsup) should be kept above 2.7V. Using a Internal oscillator type, it works well.
