NXP Semiconductors Layerscape® LS1028A Reference Design Board

NXP Semiconductors Layerscape^® LS1028A Reference Design Board (LS1028ARDB) is designed to enable evaluation and demonstration of the QorIQ^® Layerscape LS1028A Industrial Applications Processor. The LS1028A Reference Design Board supports most of the capabilities of the LS1028A SoC, and it can be used as a platform for software development and as a debug tool.

The LS1028ARDB Reference Design Board supports two active m.2 slots that can support a combination of PCIe or SATA interfaces, a full-size SD card slot, two USB 3.0 ports, and a DisplayPort interface. In addition, there are 5 TSN-enabled Gb Ethernet ports that are connected to the 4-port Ethernet switch and independent Ethernet controller on the LS1028A. The LS1028ARDB is expandable, featuring two mikroBUS™ sockets that can be used to add a variety of low-speed peripherals, such as GPS, NFC, BLE, ZigBee, or Thread connectivity.

The LS1028ARDB is powered by an MC34VR500 High-Performance Multi-output Buck Regulator. The high-frequency operation of the MC34VR500, coupled with high integration, enables an extremely small footprint solution. The output voltages and power-up sequencing are programmed to power most of the LS1028A rails as well as DDR3L/DDR4 memory, which significantly reduces development time.

NXP Semiconductors LS1028ARDB is pre-loaded with the Layerscape SDK (Software Development Kit). The SDK includes a 64-bit SMP Linux kernel, switchdev support for the integrated L2 switch, TSN configuration tools, U-boot, the GCC toolchain, and virtualization support. In addition, developers can take advantage of Ubuntu precompiled packages for Arm processors, greatly reducing development time for advanced applications.
