The MB90F020CPMT-GS-9070 (hereinafter referred to as the MB90F02) is a microcontroller product developed by Fujitsu Semiconductor. Being a member of the MB90F02 microcontroller family, the MB90F02 integrates three different types of peripherals in a single device. This makes it a popular choice for embedded applications with limited space and limited operating power. In this article, I will discuss the application field and working principle of this microcontroller.

The MB90F02 is designed for high-speed applications in the automotive market such as engine control systems, body control systems, and infotainment systems. The processor features a dual-core architecture that allows for simultaneous execution of time-critical tasks and non time-critical tasks. The MB90F02 also features a highly advanced timer system and an Ethernet MAC module, making it suitable for various networked application scenarios. The processor also supports various analog peripherals, including a 10-bit A/D converter, an 8-channel PWM output, and a 6-channel digital-to-analog converter.

In terms of the working principle, the MB90F02 microcontroller uses a thread-based multi-tasking operating system, which allows multiple tasks to be executed simultaneously and efficiently. The on-chip memory includes four 32-bit registers and four 16-bit registers. The instruction set supports the M16C, MIX16C, and MIPS16 architectures, as well as a variety of instructions for data manipulation, memory manipulation, and external memory access. This makes the MB90F02 a suitable microcontroller for applications such as motor control, robotics, and even AV control.

The MB90F02 also features a variety of power-saving features to reduce energy consumption. The processor supports several types of power saving modes, including sleep, standby, and halt. These different power saving modes allow the processor to remain active but at a low power level. In addition, the MB90F02 also supports low-power logic functions, such as bus hold and bus release, to reduce overall power consumption.

The MB90F02 microcontroller also features a built-in DMA (Direct Memory Access) controller and external interrupt module. The DMA controller allows for data to be transferred between the on-chip memory and external devices with minimal processor involvement. The external interrupt module allows for fast and reliable external interrupt handling, eliminating the need for manual polling. This makes the MB90F02 ideal for applications such as motor control, robotics, and AV control.

In summary, the MB90F02 is a popular choice for embedded applications with limited space and limited operating power. Its dual-core architecture and various power-saving features make it ideal for applications in the automotive and infotainment markets. The MB90F02 also features an advanced timer system and external memory access, making it suitable for motor control and robotics. Finally, its built-in DMA and external interrupt modules allow for fast and reliable data transfer and external interrupt handling.
