AT91M42800A-33AU Overview


To save space, it is included in the 144-LQFP package. In this case, it is mounted using the method of Surface Mount. Tray is the package that contains it. A core processor of ARM7? is present in the device. The temperature should be kept at -40°C~85°C TA while working. There is ROMless program memory in it. It has a number of 54I/Os. Based on its base part number of AT91M42800A, other similarly-sized components can be found. The terminals are positioned at QUAD. 144 terminations are present in it. AT91 is the series number of this electrical component. Because the supply voltage is 3V, high efficiency can be achieved. Memory type FLASH, ROMless is used for data storage. uPs/uCs/Peripheral IC for this gadget is MICROCONTROLLER, RISC. The structure is composed of 144 pins. Mounting is performed in accordance with Surface Mount. This component is a part of Microcontrollers. ARM is the foundation of its architecture. A 3/3.33/5V power source powers it. At a frequency of 33MHz, it can achieve excellent efficiency. 3.3V offers full adaptability and voltage supply when it is employed by designers. In total, there are 6 timers and counters. ALSO REQUIRES 5V SUPPLY also belongs to it. It works with an oscillator type External.
