The MB9AF312KQN-G-AVE2 is an advanced MCU specifically designed for the automotive sector that looks to increase safety with reliable performance. The microcontroller is part of the MB9AF3xx family from Fujitsu Microelectronics, featuring a 32-bit Arm Cortex-M3 core running at a frequency of up to 80 MHz. With this product, its main application fields range from automotive body control systems to embedded control systems.

The MB9AF312KQN-G-AVE2 is equipped with 128 KB of ROM memory, 16 KB of RAM memory, and Flash memory, allowing developers to store data and code directly on the device. Other integrated modules are an oscillator circuit and the latest Analog Digital Converter (ADC) that allows measuring analog signals from various sources and converting them into digital signals that can be read by the microcontroller. Included in the package are a Real-Time Clock (RTC) for time-keeping and an accurate watchdog for detecting malfunctioning.

The MB9AF312KQN-G-AVE2 also features strong security and integrity thanks to the presence of two integrated virtual memory management units (MMU) which protect user-defined areas of memory from malicious or accidental corruption. Furthermore, the microcontroller has advanced cryptographic algorithms to protect data and access control mechanisms.

In terms of safety, the MB9AF312KQN-G-AVE2 performs very well due to a range of hardware and software fault protection functions, including ECC error detection in code and data memories, checksums, and parity. The microcontroller also supports multiple external interfaces, such as CAN, LIN, GPI, and Keypad, which allow direct connections to automotive electronics.

Developers can make use of the integrated packet-based debug system (On-Chip Debug), which enables real-time debugging at source level. This helps developers check the status of programs, detect errors faster, and refine the code for production-grade efficiency. The integrated clock must be configured before the microcontroller can be used, which is done using the Oscillator Calibration Circuit (OCC). Additionally, the MB9AF312KQN-G-AVE2 is equipped with a 12-bit ADC, which provides accurate measurements and has a temperature range between -40°C to +125°C.

In summary, the MB9AF312KQN-G-AVE2 offers a range of features that make it an excellent choice for automotive body control systems and embedded control systems that require reliable performance and strong security measures. Its range of external interfaces, powerful debug system, and the presence of MMU, ADC, and RTC further give it an edge that can be used to increase safety and efficiency.
