DIL/NetPC DNP/2110: 64-pin DIL Connector Pinout

The mechanical interface between the DIL/NetPC DNP/2110 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), two serial interfaces (10 pins), 10BASE-T and 100-BASE-TX Ethernet interface (4 pins), general purpose parallel I/O (20 pins) and the I/O extension bus (26 pins).

Please Note: Some pins are called "Product Specific Pins (PSP)". Future versions of the DIL/NetPC will differ only with this pins from the DNP/2110. All other pins will have the same functions.

The DNP/2110 PIO port C pins (PC.0, PC.1, PC.2 and PC.3) offer as alternate function SPI mode operation. The DNP/2110 can act as SPI master or SPI slave device. In SPI master mode MOSI (PC.0) is an output, MISO (PC.1) is an input, SPICLK (PC.2) is an output and SPICS (PC.3) is an output. In SPI slave mode MOSI is an input, MISO is an output, SPICLK is an input and SPICS is an input.
