DNP ARM Embedded Module with Linux

The DIL/NetPC DNP/9200 with Arm 9 Embedded Module is single board computer (SBC) based on a 180 MHz AT91RM9200 ARM9-based low power embedded controller with USB support, TCP/IP stack, web server, Telnet server, (T)FTP support for embedded networking with Ethernet and USB connectivity in industrial and laboratory environments. This SBC runs Linux and the DNP/9200 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 embedded networking capabilities to any product design. The DNP/9200 Arm 9 Embedded Module was developed specifically for products that need to be connected to 10/100 Mbps Ethernet-based TCP/IP networks and USB devices (Gateway Applications) with minimum development costs.

The DNP/9200 Arm 9 Embedded Module comes as ready-to-run embedded networking system for Ethernet und USB host/device gateway applications. The use of the DNP/9200 Arm 9 Embedded Module will allow you to realize a substantial time and costs savings over other chip-based approaches. Currently, there is no other embedded networking solution like the Arm 9 Embedded Module we have that comes with pre-installed O/S, USB host/device, 10/100 Mbps Ethernet- and TCP/IP-based and more development time savings features on the market. There is also no faster Time-to-Market for your product with lower costs if USB host/device, 10/100 Mbps Ethernet, full TCP/IP and a Arm 9 Embedded Module Web server or other TCP/IP-based server software is required for the Arm 9 Embedded Module.

SBC Details - Arm 9 Embedded Module

To interface the DNP/9200 with Arm 9 Embedded Module with existing devices and equipment, the DNP/9200 with Arm 9 Embedded Module offers two asynchronous serial RS232C ports with TTL levels (COM1 with handshake signals, COM2 only TxD and RxD), one USB device port, one USB host port (compliance with USB 2.0 full-speed and low-speed specification), one 10/100 Mbps Ethernet interface, 20-bit general purpose high-speed parallel I/Os and a 8-bit extension bus with interrupt input and chip select outputs. There are two ways for DNP/9200 Arm 9 Embedded Module integration: 1. Adapt the DNP/9200 to your existing product. Use the existing I/Os within your product to communicate with the DNP/9200. 2. Use the DNP/9200 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/9200 Arm 9 Embedded Module 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/9200 Arm 9 Embedded Module operating system with USB driver code, 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/9200 Arm 9 Embedded Module COM1 port or the 10/100 Mbps Ethernet interface for in-system programming. The DNP/9200 in-system programming was developed for OEM application software, operating system downloads (i.e. upgrade the embedded Linux O/S) and data download and to make it easier to update the on-board FLASH content in the field.
