| Overview |
| -------- |
| QorIQ LS1012A Reference Design System (LS1012ARDB) is a high-performance |
| development platform, with a complete debugging environment. |
| The LS1012ARDB board supports the QorIQ LS1012A processor and is |
| optimized to support the high-bandwidth DDR3L memory and |
| a full complement of high-speed SerDes ports. |

| SoC overview. |
| |
| LS1012ARDB board Overview |
| ----------------------- |
| - SERDES Connections, 4 lanes supporting: |
| - PCI Express - 3.0 |
| - SGMII, SGMII 2.5 |
| - SATA 3.0 |
| - DDR Controller |
| - 16-bit, 1 GB DDR3L SDRAM memory, running at data rates up to 1 GT/s |
| -QSPI: A dual 1:3 switch, NX3L4357GM,115 (U35) drives the QSPI chip-select |
| signals to |
| - QSPI NOR flash memory (2 virtual banks) |
| - the QSPI emulator.s |
| - USB 3.0 |
| - one high-speed USB 2.0/3.0 port. |
| - Two enhanced secure digital host controllers: |
| - SDHC1 controller can be connected to onboard SDHC connector |
| - SDHC2 controller: Three dual 1:4 mux/demux devices, |
| 74CBTLV3253DS (U30, U31, U33) drive the SDHC2 signals to eMMC, |
| SDIO WiFi, SPI, and Ardiuno shield |
| - 2 I2C controllers |
| - One SATA onboard connectors |
| - UART |
| - The LS1012A processor consists of two UART controllers, |
| out of which only UART1 is used on RDB. |
| - ARM JTAG support |
