Banks 0, 1, and 2 are connected for 2.5V I/O. Bank 3 is used for the 1.8V DDR2 component memory interface of Spartan-6 FPGA’s hard memory controller. The voltage applied to the FPGA I/O banks used by the SP601 board is summarized in Table 1-2.ReferencesSee the Spartan-6 FPGA documentation for more information at /support/documentation/spartan-6.htm .2. 128 MB DDR2 Component MemoryThere are 128MB of DDR2 memory available on the SP601 board. A 1-Gb ElpidaEDE1116ACBG (84-ball) DDR2 memory component is accessible through Bank 3 of the LX16 device. The Spartan-6 FPGA hard memory controller is used for data transfer across the DDR2 memory interface’s 16-bit data path using SSTL18 signaling. The SP601 board supports the “standard” VCCINT setting of 1.20V ± 5%. This setting provides the standard memory controller block (MCB) performance of 625Mb/s for DDR2 memory in a -2 speed grade device.

SPI x4 FlashThe Xilinx Spartan-6 FPGA hosts a SPI interface which is accessible to the Xilinx iMPACTconfiguration tool. The SPI memory device operates at 3.0V; the Spartan-6 FPGA I/Os are3.3V tolerant and provide electrically compatible logic levels to directly access the SPI flashthrough a 2.5V bank. The XC6SLX16-2CSG324 is a master device when accessing anexternal SPI flash memory device.The SP601 SPI interface has two parallel connected configuration options (see Figure1-4):an SPI X4 (Winbond W25Q64VSFIG) 64-Mb flash memory device and a flashprogramming header (J12). J12 supports a user-defined SPI mezzanine board. The SPIconfiguration source is selected via SPI select jumper J15. For details on configuring theFPGA, see 15.

The board supports a GMII/MII interface fromthe FPGA to the PHY. The PHY connection to a user-provided Ethernet cable is through aHalo HFJ11-1G01E RJ-45 connector with built-in magnetics.On power-up, or on reset, the PHY is configured to operate in GMII mode with PHYaddress 0b00111 using the settings shown in Table1-8. These settings can be overwrittenvia software commands passed over the MDIO interface.Table 1-8:PHY Configuration PinsPin Connection onBoardBit[2]Definition and ValueBit[1]Definition and ValueBit[0]Definition and ValueCFG0V CC 2.5V PHYADR[2] = 1PHYADR[1] = 1PHYADR[0] = 1 CFG1Ground ENA_PAUSE = 0PHYADR[4] = 0PHYADR[3] = 0 CFG2V CC 2.5V ANEG[3] = 1ANEG[2] = 1ANEG[1] = 1 CFG3V CC 2.5V ANEG[0] = 1ENA_XC = 1DIS_125 = 1 CFG4V CC 2.5V HWCFG_MD[2] = 1HWCFG_MD[1] = 1HWCFG_MD[0] = 1 CFG5V CC 2.5V DIS_FC = 1DIS_SLEEP = 1HWCFG_MD[3] = 1 CFG6PHY_LED_RX SEL_BDT = 0INT_POL = 175/50Ω = 0 Table 1-9:Ethernet PHY ConnectionsFPGA U1 Pin Schematic Net NameU3 M88E111Pin Number Pin NameP16PHY_MDIO33MDIO N14PHY_MDC35MDC J13PHY_INT32INT_B L13PHY_RESET36RESET_B M13PHY_CRS115CRS L14PHY_COL114COL L16PHY_RXCLK7RXCLK P17PHY_RXER8RXER N18PHY_RXCTL_RXDV4RXDV M14PHY_RXD03RXD0 U18PHY_RXD1128RXD1 U17PHY_RXD2126RXD2 T18PHY_RXD3125RXD3 T17PHY_RXD4124RXD4 N16PHY_RXD5123RXD5SP601 Hardware User GuideReferencesSee the Marvell Alaska Gigabit Ethernet Transceivers product page for more information.[Ref 16]Also, see the LogiCORE™ IP Tri-Mode Ethernet MAC User Guide .

USB-to-UART BridgeThe SP601 contains a Silicon Labs CP2103GM USB-to-UART bridge device (U4) which allows connection to a host computer with a USB cable. The USB cable is supplied in this evaluation kit (Type A end to host computer, Type Mini-B end to SP601 connector J9). Table 1-10 details the SP601 J9 pinout.Xilinx UART IP is expected to be implemented in the FPGA fabric. The FPGA supports the USB-to-UART bridge using four signal pins, transmit (TX), receive (RX), Request to Send (RTS), and Clear to Send (CTS).Silicon Labs provides royalty-free Virtual COM Port (VCP) drivers which permit the CP2103GM USB-to-UART bridge to appear as a COM port to host computercommunications application software (for example, HyperTerm or TeraTerm). The VCP device driver must be installed on the host PC prior to establishing communications with the SP601. Refer to the SP601 Getting Started Guide for driver installation instructions.ReferencesRefer to the Silicon Labs website for technical information on the CP2103GM and the VCP drivers.In addition, see some of the Xilinx UART IP specifications at:•/support/documentation/ip_documentation/xps_uartlite.pdf •/support/documentation/ip_documentation/xps_uart16550.pdfTable 1-10:USB Type B Pin Assignments and Signal DefinitionsUSB ConnectorPinSignal NameDescription1VBUS +5V from host system (not used)2USB_DATA_N Bidirectional differential serial data (N-side)3USB_DATA_P Bidirectional differential serial data (P-side)4GROUNDSignal groundTable 1-11:CP2103GM ConnectionsFPGA U1 PinUART Functionin FPGA Schematic Net Name U4 CP2103GMPinUART Function in CP2103GM U10RTS, output USB_1_CTS 22CTS, input T5CTS, input USB_1_RTS 23RTS, output L12TX, data out USB_1_RX 24RXD, data in K14RX, data inUSB_1_TX25TXD, data out。
