    (SMT) connectors (0.635 mm) lining two sides of the module (referred to as phyCORE-connector). This allows the phyCORE-SC520 to be plugged into any target application like a “big chip”. A new numbering scheme for the pins on the phyCORE-connector has been introduced with the phyCORE specifications.
  • Page 16 Development Board/user target circuitry. The upper left-hand corner of the numbered matrix (pin 1A) is thus covered with the corner of the phyCORE-SC520 marked with a white triangle. The numbering scheme is always in relation to the PCB as viewed from above, even if all connector contacts extend to the bottom of the module.

  • Page 26: Supply Voltage

    2.1 Supply Voltage The phyCORE-SC520 requires up to three separate supply voltages depending on the level of expansion. These are 2.5 V for the core voltage of the processor, 3.3 V for the I/O voltage of the processor and, if the SIO device (Serial Input/Output device) is connected, an additional 5 V supply.

  • Page 27: Table 3: Current Draw

  • Page 34: Ide Interface

    In addition to the ISA bus signals, two Chip Select signals IDE_CS0 and ICE_CS1 are available for establishing a hard drive connection. If the length of the cable between the phyCORE-SC520 and the IDE device is more than 100 mm we recommend connecting bus drivers to the data lines in order to reduce EMI radiation.

  • Page 35: Ethernet Connector

    Pin Description Ethernet Connector If the optional Ethernet controller RT8139 from Realtec populates the phyCORE-SC520 and a network connection needs to be enabled, a YCL 20PMT04 transmitter must be connected. Example circuitry for connection can be found in section 7.9.

  • Page 36: Isa Bus

    In this case the applicable address lines must be switched to 5 V over a unidirectional transceiver. Caution: Do not simply connect pull-up resistors to the address lines! This would cause destruction of the SC520 controller since the address outputs are not 5 V tolerant! © PHYTEC Meßtechnik GmbH 2002 L-554e_2...

  • Page 47: System-Bios

    All BIOS interrupts available on desktop PC‘s (or compatible machines) are supported. The phyCORE-SC520 is populated with Flash memory in which the System-BIOS (128 kByte) as well as the image of the Flash drive is accommodated.

  • Page 48: Cmos Setup

    System-BIOS. This COMS setup is invoked if the <DEL> key is pressed during the memory test immediately after the phyCORE-SC520 is powered on or reset. If the input/output is redirected to the serial interface COM1 (no graphic card present), then the key combination ^C (STRG+C) must be used on a terminal program on the connected PC.

  • Page 49: Flash Disk

    Flash memory device. For example; 917 kByte if a 1 MB Flash device is installed. If a larger Flash populates the phyCORE-SC520 it is possible to set up multiple Flash disks. If the Flash disk is intended to be used as Boot option, drive A: must be set as the first boot selection.

  • Page 50: Manufacturing Mode

    Manufacturing Mode The manufacturing mode is an operating mode made available by the System-BIOS that allows the user to access the phyCORE-SC520 and its on-board Flash device over a serial interface. This requires that a host-PC must be connected with the module’s COM1 interface via a serial interface cable.
  • Page 51 The baud rate used by the phyCORE-SC520 in manufacturing mode is set at 38,400 baud and can not be changed. Only the first two serial interfaces COM1 and COM2 are supported by the device driver.
  • Page 52 The procedure described above result that Drive A: of the phyCORE-SC520 can be addressed under the letter D: on the host-PC and that Drive C: of the phyCORE-SC520 can be addressed under the letter E: on the host-PC. © PHYTEC Meßtechnik GmbH 2002...

    (boot block bottom type) or at the end (boot block top type) of the device. Boot block top Flash types are populated on the phyCORE-SC520. The sector addresses and sizes depend on this type. The Flash device can be found on the top side of the module, above the processor next to the two RAM devices.
  • Page 54 With the program Flashprg.exe every sector of the Flash device can be erased and overwritten, including the BIOS sectors! Should the BIOS be erased, there is no possibility of restoring it and it is necessary to return the phyCORE-SC520 for repair. © PHYTEC Meßtechnik GmbH 2002 L-554e_2...
  • Page 55 System Bios In order to work with the program Flashprg.exe the following steps are required: The phyCORE-SC520 must be booted in Manufacturing Mode first (RSTLD1=1, refer to section 4.4). Now the communication with the host-PC can be established via the corresponding interface.
