Overview

    Rakun LS1 system IP block is small foot-print, verified and proven building block consisting of CPU and memory subsystem for easy and inexpensive integration. Complete platform with hardware, Intelectual Property (IP), software and design support.

    It is pre-designed and based on NXP’s LS1021A processor, member of the QorIQ Layerscape 1 family. It features up to 5000 CoreMarks of CPU power, 1GB DDR3L memory with ECC, 1GB NAND Flash memory, 10/100/1000 Ethernet PHY, 4 6Gb/s SerDes Lanes used for SGMII/PCIe/SATA, PWM channels, CAN bus, UARTs etc.

    It is available in the form of PCB layout segment that can be easily integrated into customer specific board. It offers a lot of interfaces, used in telecom and industrial applications. Customization of the system is also available even for smaller quantities.

    It runs Linux operating system.

    Connectivity & Peripherals

    Ethernet Interfaces

    • Up to three 10/100/1000 Mbps Ethernet ports, one with PHY AR8033, others are available as SGMII, shared with PCIe lanes. IEEE 1588 precision clock synchronization.

    USB Interface

    • USB 3.0 Interface with PHY or USB 2.0 OTG interface with PHY.

    SerDes (PCIe/SATA/SGMII)

    • Four SerDes lanes are available. They can be used as as single PCIe x4, dual PCIe x1/2, dual SGMII, single SATA. Availability depends on CPU pinmuxing. SATA 3.0 (up to 6Gb/s) interface.

    Other available interfaces

    CPU’s ports offer a plethora of slower interfaces on its ports thru pinmuxing mechanism. This means that they are not available simultaneously, but are used depending on the application. List of available interfaces:

    • Two full featured UARTs with hardware handshaking (16450/16650 compatible) or four standard UARTs without hardware handshaking (Null-modem). Two additional full featured UARTs with hardware handshaking on QE. PROFIBUS is supported.
    • Six Low Power UARTs
    • Four CAN interfaces.
    • Two HDLC interfaces (Synchronous or asynchronous).
    • Two TDM interfaces with up to 128 channels, each running at 64Kbps.
    • Three l2C buses.
    • SPI interface. QuadSPI interface used for boot flash.
    • ESDHC/MMC/eMMC interface
    • PWM channels.
    • I2S, S/PDIF interfaces
    • GPIOs
    • Display controller unit (2D-ACE) 24-bit RGB (12-bit DDR pin interface), up to 2032×2047 pixels max.
    • HDMI transmitter
    Other

    Power Supply
