| 4 | 1. Board Description |
| 5 | |
| 6 | The MPC837xE-RDB are reference boards featuring the Freescale MPC8377E, |
| 7 | MPC8378E, and the MPC8379E processors in a Mini-ITX form factor. |
| 8 | |
| 9 | The MPC837xE-RDB's have the following common features: |
| 10 | |
| 11 | A) 256-MBytes on-board DDR2 unbuffered SDRAM |
| 12 | B) 8-Mbytes NOR Flash |
| 13 | C) 32-MBytes NAND Flash |
| 14 | D) 1 Secure Digital High Speed Card (SDHC) Interface |
| 15 | E) 1 Gigabit Ethernet |
| 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 |
| 19 | I) 4-port USB 2.0 Hub |
| 20 | J) 1-port OTG USB |
| 21 | K) 2 serial ports (top main console) |
| 22 | L) on board Oscillator: 66M |
