• Internal AXI subsystem operating at up to 533MHz.
• Dual ARM HDLCD display controllers that support HDMI 1.4a up to 1080p.
• Dual DDR3L PHY and 32-bit DDR3L interfaces.
• PCIe Gen 2 4-lane root complex and PHY with coherent and non-coherent modes.
• Thin Links AXI master and slave interfaces to the LogicTile site. At the default clock frequency of
61.5MHz, the operating speeds are:
— Master interface: 68MBps in the forward direction and 78MBps in the reverse direction.
— Slave interface: 246MBps in the forward direction and 305MBps in the reverse direction.
Note
◦ The forward direction is from master to slave and the reverse direction is from slave to master.
◦ Expansion AXI over Thin Links provides a 256MB window.
• USB 2.0 host controller. This is a 480Mbps ULPI interface to off-chip PHY.
• PL354
Static Memory Controller
(SMC).
• PL330
Direct Memory Access
(DMA) controller.
• CoreSight processor debug (P-JTAG) and trace.
• APB subsystem:
— Dual-UART.
— I

S 4-channel stereo audio.
—
Power, Voltage, and Temperature
(PVT) monitoring of Juno r2 ARM Development Platform SoC.
— Non-volatile counter. A real time clock that retains its stored value after powerdown.
—
System Control Processor
(SCP). This is a Cortex-M3 processor integrated into the Juno r2 SoC.
It initiates the system architecture and pre-loads memory at powerup and performs power
management and system control functions during runtime.
— I
