MN101CF49KXN is a single chip microcontroller, part of the MN101C family manufactured and sold by Fujitsu Microelectronics. Specifically this microcontroller is a variant of the MPU type microcontroller utilizing a RISC CPU. It is capable of 16-bit computing providing bit-wise and physical addressing, along with 5 interrupt inputs, 4 16-bit timers, 10-bit A/D converter, bootrom and maskROM.

Application Field & Working Principle

MN101CF49KXN microcontrollers are generally used as embedded controllers in consumer electronics. This could include applications such as audio visual equipment and consumer white goods such as refrigerators and washing machines. Also thanks to their small size, low power consumption and cost, they are also suitable for remote applications such as in alarms and security systems.

The advantage provided by this microcontroller is the flexibility and adaptability it offers to the user. The microcontroller has a set of peripherals and peripherals can be connected to the microcontroller through its multiple connections. This means that the core of the system and the functions of the system can be tailored according to the user’s requirements. Examples of the functions of the microcontroller could include data acquisition, system monitoring and control, signal conditioning, motion control and many more.

The microcontroller also provides the user with digital and analog signals that are easily accessible and are quite reliable. This enables users to be able to use the controller for real time applications such as robotics, data processing and digital signal processing.

The working principle of this microcontroller is similar to other microcontrollers. It contains a core CPU and a set of peripheral circuits all incorporated into one integrated circuit. The MN101CF49KXN microcontroller has a 32-bit RISC CPU which is capable of 16-bit computing and provides bit-wise and physical addressing. It also has 4 16-bit timers, 10-bit A/D converter, bootrom and maskROM, 5 interrupt inputs and an on chip ROM which is 32kbytes in size.

The CPU is connected to the following peripherals such as SI/O, timers, A/D converter, SRAM and ROM. The RAM module is used to store temporary data whereas the ROM is a non-volatile storage which can be used to store both code and data. The SRAM which is available on the microcontroller acts as a scratchpad memory and does not require power for storage of data.

The general purpose I/O ports allow users to control microcontroller externally such as through connecting to switches, sensors and other microcontroller peripherals. The timer modules of the microcontroller are very useful in industrial control applications and are used to time the functioning of certain circuits or devices. The A/D converter is used to convert analog data into digital which can be used by the microcontroller’s processor.

The maskROM is an integrated feature which is used to store code executables which are firmware programs. The code contained in the maskROM is fixed in size and is not programmable. This type of ROM is not used for storing large programs so it is limited in its uses. The bootROM on the other hand is used for programs which do not require frequent updates and is mainly used for startup and system diagnostic purposes.

Overall, the MN101CF49KXN microcontroller is a powerful and versatile device that can be used in many applications and embedded systems. Its low cost, small size, and low power consumption make it a suitable fit for many consumer electronics as well as remote applications such as security systems and alarms. Additionally, its ability to connect to peripherals and its wide range of functions make it a strong choice for industrial control applications.
