ATTINY40-MMHR Overview


For the purpose of saving space, it is available in the 20-VFQFN Exposed Pad package. A Surface Mount mounting method is used. A package of Tape & Reel (TR) contains it. AVR core processor is present on the device. Work should be performed at a temperature of -40°C~85°C TA. The type of memory it uses is FLASH. 18 I/Os can be found on it. To find comparable components, use the ATTINY40 base part number. The terminals of this device are located at QUAD. 20 terminations are present in it. It is a member of the AVR? ATtiny series of electrical components. Using the 5V supply voltage allows for high efficiency. MICROCONTROLLER, RISC is the uPs/uCs/Peripheral IC chip in this gadget. It is constructed with 20 pins. Based on the Surface Mount method, it is mounted. In the subcategory of Microcontrollers, this component is included. The devices have a maximum memory size of 4kB that can be used to store programs and data. It should be noted that 5mA represents the maximum supply current. Using a frequency of 12MHz, it is very efficient. The number of timers and counters is 2. The property of OPERATES AT 1.8 V MINIMUM SUPPLY AT 4 MHZ is also possessed by it. Normally, the supply voltage (Vsup) should remain above 4.5V. An oscillator type Internal is required for it to work.
