DIL/NetPC DNP/5282: 40-pin DIL Connector Pinout

The mechanical interface between the DIL/NetPC DNP/5282 and existing devices and equipment is a JEDEC 40-pin DIL connector with 2.54mm centers. This allows the direct integration to a standard 40-pin DIL socket. The 40 pins in total are used for 3.3 volt power supply (2 pins), Reset in and RCM (2 pins), two serial interfaces (10 pins), 10BASE-T and 100BASE-TX Ethernet interface (4 pins) and general purpose I/O (22 pins).

Please Note: Some pins are called "Product Specific GPIO Pins". Future versions of DIL/NetPCs with DIL-40 pinout will differ with this pins from the DNP/5282. All other pins will have the same functions. The DNP/5282 alternate functions (Pins 13, 14, 15, 16 and Pins 36, 37, 38, 39) are ColdFire-specific.
