Embedded systems have a wide range of applications, and microcontrollers are an important component of embedded systems. One of the most widely used microcontrollers is TSC87251G2D-24CE. Here we\'ll take a look at its application field and working principle.

Application Field

TSC87251G2D-24CE is widely used in many applications, including industrial automation, medical instrumentation, automotive electronics, consumer electronics and telecommunications. It is especially suitable for wireless communication systems using 2.4GHz frequency range. It supports CAN protocol, making it easy to integrate into CAN networks. It can also process various kinds of data from sensors and other devices.

Working Principle

The TSC87251G2D-24CE is an 8-bit microcontroller based on the MCS-51 family of CPUs. It contains an 8-bit ALU and eight 8-bit addressable general-purpose registers. It also has a built-in clock generator, program memory, data memory and input-output ports. The chip also contains an interrupt unit which allows the microcontroller to respond to external events.

The CPU of TSC87251G2D-24CE uses Harvard architecture, which means separate code and data memory. This allows the program code to access both the code and data memory and allows simultaneous execution of instructions. The 8-bit ALU can perform all basic arithmetic and logic operations.

The TSC87251G2D-24CE is equipped with a built-in clock generator that can produce basic 1MHz clock frequency. It can also be set to produce higher frequencies, up to 12MHz. The clock generator also supports crystal oscillator and RC oscillator for higher accuracy and stability.

To interface with external devices, the controller has three bidirectional 8-bit data ports—P0, P1 and P2. It also has two 6-bit addressable ports—P3 and P4. The ports can be programmed to serve various kinds of input-output operation.

TSC87251G2D-24CE is also equipped with built-in analog-to-digital converter and digital-to-analog converter. These allow the controller to process analog signals in the digital domain. The onboard CAN controller supports CAN protocol, making it suitable for automotive application.

The controller also contains internal watchdog timer and several other timers. It also has power-saving features, such as power-down and idle mode, which help reduce power consumption.

As one of the most popular microcontrollers, the TSC87251G2D-24CE has wide range of application and is very flexible in terms of its features. With its combination of Harvard architecture, peripheral features and power-saving features, it is suitable for many types of embedded systems.
