AT89LP51RD2-20MU Product Details

AT89LP51RD2-20MU Overview


The package is in 44-VFQFN Exposed Pad format. The MCU has 40 I/O ports. There is a mounting type Surface Mount associated with this Microcontroller. This Microcontroller is based on the 8-Bit core. There is a memory type of FLASH in its program memory. The temperature range that this Microcontroller operates at is -40°C~85°C TA. The electrical component that you are looking at belongs to the 89LP series of components. Microcontroller has abundant program memory size of 64KB 64K x 8. The 8051 Core Processor powers the device and is one of its key features. This Microcontroller belongs to the MICROCONTROLLER uPs/uCs/peripheral ICs type. During the manufacture of the IC chip, there is a number 44 of terminations. A 8-bit operation is performed by this part. There is an output of 3V volts from the Microcontroller chip. A total of NO DMA channels are available on MCU chip. This MCU is implemented with 64kB memory. AT89LP51RD2 serves as a base part number to find alternatives. It exhibits good efficiency when it operates at a frequency of 20MHz and it is able to operate at a high frequency. It is possible for the device to work with the motor using the PWM channel YES. It is possible to access the 44 pins on the chip through the 44 pins. It is equipped with 3 timers and counters. As far as the CPU is concerned, it is embedded with the the 8051 family of processors. There's an integrated FLASH memory in the equipment. There is a 8051 core architecture integrated into it. Among the eight programmable I/O sections, there are many different ways in which it can be programmed.
