TWR-MPC8309 Application Field and Working Principle

The TWR-MPC8309 evaluation board is an example of an embedded system. It refers to computer systems that are embedded into a product that serves a specific function. The TWR-MPC8309 is an evaluation board based on the Freescale MPC8309 processors and contains modules for graphical, communication, and storage evaluation.The primary application of the TWR-MPC8309 is to evaluate the performance and function of the processor and modules that are integrated into the evaluation board. This evaluation board can be used for a variety of applications including data acquisition, medical technology, building automation, industrial control, and others. The board also carries an integrated USB host and device interface to enable it to interact with peripherals. The board includes two microprocessors, a SDP-S diAGP-S and a TQMa7 135 processor. The SDP-S is a system-on-chip (SoC) while the TQMa7 135 is a quad-core Cortex-A7 processor with integrated graphics and memory controllers. The board also has two DDR3 memory controllers, several UARTs, one CAN bus controller, two PCIe controllers, and up to four USB controllers. The SoC provides the entire embedded system some of its capabilities. The SOC integrates several components onto one device such as the CPU, memory, and peripherals with a logic system. The front-end of the processor supports a wide variety of hardware configurations which provides developers flexibility. The embedded system also carries the integrated Freescale PCM-MPC8309 processor.The purpose of the processor is to help manage the bandwidth characteristics of peripherals and ensure real-time response of the system, making it suitable for use in embedded applications. This processor offers several advantages over earlier processors such as its more efficient data communication and larger address space. It can also run multitasking applications with complex algorithms.The two memory controllers on board are designed to manage access to large amounts of data quickly and efficiently. The DDR3 memory controllers support up to 2 Gbytes of DDR3 memory. This allows the board to support streamlined data movement for fast, rapid and reliable data storage and mixed-mode data transfers.The board also has a variety of communication ports. It contains up to two universal asynchronous receiver transmitters (UARTs) and up to two controller area networks (CAN). It also includes one PCIe controller which supports Gigabit Ethernet as well as peripheral component interconnect (PCI)/Enhanced peripheral component interconnect (ePCIe) devices. In addition, the board carries up to four USB controllers for communicating with external peripherals. The processor also carries Freescale’s System Management Unit (SMU) to control the system. This system management unit (SMU) provides functions such as reset, power-on reset, and programmable watchdog timer for resetting the system in case of an unexpected fault condition. The SMU also provides strategies for data encryption, secure boot, and thermal control in case of excessive heat.The TWR-MPC8309 evaluation board carries great potential for embedded applications due to its various features and capabilities. This is a great board for developers to explore and use for various projects. It is suitable for data-acquisition, medical technology, building automation or industrial control applications. With its advanced microprocessors, peripherals, and memory controllers, the TWR-MPC8309 board is an ideal tool for embedded system development.
