TQM8548 – a compact module for high-speed communication

With the TQM8548 TQ-Components has added another high-performance module using a CPU from the Power QUICC III family to its product lineup
TQM8548 – a compact module for high-speed communication (PresseBox) (Weßling, ) Based on the MPC8548 processor from Freescale, the TQM8548 is predestined for applications that demand high computing power along with a high data rate for the communication interfaces. At more than 3,000 MIPS and running at 1.3 GHz, the MPC8548 is one of the highest-performance processors currently available using the Power architecture. Including an internal memory of up to 2 GB DDR2-SDRAM, a NOR-Flash memory of up to 256 MB for program code, and NAND-Flash memory of up to 8 GB for additional data, the module contains more than enough reserves for virtually all conceivable applications.

In addition to high computing power, the TQM8548 is also impressive in terms of the large number of available interfaces: up to four gigabit Ethernet, two 32 bit PCI or PCI-X, as well as up to 8 x PCI-Express interfaces* can process even large volumes of data. In addition, two CAN-2.0B interfaces* as well as I²C and two serial interfaces are available as an option. The JTAG interface is also available as a debug interface. Another highlight of the MPC8548 is the double-precision FPU. The local bus is linked to the board-to-board connectors, as are all other essential CPU signals, and can be utilized for easy connection to other peripherals.

The TQM8548 was designed, as are all TQ modules, for hard use within an industrial environment: The small module measuring 100 x 75 mm is fitted throughout with longlife components that are designed to meet industrial requirements and also available within an expanded temperature range of –40°C to +85°C*. The mezzanine connectors of 0.8 mm pitch readily stand up to high-stress conditions and easily transfer data at a rate of 3 GHz – factors which all ensure years of reliable operation in the terminal equipment.

Other key features include longterm availability as well as scalability in terms of performance and memory expansion.

TQ-Components offers the Plug-and-Play starter kit STK8548 to facilitate fast and easy startup, and as an evaluation board. The Plug-and-Play principle enables you to begin with software development even if the actual target hardware is not yet available. As a result, a product can be brought to market both more quickly and at lower cost.
