AT87C51RD2-RDTUM belongs to the Embedded - Microcontrollers class. It is a 8-bit CMOS Flash Microcontroller. It has an 8 kB Flash memory and 256 bytes of on-chip SRAM. This microcontroller unit has two serial communication ports: UART and I2C, a 256-byte ROM, and an 8-bit timer/counter unit. Additionally, the AT87C51RD2-RDTUM also provides three 16-bit timer/counters and four 8-bit, pulse-width-modulated (PWM) output pins.

The AT87C51RD2-RDTUM is designed for applications that require precise timing and low power consumption. It can be used for applications such as automotive control systems, industrial controllers, medical devices, security systems, and consumer electronics. Its low power consumption makes it ideal for battery-powered applications as well.

The AT87C51RD2-RDTUM can execute up to 13 MIPS (million Instructions per second) of instruction. It features a number of peripherals such as 3 channels of a 10-bit ADC, a watchdog timer, an analog comparator, four PWM outputs, and two serial ports. The hardware incorporates a Harvard architecture serial programming/debugging interface that enables in-system programming/debugging of the AT87C51RD2-RDTUM using a PC-Based software development system. Furthermore, the AT87C51RD2-RDTUM has a self-reprogrammable flash memory that allows the user to program and debug the unit in-system.

The working principle of this microcontroller unit is based on the Von Neumann architecture, which divides the memory into two parts. One part is for storing the instructions and data, while the other part is for code memory or program memory. The instructions in the program memory are executed sequentially, one after the other, as directed by the Control Unit. The instructions are fetched from the program memory and executed by the processor. The processor then fetches the data from the data memory and executes commands accordingly.

The AT87C51RD2-RDTUM contains a 300-MHz internal oscillator, which can be divided down to five different clock frequencies. It also provides multiple clock sources, including an external clock input and an external clock output. The processor features five general-purpose 8-bit I/O ports and two 16-bit I/O ports for interfacing with external peripherals such as LEDs and displays. In addition, the AT87C51RD2-RDTUM has interrupt handling capabilities, allowing the processor to respond to external interrupts quickly.

In conclusion, we can say that the AT87C51RD2-RDTUM is an ideal microcontroller for embedded applications. It is a high-performance 8-bit device that provides an attractive combination of low-power consumption and powerful instruction set, making it a great choice for a wide variety of embedded applications. It is an optimized device for low-power applications such as automotive and medical, as well as for high-performance applications such as industrial control systems.
