DIL/NetPC DNP/1486-3V: 64-pin DIL Connector Pinout

The mechanical interface between the DIL/NetPC and existing devices and equipment is a JEDEC 64-pin DIL connector with 2.54mm centers. This allows the direct integration to a standard 64-pin DIL socket. The 64 pins in total are used for 3.3 volt power supply (2 pins), Reset in and out (2 pins), serial interface (8 pins), 10BASE-T Ethernet interface (4 pins), general purpose parallel I/O (20 pins) and the I/O extension bus (28 pins).
