• Flash Memory
  MX 25L6405MC-20G serial flash, with a 50MHz SPI bus and 64Mbit capacity (8MByte), in 300mil SO16 format. SPI, slower than a parallel bus, potentially allows for adding additional memory devices to the bus.
  The flash memory is typically used with two different filesystems. I.e.: Squashfs, a compressed read-only filesystem for Linux and JFFS2, a log-structured file system designed for use on flash devices in embedded systems.
• SDRAM
  Hynix hy57V561620F synchronous DRAM, 256Mbit organized in 16bit blocks, resulting in 32MByte.
• Ethernet (RJ45 socket)
  Ethernet controller (Marvell 88E6060) with two PHY (LFE8505).
• USB 2.0 Host Controller
  The NEC PD720102 open host controller interface works up to 480 Mbps.
• Wireless IEEE 802.11b / 802.11g (up to 54 Mbps)
  Atheros AR2315 single-chip WiFi processor running at 40 MHz.
  Integrated 32-bit MIPS R4000-class processor running at 183.5 MHz
• Interfacing
  Serial (RS-232)
  Connecting the Fonera's serial port to a PC requires an TTL to RS-232 level shifter converting +3.3V and 0V to +12V and -12V.
  There is also a JTAG port on the PCB but ports pins are omitted. Fonera - JTAG connector
