  • Page 7: Static Memory Subsystem (Serial Flash Memory)

    UM1499 Functional description Signal termination A parallel termination is added on the clock lines to compensate, if needed, for the layout dissymmetry. Two 100k ohm resistors are used for each line in order to obtain an impedance of 50 ohms. All the other terminations are directly inside the pads (both on the SPEAr320S MPU and the memory sides).

  • Page 8: Serial Interface

    Functional description UM1499 Serial interface One serial interface port is available. Typically used as an OS monitor, this port is available on the J17 connector. It is possible to simulate a cross cable by changing the position of the J22 jumpers. Figure 3.
