|
|
1. Board Description
|
||
|
|
|
||
|
|
The MPC837xE-RDB are reference boards featuring the Freescale MPC8377E,
|
||
|
|
MPC8378E, and the MPC8379E processors in a Mini-ITX form factor.
|
||
|
|
|
||
|
|
The MPC837xE-RDB's have the following common features:
|
||
|
|
|
||
|
|
A) 256-MBytes on-board DDR2 unbuffered SDRAM
|
||
|
|
B) 8-Mbytes NOR Flash
|
||
|
|
C) 32-MBytes NAND Flash
|
||
|
|
D) 1 Secure Digital High Speed Card (SDHC) Interface
|
||
|
|
E) 1 Gigabit Ethernet
|
||
|
|
F) 5-port Ethernet switch (Vitesse 7385)
|
||
|
|
G) 1 32-bit, 3.3 V, PCI slot
|
||
|
|
H) 1 32-bit, 3.3 V, Mini-PCI slot
|
||
|
|
I) 4-port USB 2.0 Hub
|
||
|
|
J) 1-port OTG USB
|
||
|
|
K) 2 serial ports (top main console)
|
||
|
|
L) on board Oscillator: 66M
|
||
|
|
|
||
|
|
The MPC837xE-RDB's have the following differences:
|
||
|
