Introduction

STM8S103F2U6TR is an 8-bit microcontroller designed and produced by STMicroelectronics. The device belongs to the STM8S “Low Density” family of devices with 1 Kbyte of Flash memory and 128 bytes of RAM. The device also includes two 8-bit timers and two 16-bit timers, one UAR, one I2C, one SPI and 7 channels of 10-bit A/D converters.The STM8S103F2U6TR is a low power, high performance device. It is a single integrated circuit and is pin and function compatible with its 8-bit predecessors ST7 and STM8 family of microcontrollers. The device is based on the STM8 processor core and features an 8-bit Reduced Instruction Set Computer (RISC) architecture.

Application Field

The device has wide application prospects in various fields. It is widely used in consumer electronics such as home appliances and audio systems, automotive electronics such as fuel injection systems, industrial controllers and automation systems, as well as medical equipment.For example, the STM8S103F2U6TR is used in automotive fuel injection systems for controlling engine speed, injection timing, fuel delivery, and air/fuel ratio. It is also used in home appliances and audio systems to control the operation of various functions. It is also used in medical devices such as pacemakers, electronic thermometers, pulse oximeters, and blood pressure monitors. In addition, the device is used in industrial automation and control systems, such as programmable logic controllers (PLCs) and industrial robots.

Working Principle

The STM8S103F2U6TR consists of a Central Processing Unit (CPU), Program Memory (PM), Data RAM (DRAM) and a Peripheral Subsystem (P-sub). The CPU is based on a Harvard Reduced Instruction Set Computer (RISC) architecture, which is optimized to minimize the instruction execution time and maximize the performance of the device.The PM consists of Flash memory which is used to store the application program code. The DRAM is used to store the application data. The P-sub holds the various peripheral devices that help the CPU execute various tasks. This includes the Timers, UARTs, I2C, SPI, ADC, and other I/O modules.The CPU works in tandem with the peripheral devices to carry out the instructions stored in the PM. The CPU communicates with the peripheral devices through software instructions, which are then executed by the respective peripheral devices. For example, the CPU can send the instruction to the Timer to start the timer, and wait for the timer to expire. After the timer expires, the CPU can then execute the next instruction.The STM8S103F2U6TR is programmed using the STC microcontroller development suite (STVD). STVD provides a graphical user interface (GUI) that allows developers to write applications using the Modula-2 development language. Other development tools like C compilers are supported by the device.

Conclusion

In conclusion, the STM8S103F2U6TR is a low power, high performance 8-bit microcontroller which is widely used in various applications such as automotive fuel injection systems, home appliances and audio systems, industrial controllers, medical devices, and other automation and control systems. The device is easy to program and debug using the STC microcontroller development suite (STVD). The device is pin and function compatible with its 8-bit predecessors, making it an excellent choice for embedded applications.
