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. |
Timers |
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. |
