3. Interfaces and external signals

  • 2x 100-pin fine-pitch low-profile Connectors (Hirose FX8)

  • Ethernet 10/100 Mbit MAC

  • USB 2.0 High Speed Host

  • USB 2.0 Full Speed OTG (USB-On-the-Go)

  • USB 2.0 High Speed Device

  • Four USARTs

  • One UART

  • One Synchronous Serial Controller (SSC, I2S)

  • One Serial Peripheral Interface (SPI)

  • Two Two Wire Interface (TWI, I2C)

  • One High Speed MultiMedia Card Interface

  • Three PWM

  • 4-wire Touch Controller

  • AC'97 Sound Controller

  • LCD/TFT Controller (1280 x 860 pixels)

  • JTAG debug port

  • Digital Ports - up to 100 available

  • Control Signals: IRQs, BMS, SHDN, WKUP

  • Two Programmable Clocks

  • Image Sensor Interface

  • Analog-to-Digital Converter

  • 16-Bit parallel CPU-Bus

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, Stamp9G45 Pin Assignment)).
