The MB90F347CASPFR-GS-N2E1 is an 8-bit microcontroller with many applications in various industries. It has a wide range of features, such as a 128KB on-chip flash memory, 4KB on-chip RAM, 78 I/O port pins, five-stage pipeline architecture and multi-layer interrupt controller. These features make it suitable for different applications, such as automotive, consumer, industrial, medical and aerospace markets.

The MB90F347CASPFR-GS-N2E1 was designed to increase system performance and reduce power consumption. It is built with an advanced CMOS process, resulting in lower power consumption and also features a high-speed pLL bus that increases system speed by up to 32X. This microcontroller has advanced system management features, such as advanced thermal management, self-test and power-saving modes.

The MB90F347CASPFR-GS-N2E1 has a number of features that make it suitable for applications in embedded systems. It includes an on-chip boot-monitor that enables flexibility in the development of application firmware. This microcontroller also includes advanced peripherals such as an Altera NIOS II processor, a USB 2.0 controller, an integrated LCD controller, an Ethernet interface, an internal clock generator, and a dedicated debug port.

The MB90F347CASPFR-GS-N2E1’s working principle is based on traditional 8051 architecture. This microcontroller has 128KB on-chip flash memory and 4KB on-chip RAM. It is programmed in 8051 assembly language, which is compatible with other similar 8051 devices. The data is processed in the ALU, which of several ALUs, depending on the data type. The ALU is responsible for writing, editing and executing the commands.

The MB90F347CASPFR-GS-N2E1 has a five-stage pipeline architecture, which allows for much faster instruction execution. The five stages are: fetch, decode, execute, write back, and complete. Each stage is responsible for a different operation, and the instructions are executed in order. This does not mean that each instruction is necessarily executed five times; rather, each stage of the pipeline can be reused multiple times before completing the instruction. This helps increase system speed and efficiency.

The MB90F347CASPFR-GS-N2E1 also includes a multi-layer interrupt controller, which can process up to 16 requests simultaneously. This controller is responsible for saving and storing context information when an interrupt occurs, and then passing the request on to the processor or peripheral. The interrupt controller is also used to prioritize various requests and decide which requests have higher priority. This helps ensure that incoming requests are serviced in an orderly manner, minimizing interrupt latency and ensuring that no requests are lost.

In conclusion, the MB90F347CASPFR-GS-N2E1 is a powerful and efficient 8-bit microcontroller that is suitable for many applications in embedded systems. It has low power consumption and high system performance, thanks to its advanced CMOS process and five-stage pipeline architecture. The built-in features, such as the on-chip boot-monitor and interrupt controllers, enable flexibility in application development. The MB90F347CASPFR-GS-N2E1 can be programmed in 8051 assembly language and is compatible with other similar 8051 devices.
