1 Freescale MPC837xEMDS Board
2 -----------------------------------------
6 The MPC837xE-RDB are reference boards featuring the Freescale MPC8377E,
7 MPC8378E, and the MPC8379E processors in a Mini-ITX form factor.
9 The MPC837xE-RDB's have the following common features:
11 A) 256-MBytes on-board DDR2 unbuffered SDRAM
13 C) 32-MBytes NAND Flash
14 D) 1 Secure Digital High Speed Card (SDHC) Interface
16 F) 5-port Ethernet switch (Vitesse 7385)
17 G) 1 32-bit, 3.3 V, PCI slot
18 H) 1 32-bit, 3.3 V, Mini-PCI slot
21 K) 2 serial ports (top main console)
22 L) on board Oscillator: 66M
24 The MPC837xE-RDB's have the following differences:
