SPC5747CK1CMJ2 Application Field and Working Principle

Introduction

The SPC5747CK1CMJ2 is a 32-bit Automotive Microcontroller (MCU) developed by Freescale Semiconductor. Being part of the SPC57xx family it offers significant metrics in automotive control. The SPC5747CK1CMJ2 is a mid-range MCU in the SPC57xx series and provides an excellent mix of features, performance, and cost. It is targeted at low-end to medium-end real-time embedded system applications in areas providing an ideal balance between performance, cost, power consumption and total system cost, such as automotive control, radio remote control, and industrial automation.

Application Field

The SPC5747CK1CMJ2 is an ideal choice for medium cost embedded applications. It combines maximum performance with the lowest power consumption and is ideally suited for automotive control applications. With its low-end MCU architecture, it is ideal for applications such as powertrain, body and safety, comfort, and networking. It can be used in a variety of applications, including real-time motor control; engine control and support; vehicle control systems (VCS); powertrain control and support; chassis control and support; security and body control and support; GPS navigation systems; and communication systems.

Working Principle

The architecture of the SPC5747CK1CMJ2 allows for a real-time response to events and mostly automated system operation. To accomplish this, the MCU utilizes a multi-level interrupt system, which includes a core level interrupt, a peripheral level interrupt, and a system level interrupt. The core level interrupt is triggered by an event external to the MCU, such as the reception of a CAN message or external input. The peripheral level interrupt is triggered by an internal peripheral, such as a timer or digital-to-analog converter (DAC). The system level interrupt is used to monitor core-level and peripheral-level interrupts, manage interrupts, and perform system-level time management functions.The SPC5747CK1CMJ2 also utilizes a 4-level interrupt architecture, which allows for 4 levels of context-sensitive interrupts. This allows for a range of additional system control functions without sacrificing performance. Context switching for efficient interrupt management is provided, as well as autonomous control of individual peripherals separate from the application core logic. The powerful programming engine of the SPC5747CK1CMJ2 further allows for fast and efficient parameter changes, allowing for rapid system operation without compromising system stability.

Conclusion

The SPC5747CK1CMJ2 is an excellent choice for embedded applications in the automotive control field. The processor architecture is quite advanced, offering a multi-level interrupt system and a 4-level interrupt architecture to provide maximum control and performance with minimal power consumption. This processor provides an ideal balance between performance, cost, and power consumption, making it an excellent option for embedded applications requiring a mix of performance, cost, and power.
