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).

Please Note: The 28 pins for the I/O extension bus are called "Product Specific Pins (PSP)". Future versions of the DIL/NetPC will differ only with this 28 pins from the DNP/1486-3V. All other pins will have the same functions.
It is to be considered, however, that the DIL/NetPC DNP/1486-3V is a 3.3 volt- based system. The output levels are derived from the 3.3 volt supply voltage. Not all inputs of the DIL/NetPC DNP/1486-3V can be driven by external 5 volt components. For more details, see the following table.
