ATTINY44A-MMH Overview


To save space, it is included in the 20-VFQFN Exposed Pad package. Surface Mount is used for mounting. This item can be found in package Tray. The device has a AVR core processor. Maintain a temperature of -40°C~85°C TA while working. It has a type of program memory of FLASH. A total of 12 I/Os are present. Based on the ATTINY44A base part number, it can be compared with other components. The position of the device is QUAD at terminal. A 20 termination is contained within it. An electrical component such as this is included in the series AVR? ATtiny. By using a 5V voltage supply, high efficiency is possible. This gadget has MICROCONTROLLER, RISC as its uPs/uCs/Peripheral IC. The structure is constructed from 20 pins. Mounting is performed in accordance with Surface Mount. It is one of the components included in Microcontrollers. In order to store data and programs, the devices have a memory size of 4kB. Supply current cannot exceed 7mA. Using a frequency of 20MHz, it is very efficient. 2 counters/timers are currently active. Normally, the supply voltage (Vsup) should remain above 4.5V. Using an oscillator type Internal, it operates.
