MB89985L-G-217-CHIP application field and working principle

MB89985L-G-217-CHIP is a 8-bit single-chip microcomputer chip, designed and manufactured by Mega Blox Company. It is designed for entry-level embedded applications in the industrial and consumer fields, covering uanalog, digital and communications fields, control areas such as robots and automation devices, real-time applications, and more.

The MB89985L-G-217-CHIP features a central processing unit (CPU), a random access memory (RAM), a program memory (ROM) and a set of built-in peripherals. It also has an 8 bit Accumulator and 3 8 bit registers.

The CPU of this chip is based on the RISC architecture, providing four execution units for coding, debug, timing control, and memory access control. A global bus system ensures that all the necessary signals are managed. The RAM of this chip is a low-power, double-data RAM, designed for faster data synchronization. The ROM is the latest memory unit with a wide range of data protection features.

The digital I/O pins included on this chip are used for digital control applications. The analog input/output pins can be used for analog I/O applications. The serial communication ports provide the interface for digital control, for example, setting the baud rate, data transmission and reception, and so on.

The other key features of this chip include an integrated pulse width modulation controller, timers, serial peripheral interface, an eight-bit operation transcoding unit, an 8-bit arithmetic and logic unit, and a high-speed memory management controller.

The MB89985L-G-217-CHIP is suitable for low-cost, high-performance applications in the field of industrial and consumer product control, robotics and automation, medical and automotive control, embedded systems, and so on. Its user-friendly, quick development capabilities make it an excellent choice for embedded system applications.

The working principle of the MB89985L-G-217-CHIP is relatively simple. The chip is built with four main components: the CPU, RAM, ROM, and the set of built-in peripherals. All these components are connected to each other and operate in tandem to facilitate efficient system performances.

The main interface between the CPU, the RAM, and the ROM are the bus system. The bus system consists of various components such as the address bus, data bus, and control bus, which are used for the transfer of commands, instructions, and data between the CPU and the peripherals.

The MB89985L-G-217-CHIP has two instructions, LOAD and STORE, used for the transfer of information between registers and memory. The CPU uses these instructions to initiate data movement between memory and registers. The CPU initiates data movement between a memory cell and an accumulation register through the LOAD instruction, and stores the contents of the memory cell in the accumulation register via the STORE instruction.

The microcontroller also has two 8-bit eight-bit arithmetic and logic units for addition, subtraction, multiplication, and division. This unit can be used to perform arithmetic operations, and logic operations such as bytewise AND operations. The PWM controller is used to control digital output pins and set their high/low logic levels. The serial communication ports, analog I/O pins, and digital I/O pins are also used for communication between the chip and the external devices.

The MB89985L-G-217-CHIP offers an unprecedented level of integration for embedded system applications, making it a cost-effective solution for entry-level embedded projects. Embedded systems designers can take full advantage of the MB89985L-G-217-CHIP’s robust set of features to develop efficient systems.
