The TS80C51RD2-LIA embedded microcontroller is an 8051 family core chip developed by Phoenix Technologies Company. It integrates two 2.4576MHz-8MHz crystal oscillators, 2Kx16 ROM, 128/256 Bytes RAM, an 8-bit CPU, and various peripheral functions in one IC package. It is widely used in household appliances, audio, communications, medical and other fields. Its working principle is as follows: when the power is turned on, the system starts to run with the help of the crystal oscillator, and starts to execute the program from the ROM. The program sent by the user instructs the system to execute the corresponding operations, for example, read the signals from the environment and control the operations of the connected peripherals accordingly. When the operation is done, the system will still execute the same program from ROM until the power is off.

The TS80C51RD2-LIA embedded microcontroller provides a wide range of peripheral functions. It integrates two 32-bit long Array Pointers, and two 8-bit bit-addressable accumulators. It also provides a 16-bit A/D convertor, two parallel ports, two serial communication interfaces (UART), a 4-channel 16-bit Full Duplex Timer, two additional Timers or Event Counters, 40 programmable I/O Ports, and a watchdog timer, which can ensure the reliable operation of the system. Moreover, it integrates two crystal oscillators, whose frequencies can be set between 2.4576MHz and 8MHz. With these functions, the TS80C51RD2-LIA increases system reliability and reduces design complexity.

The TS80C51RD2-LIA embedded microcontroller is widely used in household appliances and other fields. In the domestic appliances, it is usually used for controlling the operations of washing machine, air-conditioner and other appliances. Besides, since it supports multiple serial communication protocols, such as RS232, SPI and IrDA, it is also widely used in audio and communications devices. Besides, with its low-power sleep and idle modes, it is also a popular choice for medical applications, such as patient monitoring, medical imaging, and medical instruments.

In conclusion, the TS80C51RD2-LIA embedded microcontroller is a versatile, low-cost and low-power MCU chip. With dual crystal oscillators, multiple peripheral functions, and a wide range of applications, it is an ideal choice for embedded applications.
