AT89LP51RD2-20JU Overview


Due to its space-saving qualities, it is available in the 44-LCC (J-Lead) package. It is mounted using the way of Surface Mount. You can find it in the package of Tube. A 8051 core processor powers the device. 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. It has a number of 40I/Os. To find equivalent components, use its AT89LP51RD2 base part number. QUAD is the location of its terminals. It has 44 terminationals. The electrical component is part of the series 89LP. Because of the 3V voltage of the supply, high efficiency can be achieved. It has uPs/uCs/Peripheral IC - MICROCONTROLLER. There are 44 pins used in the construction of this device. A method of mounting is used, which is Surface Mount. The component is included in Microcontrollers. Memory size for the devices is 64kB, which can be used to store programs and data. The maximum supply current is set at 7mA. Powered by a 2.5/5V source. At a frequency of 20MHz, it can achieve excellent efficiency. There are currently 3 timers/counters set up on the system. 36 is the number of programmable I/O. A supply voltage (Vsup) above 2.4V is necessary for normal operation. Using a Internal oscillator type, it works well.
