SBCs for Embedded Networking: DIL/NetPC DNP/1486-3V

Please note: The DIL/NetPC DNP/1486 is in an end-of-life (EOL) state. For more information about availability and the DIL/NetPC PLM (Product Lifecycle Management) please contact

The DIL/NetPC DNP/1486 provides a very compact 32-bit 486 low power embedded PC solution with TCP/IP protocol stack, socket-based API and web server for embedded networking applications. The DIL/NetPC DNP/1486 offers the footprint of a standard 64-pin DIL socket with 2.54mm centers and all the hardware and software features necessary to add networking capabilities to any product design. The DIL/NetPC DNP/1486 was developed specifically for products that need to be connected to Ethernet-based networks with minimum development costs.

DIL/NetPC DNP/1486

The DIL/NetPC DNP/1486 is a ready-to-run embedded networking system. The use of the DIL/NetPC DNP/1486 will allow you to realize a substantial time and costs savings over other chip-based approaches. Currently, there is no other Ethernet- and TCP/IP-based embedded networking solution with more development time savings on the market. There is also no faster Time-to-Market for your product with lower costs if Ethernet, TCP/IP and an embedded web server is required.


To interface the DIL/NetPC DNP/1486 with existing devices and equipment, the DIL/NetPC DNP/1486 offers a asynchronous serial RS232C interface with TTL levels and all handshake signals (COM1 - 16550 compatible), 20-bit general purpose parallel I/Os and a 8-bit I/O extension bus with programmable interrupts. There are two ways for DIL/NetPC DNP/1486 integration: 1.) Adapt the DIL/NetPC DNP/1486 to your existing product. Use the existing I/Os within your product to communicate with the DIL/NetPC DNP/1486. 2.) Use the DIL/NetPC DNP/1486 to control and monitor the hardware of your existing product. This might enable you to replace your existing controller entirely. In a new product design, the DIL/NetPC DNP/1486 can be the main controller. Additional I/Os are driven by the 8-bit I/O extension bus.

The on-board FLASH memory provides storage for the DIL/NetPC DNP/1486 operating system with TCP/IP stack and embedded web server as well as OEM applications and data. The FLASH memory is in-system programmable over JTAG, serial and the Ethernet interface. The boot block of the FLASH memory is only in-system programmable over the JTAG interface through a special cable attached to a PC parallel port. For all other FLASH blocks, you can use also a high-speed serial connection through the DIL/NetPC DNP/1486 COM1 port or the 10BASE-T Ethernet interface for in-system programming. The DIL/NetPC DNP/1486 in-system programming was developed for OEM application software and data download and to make it easier to update the on-board FLASH content in the field.

DIL/NetPC DNP/1486-3V: Description

The DIL/NetPC (DNP/1486-3V) is build around the 3 volt low power AMD Elan SC410 32-bit microcontroller. The AMD SC410 provides a 32-bit AM486 CPU with a complete set of PC/AT-compatible peripherals, along with the power management features required for low-power operation and a ISA bus interface for external ISA peripherals. The SC410 also provides all of the support functions found in the original IBM PC/AT. The SC410 microcontroller use the industry-standard 486 instruction set. All software and embedded operating systems written for the x86 architecture family is compatible with the SC410 and the DIL/NetPC DNP/1486.

DIL/NetPC Block Diagram

The external main components around the AMD Elan SC410 32-bit microcontroller on the DIL/NetPC (DNP/1486-3V) are one FLASH chip with 2 MBytes for the operating system and OEM applications, one 8 MByte DRAM chip and one 10 Mbps Ethernet LAN controller with 10BASE-T interface. The DRAM access and the refresh operation is driven by the SC410 integrated DRAM controller. The SC410 interface to the Ethernet controller is based on the SC410 ISA bus interface. The Ethernet controller is a external ISA peripheral in the SC410 ISA address space.

The DIL/NetPC (DNP/1486-3V) Ethernet controller is a Crystal CS8900 16-bit LAN controller chip. This highly-integrated Ethernet LAN controller includes on-chip buffer memory RAM, a 802.3 Ethernet MAC engine, 10BASE-T transmit and receive filters and a direct ISA bus-based interface to the AMD Elan SC410 32-bit microcontroller. The CS8900 Ethernet Media Access Control (MAC) engine is fully compliant with the IEEE 802.3 Ethernet standard (ISO/IEC 8802-3, 1993) and supports full-duplex operation. For the DIL/NetPC DNP/1486 LAN integration, the 10BASE-T interface needs a external low-cost isolation transformer.

The mechanical interface between the DIL/NetPC DNP/1486 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). The 28 pins for the I/O extension bus are called "Product Specific Pins (PSP)". Future versions of the DIL/NetPC DNP/1486 will differ only with this 28 pins from the DNP/1486-3V.

DIL/NetPC DNP/1486-3V: Ordering Information

The DIL/NetPC DNP/1486-3V provides the dimensions of a standard 64-pin JEDEC DIL socket and will be delivered with a preinstalled Datalight ROM-DOS 6.22, Datalight´s FLASH File System FlashFX, Datalight´s TCP/IP stack with a powerful API and a Web server for embedded networking applications. A DOS FTP server and an Email Alerter are optionaly available. There is also a preinstalled embedded Linux (kernel version 2.2 or 2.4) operating system with full TCP/IP, thttpd embedded Web server, FTP server, and Telnet server available.

The module is based on a 32-bit AMD Low Power 486 SX processor with a complete embedded PC/AT- architecture (AMD Elan SC410). This processor runs with 33 MHz clock. Versions with 66 and 100 MHz are available on request. There are 8 MByte DRAM and 2 MByte FLASH memory on-board. One serial interface (COM1), 20 digital I/Os and one expansion bus with programmable chip select signals and interrupt inputs offers the interface to higher level systems and devices by using the 64-pin DIL interface with 2.54mm centers. The network interface is made by a 10BASE-T Ethernet interface with embedded RAM for packet buffering and support for full-duplex operation.

As development support we offer a starterkit with various DOS libraries which can be integrated in the Borland C/C++ development environment to build own TCP/IP- based embedded networking applications. For Linux developers we offer support and documentation, which can be used together with the GNU tool chain.
