The MB90F023PF-GS-9022 is a 32-bit microcontroller from the MB90Fxxx series from Fujitsu. This MCU is designed for embedded applications and has useful features like built in flash memory, serial peripheral interface (SPI) and interrupt vector table. The ultra low power consumption makes it suitable for battery powered applications, where space is limited and weight is a concern. This MCU is based on the Fujitsu FR RISC processor and features abundant on-chip peripheral functions.

The application of MB90F023PF-GS-9022 is in automotive and home appliances. It can be used in tasks such as motor control, communication control, display control, and diagnostic system control. This microcontroller is also used in fuel injection systems, braking systems and ABS controls due to its robust 32-bit core.

The MB90F023PF-GS-9022 has two pin modes that are Low Pin Count (LPC) configurable and High Pin Count (HPC) configurable. The LPC mode uses 32-bit registers and provides connections for serial communication, AD conversion, I/O control and real-time clock input/output. In the HPC mode, it provides up to 52 I/O connections. It also includes a gear reduction capability to reduce the number of pins necessary for configuring the device.

The MB90F023PF-GS-9022 integrates a functional Clock Monitor function. This function detects abnormality in the system clock and performs appropriate processes. In addition, it supports an External Interrupt Service Routine (ISR) which supports an interrupt vector table. This vector table is used to process interrupts in an efficient and predictable manner, thus reducing the code size required for interrupt handling.

The MB90F023PF-GS-9022 also offers hardware boundary scan support, allowing users to observe internal nodes during production and maintenance activities. The scan test extends node visibility outside of those accessible through the normal I/O pins. This is especially useful when working with complex systems where internal node states are difficult to observe with traditional methods.

The MB90F023PF-GS-9022 is a very energy-efficient microcontroller and operates at lower power consumption than many similar devices. With its low power consumption, it can be used for important tasks such as controlling digital systems, communication protocols, and automotive applications.

The working principle of the MB90F023PF-GS-9022 is relatively straightforward. The MCU is based on the FR family of processors and is designed to be compatible with a wide range of microprocessors. This versatility gives it the capability to work with a variety of platforms, and to be used in a wide range of applications.

The MB90F023PF-GS-9022 includes several on-chip peripheral functions, such as: a serial peripheral interface (SPI); interrupt vector table; two pin modes, Low Pin Count (LPC) and High Pin Count (HPC); a functional Clock Monitor; and, a hardware boundary scan.

The serial peripheral interface (SPI) allows for communication with external devices and peripherals. This is useful for applications that require multiple external devices and peripherals, such as communication control, motor control, and display control.

The interrupt vector table is used to map all of the interrupts within the MCU, and to allocate appropriate processor resources for handling each interrupt. This reduces the time and complexity of programming for interrupt-driven devices. The Clock Monitor function is used to detect system clock abnormality and to take appropriate action if an abnormality is detected.

The hardware boundary scan feature allows for a more detailed inspection of the internal nodes of the MCU. This is especially useful when it comes to the maintenance and repair of a complex system.

The MB90F023PF-GS-9022 is a powerful and versatile microcontroller. It is suitable for use in automotive applications, communication protocols, and digital systems due to its low power consumption and compatibility with a wide range of microprocessors.
