AT89LP51RB2-20MU Overview


A space-saving advantage is that it is included in the 44-VFQFN Exposed Pad package. A Surface Mount mounting method is used. In the package Tray, it is included. With a processor of 8051 cores, the device is powered. During work, the temperature should remain at -40°C~85°C TA. There is FLASH program memory in it. 40 I/Os have been provided by the device. It has a base part number of AT89LP51RB2 that can be used to find other components that are comparable. The terminals are positioned at QUAD. As far as terminations are concerned, there are 44 terminations present. It is a member of the 89LP series of electrical components. The supply voltage of 5V allows for high efficiency. In data storage, FLASH, ROM is used as the memory type. In this gadget, MICROCONTROLLER is the device's uPs/uCs/Peripheral IC. For its construction, 44 pins are used. Based on the Surface Mount method, it is mounted. Subcategory Microcontrollers includes this component. A device with a memory size of 24kB can store programs and data. A 2.5/5V source is used for powering it. It is highly efficient when it works at a frequency of 20MHz. A total of 3 timers/counters have been set up. During normal operation, the supply voltage (Vsup) should be kept above 2.4V. The oscillator type Internal is used to operate the device.
