| 2 | -------- |
| 3 | QorIQ LS1012A Reference Design System (LS1012ARDB) is a high-performance |
| 4 | development platform, with a complete debugging environment. |
| 5 | The LS1012ARDB board supports the QorIQ LS1012A processor and is |
| 6 | optimized to support the high-bandwidth DDR3L memory and |
| 7 | a full complement of high-speed SerDes ports. |

| 14 | LS1012ARDB board Overview |
| 15 | ----------------------- |
| 16 | - SERDES Connections, 4 lanes supporting: |
| 17 | - PCI Express - 3.0 |
| 18 | - SGMII, SGMII 2.5 |
| 19 | - SATA 3.0 |
| 20 | - DDR Controller |
| 21 | - 16-bit, 1 GB DDR3L SDRAM memory, running at data rates up to 1 GT/s |
| 22 | -QSPI: A dual 1:3 switch, NX3L4357GM,115 (U35) drives the QSPI chip-select |
| 23 | signals to |
| 24 | - QSPI NOR flash memory (2 virtual banks) |
| 25 | - the QSPI emulator.s |
| 26 | - USB 3.0 |
| 27 | - one high-speed USB 2.0/3.0 port. |
| 28 | - Two enhanced secure digital host controllers: |
| 29 | - SDHC1 controller can be connected to onboard SDHC connector |
| 30 | - SDHC2 controller: Three dual 1:4 mux/demux devices, |
| 31 | 74CBTLV3253DS (U30, U31, U33) drive the SDHC2 signals to eMMC, |
| 32 | SDIO WiFi, SPI, and Ardiuno shield |
| 33 | - 2 I2C controllers |
| 34 | - One SATA onboard connectors |
| 35 | - UART |
| 36 | - The LS1012A processor consists of two UART controllers, |
| 37 | out of which only UART1 is used on RDB. |
| 38 | - ARM JTAG support |
