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.

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
