3.2.10.6 HSIC
High-Speed Inter-Chip (HSIC) is a standard for USB chip-to-chip interconnect with a 2-signal (strobe,
data) source synchronous serial interface using 240 MHz DDR signaling to provide only high-speed 480
Mbps data rate.
The interface operates at high speed, 480 Mbps, and is fully compatible with existing USB software
stacks. It meets all data transfer needs through a single unified USB software stack.
The HSIC interface is not used on the board and is connected to two-point jumper J5 (not mounted).

LCD TFT Interface
This section describes the signals and connectors related to the LCD interface.
3.3.1.1
LCD Interface
The SAMA5D2-PTC-EK board provides a connector with 18 bits of data and control signals to the LCD
interface. Other signals are used to control the LCD and are available on connector J16: TWI, SPI, two
GPIOs for interrupt, 1-wire and power supply lines.
This connector is used to connect LCD display series 43xx or 70xx from PDA.

LCD Expansion Header
J16 is a 1.27-mm pitch, 50-pin header. It gives access to the LCD signals.
