As a result, it is available in the 20-WFQFN Exposed Pad package. A Surface Mount mounting method is used. Package Tape & Reel (TR) contains it. Device with AVR core processor issupported. Maintain a temperature of -40°C~85°C TA while working. FLASH has been assigned to it as a program memory. There are 12 I/Os on it. Based on its base part number of ATTINY44, other similarly-sized components can be found. QUAD is the location of its terminals. A 20 termination is contained within it. It is a member of the AVR? ATtiny series of electrical components. Because of the 3V voltage of the supply, high efficiency can be achieved. MICROCONTROLLER, RISC is this gadget's uPs/uC/peripheral IC. 20 pins are used to construct it. A method of mounting is used, which is Surface Mount. Subcategory Microcontrollers includes this component. The devices have a memory size of 4kB that can be used to store programs and data. There is a maximum current supply of 9mA. It is highly efficient when it works at a frequency of 10MHz. A total of 2 timers/counters are present. In addition, it is also capable of having the property OPERATES AT 1.8 V MINIMUM SUPPLY AT 4 MHZ. An oscillator of type Internal is used.
