ATMEGA48-20MMH Product Details

ATMEGA48-20MMH Overview


There is a 28-VFQFN Exposed Pad package available. The board has 23 I/Os. Using the Mounting Type Surface Mount, the MCU is mounted on PCB. A 8-Bit core is used in order to power the IC chip. The type of memory it uses for its program is FLASH. -40°C~85°C TA is the temperature range at which this Microcontroller operates. AVR® ATmega-series components are electrical components. In the case of this Microcontroller, the memory size of the program is 4KB 2K x 16. Powered by a AVR Core processor. Microcontroller's a MICROCONTROLLER, RISC uPs/uCs/Peripheral IC. IC Chip terminations are 28. As a result, this Microcontroller comes with a 8-bit size. Input voltage for the chip is 3V volts. A total of NO DMA channels are available. This IC part has a memory size of 4kB. There are a number of alternatives to the base part number ATMEGA48 that you can find. Performing well when operated at frequency 20MHz can be achieved. Using YES PWM channels, the device works. On the chip, there are 28 pins that can be accessed. It comes with 3 timers/counters that can be set up. The device is powered by the the AVR RISC CPU family that is embedded in it. It contains 1 serial input/output interfaces on the board. The part contains 2 interrupts external to the system. The total number of bits on a MCU chip is 3.
