UM1499 User manual EVALSP320SCPU evaluation board for SPEAr320S Introduction This document applies to revision 2.0 SPEAr320S CPU evaluation boards. This board can be used to evaluate SPEAr320S microprocessors; the evaluation board kit comprises one board, one serial cable interface, and one power supply.
Connect a serial cable from connector J17 (serial link) to a host PC. On the host PC running Windows or Linux, start the Terminal program. Connect the +5 V voltage adapter (supplied in the EVALSP320SCPU package) to the J11 power voltage connector on the CPU board.
Functional description UM1499 Functional description The following figure shows the block diagram of the EVALSP320SCPU board. Figure 2. EVALSP320SCPU board block diagram Expansion connector bottom side NOR Flash DDR2 Serial I/F Power supply USB 2.0 Host 1 SPEAr320S USB 2.0...
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).
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.
UM1499 Expansion connectors Expansion connectors The CPU board has two 86-pin connectors (J12 and J13) that are used to extend the board. On the board the connectors are horizontally center-aligned, and the distance between the mechanical holes is 3400.00 th. Table 2 lists connector J12 pins.
