STR755FR2H6 is an advanced 8-bit microcontroller with power and performance capabilities. It is widely used in multiple application fields for its flexibility, stability, and reliability. This article explains the working principle and applications of STR755FR2H6.

Introduction

STR755FR2H6, produced by STMicroelectronics, is an advanced 8-bit microcontroller based on the ARM7TDMI-S processor and featuring 32kB on-chip Flash, 4kB RAM, a 16-bit timer, UART, PWM timer, real-time clock, and up to 45 I/O ports. As one of the most popular microcontrollers in the embedded world, STR755FR2H6 has been used to produce various embedded systems in various application fields including industrial, consumer, and automotive.

Working Principle

The STR755FR2H6 microcontroller operates through a 32-bit data bus and an instruction register that contains the program sequence for each application. When powered on, the microcontroller fetches the program code from the on-chip Flash program memory in order to execute the requested operation.The microcontroller operates in two modes, either in the Supervisor mode or the User mode. In the Supervisor mode, the processor can access the entire flash memory to retrieve the program code and execute it. In the User mode, the processor can only access a predetermined memory range.When an instruction is fetched from the Flash memory, the processor decodes it and initiates the appropriate operation such as arithmetic and logic operations, audio playback, serial communication, or other specific operations.
