| 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: | |
