SBC for Embedded Networking in Harsh Environments: DIL/NetPC DNP/2110

The DIL/NetPC DNP/2110 provides a very compact Intel 400 MHz PXA255 Xscale-based low power embedded controller with TCP/IP stack and web server for high-speed embedded networking applications in a harsh environment. The DIL/NetPC offers the footprint of a standard 64-pin DIL socket with 2.54 mm centers (0.1 inch pin grid) and all the hardware and software features necessary to add high-speed networking capabilities to any product design. The DIL/NetPC was developed specifically for products that need to be connected to 10 or 100 Mbps Ethernet-based TCP/IP networks with minimum development costs.

DIL/NetPC DNP/2110

The DNP/2110 comes as ready-to-run embedded networking system for a operating temperature range from -40 C to +85 C (version with 0 C to +70 C also available). The use of the DNP/2110 will allow you to realize a substantial time and costs savings over other chip-based approaches. Currently, there is no other 10/100 Mbps 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 10/100 Mbps Ethernet, full TCP/IP and an embedded Web server or other TCP/IP-based server software is required.

DIL/NetPC

To interface the DNP/2110 with existing devices and equipment, the DNP/2110 offers two asynchronous serial RS232C interfaces with TTL levels and handshake signals (COM1/COM2 - 16550 compatible), 20-bit general purpose high-speed parallel I/Os and a 8-bit extension bus with interrupt inputs and chip select outputs. There are two ways for DNP/2110 integration: 1. Adapt the DNP/2110 to your existing product. Use the existing I/Os within your product to communicate with the DNP/2110. 2. Use the DNP/2110 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 DNP/2110 can be the main controller. Additional I/Os are driven by the 8-bit extension bus.

The on-board FLASH memory provides storage for the DNP/2110 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 DNP/2110 COM1 port or the 10/100 Mbps Ethernet interface for in-system programming. The DNP/2110 in-system programming was developed for OEM application software, operating system downloads (i.e. upgrade from embedded Linux to eCos) and data download and to make it easier to update the on-board FLASH content in the field.

DIL/NetPC DNP/2110: Description

The DNP/2110 is build around the Intel Xscale PXA255 32-bit RISC microcontroller running with 400 MHz. The PXA255 has a large instruction cache (I-Cache) and data cache (D-Cache), memory-management unit (MMU), and read/write buffers. The PXA255 offers high-performance processing power with up to 480 Dhrystone 2.1 MIPS. The PXA255 CPU core implements the ARM 5TE architecture as defined in the ARM Architecture Reference Manual with 32-bit ARM and 16-bit Thumb instruction set. The PXA255 provides a complete set of internal peripherals. There are multiple serial communication channels, general-purpose I/O ports, timers, interrupt control, reset control, and power management functions.

DNP/2110 Block Diagram

The external main components around the Intel Xscale PXA255 32-bit RISC microcontroller on the DNP/2110 are one FLASH chip with 16 MBytes, one 16 or 32 MByte SDRAM chip, and one 10/100 Mbps Ethernet LAN controller with 10BASE-T and 100BASE-TX physical layer interface. The FLASH stores the hardware setup code, the U-Boot boot loader, operating system, and OEM applications. The 32-bit SDRAM access and the refresh operation is driven by the PXA255 integrated SDRAM controller.

The DNP/2110 10/100 Mbps Ethernet controller is a SMSC LAN91C111 single chip MAC+PHY. This highly-integrated Ethernet LAN controller includes 8 KByte internal memory for receive and transmit FIFO buffers, an IEEE 802.3/802.3u Ethernet MAC engine, and internal 10BASE-T and 100BASE-TX transmit and receive filters. The SMSC LAN91C111 supports full-duplex switched Ethernet operations and auto negotiation for 10 and 100 Mbps. For the DNP/2110 LAN integration, the PHY interface needs only an external low-cost isolation transformer.

The mechanical interface between the DNP/2110 and existing devices and equipment is a JEDEC 64-pin DIL connector with 2.54 mm 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), 10/100 Mbps Ethernet interface (4 pins), general purpose parallel I/O (20 pins) and the extension bus (26 pins).

DIL/NetPC DNP/2110: Ordering Information

The DIL/NetPC DNP/2110 provides the dimensions of a standard JEDEC 64-pin DIL socket and will be delivered with a preinstalled embedded Linux operating system (kernel version 2.4), TCP/IP stack, thttpd embedded web server, FTP server for file transfers to and from the DNP/2110, and Telnet server for remote login via Ethernet. There is also the U-Boot boot loader preinstalled for update the operating system components (kernel and/or root file system) or download an other operating system image file to the on-board FLASH.

The module is based on an Intel Xscale PXA255 32-bit RISC microcontroller. This processor runs with 400 MHz clock. There are 16 or 32 MByte SDRAM and 16 MByte FLASH memory on-board. Two serial interfaces (COM1, COM2), 20 digital I/Os and one 8 bit expansion bus with four chip select output signals and five interrupt input signals offers the interface to higher level systems and devices by using the standard JEDEC 64-pin DIL interface with 2.54 mm centers. The network interface is made by a 10BASE-T/100BASE-TX Ethernet interface with embedded RAM for packet buffering and support for full-duplex operation and auto negotiation for 10 and 100 Mbps. The operating temperature range is: -40 C to +85 C (version with 0 C to +70 C also available).

As development support we offer two starterkits with DNP/2110, DNP/EVA2 evaluation board (special version - without the ST16C2550 dual uart and the uart support chips) or DNP/EVA6 evaluation board, 110-230 VAC to 5 VDC international power supply, nullmodem cable, CD-ROM, and user manual for the first steps. The CD-ROM comes with a full GNU cross tool chain for C/C++ software development. This binary files of the tool chain runs on a x86 Linux-based host (SuSE, Red Hat or other) and builds ELF binary files for the Intel Xscale PXA255 32-bit RISC microcontroller.
