                                                ATTINY261A-PU Overview
Due to the benefits of saving space, it is available in the 20-DIP (0.300, 7.62mm) package. A Through Hole mounting method is used. Package Tube contains it. It is equipped with a AVR core processor. In order to work effectively, the temperature should be kept at -40°C~85°C TA. It has a type of program memory of FLASH. There are 16 I/Os on it, which makes it a very simple device. It has a part number of ATTINY261A that can be used to locate similar components. At DUAL, it has its terminals. It has 20 terminationals. It is a member of the AVR? ATtiny series of electrical components. As a result of the 5V supply voltage, high efficiency is possible. UPs/UCS/Peripheral ICs of this gadget are MICROCONTROLLER, RISC in order to monitor their performance. A total of 20 pins are used in its construction. A method of mounting is used, which is Through Hole. In the subcategory of Microcontrollers, this component is included. In order to store data and programs, the devices have a memory size of 2kB. There is a maximum current supply of 7mA. At a frequency of 20MHz, it exhibits excellent efficiency. In total, there are 2 timers and counters. Normal operation requires a supply voltage (Vsup) that is higher than 4.5V. Using an oscillator type of Internal, it works.
