4. Interfaces and external signals

  • Ethernet 10/100 Mbit MAC

  • Dual USB 2.0 Full Speed (12 MBit/s) Hosts

  • USB 2.0 Full Speed (12 MBit/s) Device

  • Three USARTs

  • One UART

  • One Synchronous Serial Controller (SSC, I2S)

  • Two Serial Peripheral Interfaces (SPI)

  • One Two Wire Interface (TWI, I2C)

  • One MultiMedia Card Interfaces

  • JTAG debug port

  • Digital Ports - up to 39 available

  • Control Signals: IRQs, BMS, SHDN, WKUP

  • 4 Programmable Clocks

Some of the various functions are realized by multiplexing connector pins; therefore not all functions may be used at the same time (see Appendix D, Panel-Card Pin Assignment)).
