T2080PCIe-RDB is a Freescale Reference Design Board that hosts the T2080 SoC. It works in two mode: standalone mode and PCIe endpoint mode. T2080PCIe-RDB Feature Overview ------------------------------ Processor: - T2080 SoC integrating four 64-bit dual-threads e6500 cores up to 1.8GHz DDR Memory: - Single memory controller capable of supporting DDR3 and DDR3-LP devices - 72bit 4GB DDR3-LP SODIMM in slot Ethernet interfaces: - Two 10M/100M/1G RGMII ports on-board - Two 10Gbps SFP+ ports on-board - Two 10Gbps Base-T ports on-board Accelerator: - DPAA components consist of FMan, BMan, QMan, PME, DCE and SEC SerDes 16 lanes configuration: - SerDes-1 Lane A-B: to two 10G XFI fiber (MAC9 & MAC10) - SerDes-1 Lane C-D: to two 10G Base-T (MAC1 & MAC2) - SerDes-1 Lane E-H: to PCIe Goldfinger (PCIe4 x4, Gen3) - SerDes-2 Lane A-D: to PCIe Slot (PCIe1 x4, Gen2) - SerDes-2 Lane E-F: to C293 secure co-processor (PCIe2 x2) - SerDes-2 Lane G-H: to SATA1 & SATA2 IFC/Local Bus: - NOR: 128MB 16-bit NOR flash - NAND: 512MB 8-bit NAND flash - CPLD: for system controlling with programable header on-board eSPI: - 64MB N25Q512 SPI flash USB: - Two USB2.0 ports with internal PHY (both Type-A) PCIe: - One PCIe x4 gold-finger - One PCIe x4 connector - One PCIe x2 end-point device (C293 Crypto co-processor) SATA: - Two SATA 2.0 ports on-board SDHC: - support a TF-card on-board I2C: - Four I2C controllers. UART: - Dual 4-pins UART serial ports Signed-off-by: Shengzhou Liu <Shengzhou.Liu@freescale.com> Reviewed-by: York Sun <yorksun@freescale.com>
