AT89C51RE2-RLTUM Product Details

AT89C51RE2-RLTUM Overview


A 44-LQFP package is included. In total, it has 34 inputs and outputs. This Microcontroller is mounted using the Surface Mount mounting type. Powered by the 8-Bit core, it offers a wide range of capabilities. The type of memory that the program uses is FLASH. The temperature range of this Microcontroller is within the range of -40°C~85°C TA. 89C series components belong to this electrical component. Its program memory size is 128KB 128K x 8. There is a 80C51 Core Processor inside MCU that provides this device with its power. MICROCONTROLLER uPs, uCs, and peripheral ICs make up the Microcontroller. The part works on a 8-bit basis. The Microcontroller chip has NO DMA channels. 128kB memory size belongs to the part. AT89C51RE2 is the base part number that you can use to find alternatives. A good performance can be achieved at a frequency of 60MHz, as long as it is operated at a low power consumption. In order for the device to work with the motor, it utilizes the PWM channel YES. On the chip, there are 44 pins that are accessible. A total of 3 timers/counters are included in the package. A total of 44 pins are present. Devices based on the 8051 series of CPUs are embedded in the device. There's built-in FLASH memory in the equipment. It is built on a 8051 core architecture. This 8 Programmable I/O section allows you to program the device in many different ways depending on what you need. As a few examples, there are additional features like ALSO OPERATES AT 2.7V SUPPLY that are available in the software.
