DESCRIPTION

Central Processing Unit
The Motorola PowerPC MPC8548 series of processors deliver unmatched computing power with minimum power dissipation. This increases the reliability over a wide temperature range.

Memory

SDRAM
The board comes with up to 1GB of DDR2 SDRAM unit running at 1GHz. It is equipped with an Error Checking and Correction (ECC) mechanism providing a high degree of protection against errors. It is capable of detecting and correcting single errors while alerting when multiple errors arise. The ECC mechanism enhances the system reliability to a great extent.

NOR Flash and NAND Flash
The SBC includes 128 MB NOR flash and 8GB NAND flash that ensures sufficient memory resources for numerous applications.

Power Requirements
The SBC maybe configured to receive all its power from the Rear backplane +5.0V, auxiliary 3.3V supply and generate 1.0V, 1.1V, 1.2V, 1.5V, 1.8V, 2.5V, 3.3V using the on-board circuitry.

Timer

Real Time Clock
The SBC includes a Real Time Clock (RTC) for time and date keeping.

Watchdog Timer
The SBC provides an on-board hardware watchdog timer for programming the required time out interval after which it will reset the board.

I/O Interfaces

Ethernet Interface
The two-gigabit Ethernet interface ports support the standard 10 MB/s, fast 100 MB/s or gigabit 1000 MB/s Ethernet links. The physical interface is a 10BaseT/100BaseTx twisted pair.

UART Ports
The SBC provides standard serial UART ports with one configurable RS-232/422 interface and One RS-422 serial port.

LVDS I/O
The SBC is equipped with eight pairs user configurable LVDS I/O.
