The AT87C51RD2-RLTUM embedded microcontroller is a popular choice among device manufacturers because it has small size and large feature set. Originally developed by Atmel, this 8-bit microcontroller is designed to provide the necessary computing power to perform complex tasks with minimal power consumption. The microcontroller can be used in a variety of applications, such as automotive, consumer electronics, industrial, medical, and networking.

The AT87C51RD2-RLTUM is based on Atmel\'s proven AT87C51RD2-L 81C51 core with enhanced features such as low power consumption, enhanced interrupt controller, and improved serial communications. The microcontroller features a 64Kbyte ROM and 256 bytes of RAM. It supports a wide range of on-chip peripherals and built-in system functions, including ADC, timer, built-in LCD controller, 3-level interrupt controller, 2 timer/counter, pulse width modulation (PWM), UART, SPI, I2C, EEPROM, and temperature sensor.

The AT87C51RD2-RLTUM core is a stepwise improved version of the traditional 8051 core. It supports various instruction sets, such as direct addressing, program memory addressing, and relative addressing. Its memory mapping allows the use of conventional memory areas such as ROM and RAM, as well as dedicated sub-registers and special function registers (SFRs). Its interrupt structure provides two levels of interruptions, while its UART adds flexible support for up to 32 additional data bytes.

The AT87C51RD2-RLTUM microcontroller is widely used in a variety of applications due to its low power consumption and its versatility in low- and high-level programming. The microcontroller is suitable for use in automotive, consumer and industrial applications. It has a wide range of integrated solutions, including motion control, audio, communications, and Internet of Things (IoT) applications. It can also be used for data acquisition systems that process environmental variables, such as temperature, pressure, and humidity. Due to its low power consumption and cost-effectiveness, the microcontroller is also widely used in medical, automation, and industrial applications.

The working principle of the AT87C51RD2-RLTUM microcontroller is based on a Harvard Architecture. It has separate memory areas for instruction and data. The data is held in RAM, while the program instructions and constants are stored in the ROM. Before the processor can execute any instruction, it must first receive and decode the instruction. Then, it will execute the instruction and store the result in the designated memory locations.

The AT87C51RD2-RLTUM microcontroller is programmed through the Atmel Studio 7 software. The device features powerful in-system programming (ISP) capability that enables both device-level updating and onboard programming of the AVR family of flash microcontrollers. The device can also be programmed using third-party applications such as JTAG, I²C, and SPI.

The AT87C51RD2-RLTUM microcontroller is a popular choice for device manufacturers and designers due to its small size and its ability to perform complex tasks with minimal power consumption. It features a variety of integrated peripherals, built-in functions, and on-chip debugging. It is suitable for use in automotive, consumer, industrial, medical, and networking applications due to its low power consumption and cost-effectiveness.
