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

Please note: The DIL/NetPC ADNP/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 ADNP/1486 is a upgrade to the DNP/1486. This DIL/NetPC offers a footprint of a 128-pin QIL (Quad-In-Line) socket with 2.54mm centers. The inner 64 pins are compatible to the DIL/NetPC DNP/1486. The outer 64 pins offers a 16-bit ISA expansion bus. The DIL/NetPC ADNP/1486 was developed specifically for products that need to be connected to Ethernet-based networks with minimum development costs.


The ADNP/1486 is a ready-to-run embedded networking system. The use of the ADNP/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, full TCP/IP and an embedded Web server or other TCP/IP-based server software is required.


To interface the ADNP/1486 with existing devices and equipment, the ADNP/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 16-bit ISA extension bus with programmable interrupt inputs and programmable chip select outputs. There are two ways for ADNP/1486 integration: 1.) Adapt the ADNP/1486 to your existing product. Use the existing I/Os within your product to communicate with the ADNP/1486. 2.) Use the ADNP/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 ADNP/1486 can be the main controller. Additional I/Os or memory-based interfaces are driven by the 16-bit ISA extension bus.

The on-board FLASH memory provides storage for the ADNP/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 ADNP/1486 COM1 port or the 10BASE-T Ethernet interface for in-system programming. The ADNP/1486 in-system programming was developed for OEM application software, operating system downloads (i.e. upgrade from DOS to embedded Linux) and data download and to make it easier to update the on-board FLASH content in the field.

DIL/NetPC ADNP/1486-3V: Description

The DIL/NetPC (ADNP/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 ADNP/1486-3V.

ADNP/1486 Block Diagram

The external main components around the AMD Elan SC410 32-bit microcontroller on the ADNP/1486-3V are two FLASH chips with together 4 MBytes for the operating system and OEM applications, two 8 MByte DRAM chips (total DRAM size is 16 MByte) 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 ADNP/1486-3V also offers a IDE interface for CompactFlash devices or other standard IDE devices. The chip selects for this interface are driven by the IDE GAL in the ADNP/1486-3V block diagram.

The ADNP/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 ADNP/1486-3V LAN integration, the 10BASE-T interface needs a external low-cost isolation transformer.

The mechanical interface between the DIL/NetPC and existing devices and equipment is a 128-pin QIL connector with 2.54mm centers. This allows the direct integration to a 128-pin QIL socket. The inner 64 pins are compatible to the DIL/NetPC DNP/1486. The outer 64 pins offers a 16-bit ISA expansion bus.

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

The DIL/NetPC ADNP/1486-3V provides the dimensions of a 128-pin QIL 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 100 MHz clock. There are 16 MByte DRAM and 4 MByte FLASH memory on-board. One serial interface (COM1), 20 digital I/Os and one ISA expansion bus with programmable chip select signals and interrupt inputs offers the interface to higher level systems and devices by using the 128-pin QIL 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.
