Embedded systems refer to a system that incorporates computer hardware and software, and the application field is wider and more versatile. Microcontrollers are the main force in embedded technology. In general, microcontrollers refer to tiny, single-chip computers with built-in central processing unit (CPU), random access memory (RAM), non-volatile memory (Flash or EPROM) and I/0 (input/output) ports. The LC87F17C8AUWA-2H microcontroller is one of the most commonly used microcontrollers. This article will discuss the application field and working principle of the LC87F17C8AUWA-2H microcontroller.

The LC87F17C8AUWA-2H microcontroller is a low-cost, 8-bit low power microcontroller, with ROM up to 8K x 16, RAM up to 256 x 8, and I/O up to 33 x 5. It is widely used in the design of embedded systems. It is suitable for applications such as instruments, display equipment, audio and video products, automotive electronics, game machine peripherals and other small control systems.

The working principle of the LC87F17C8AUWA-2H microcontroller is simple and clear. First, the instructions set by the software in the microcontroller are converted into executable instructions by the on-chip program memory. When an interrupt request is received, the on-chip data memory stores the address of the instruction to be executed, so that when the interrupt is enabled, the instruction can be executed smoothly. Secondly, data operation is realized through the core of the load-store architecture, which provides the boundary between the CPU and the data memory and other device access.

The LC87F17C8AUWA-2H microcontroller features an 8-bit central processing unit (CPU) with an effective operating frequency of 3.2MHz, an 8K x 16 program memory with an access time of 0.8 microseconds, 256 x 8 random access memory (RAM), 32 pins of digital I/O, and eight 8-bit and one 16-bit timer/counter. It is integrated with a voltage regulator for 4-6v input range and a watchdog timer for application safety. The microcontroller also has a useful complementary on-chip peripheral, including serial port (SPI), 8/4 channel/capture/compare PWM, and 8/4-channel A/D conversion.

In addition, the LC87F17C8AUWA-2H microcontroller provides a wide selection of operating modes and flexible power control options, making it suitable for applications requiring precise timing and low power consumption. Its low power characteristics enable the system to support both low current sleep and power-down mode operations. The microcontroller also features an I/O port selectable interrupt type and includes two on-chip programmable pull-ups.

The LC87F17C8AUWA-2H microcontroller is a versatile, low cost and low power embedded device. Its application field is very wide, and the working principle is simple and clear, which makes it very popular in the design and development of embedded systems.
