Working Principle of MB90F347ESPMC3-GS-ER

The MB90F347ESPMC3-GS-ER is based on the 32-bit Renesas CPU core and supports the Renesas 32-bit instruction set architectures. It is based on a Harvard architecture, in which the program counter keeps track of the instructions to be executed while the data address bus manages data storage. This makes functioning of this microcontroller easier, flexible and faster.

At the heart of the microcontroller is the CPU core, which is responsible for executing the instructions that are written in the instruction memory. The instruction memory is divided into two parts: program memory and data memory. The program memory stores the instructions present in the application code, while the data memory stores the variables and data used in the program. The instruction and data memories can be directed from either the Internal RAM (IRAM) or from an external memory.

The connected peripherals are managed by the peripheral bus, which is connected directly to the CPU core via the bus interface unit. The bus interface unit is responsible for interfacing between the CPU and all the connected peripherals, and for controlling their access to the CPU. The peripherals can be managed separately as needed, as each peripheral has its own dedicated control registers.

The MB90F347ESPMC3-GS-ER is also based on a synchronous architecture, which ensures that the CPU core always runs at a predetermined and fixed rate. This simplifies the design of the microcontroller and ensures that the connected peripherals can always access the CPU core in a predictable manner.

Conclusion

The MB90F347ESPMC3-GS-ER is a powerful 32-bit embedded microcontroller that is used in a wide range of applications, from automotive and home appliances to industrial control systems. It is based on the 32-bit Renesas CPU core and supports the Renesas 32-bit instruction set architectures. Its excellent A/D converter performance and large on-chip memory make it an ideal choice for embedded applications. Its ability to directly access external RAM with zero wait states, and its built-in DMA controller and PMC also make it an attractive choice for embedded applications.
