Freescale MPC837xE-RDB Board
|
|
-----------------------------------------
|
|
|
|
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:
|
|
|
|
MPC8377E-RDB MPC8378E-RDB MPC8379E-RDB
|
|
SATA controllers 2 0 4
|
|
PCI-Express (mini) 2 2 0
|
|
SGMII Ports 0 2 0
