AT89LP51RD2-20AU Overview


It is available in the 44-TQFP package for the benefit of saving space. In this case, it is mounted using the method of Surface Mount. It comes in a Tray package. Devices with 8051 core processors are available. Working at -40°C~85°C TA temperature is recommended. FLASH is its program memory type. 40 I/Os are present on the device. A component with the same part number as AT89LP51RD2 can be compared to other similar components. At QUAD, its terminals are located. 44 terminationals are present. The 89LP series includes this electrical component. Because of the 3V voltage of the supply, high efficiency can be achieved. UPs/UCS/Peripheral ICs of this gadget are MICROCONTROLLER in order to monitor their performance. The structure is composed of 44 pins. The mounting of this device is carried out following the method of Surface Mount. Subcategory Microcontrollers includes this component. Using the devices' 64kB memory size, you can store programs and data. A maximum supply current of 7mA is set. Power is provided by a 2.5/5V source. This device works well at 20MHz frequency when it is operating at a high rate of efficiency. 3 counters/timers are currently active. A chip with 36 programmable inputs/outputs is available. Normally, the supply voltage (Vsup) should remain above 2.4V. Using an oscillator type of Internal, it works.
