SBC for Embedded Networking with Ethernet and VoIP Support: DIL/NetPC DNP/5370

The DIL/NetPC DNP/5370 provides a very compact Analog Devices BF537 32-bit Backfin-based low power embedded controller with TCP/IP stack, embedded VoIP (Voice-over IP) support, web server, Telnet server, TFTP client and FTP server for embedded networking with Ethernet and CAN connectivity in industrial and laboratory environments. The DNP/5370 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 which are necessary to add embedded networking capabilities to any product and system design. The DNP/5370 was developed specifically for embedded gateway and data logger applications that need to be connected to 10/100 Mbps Ethernet-based TCP/IP networks with minimum development costs.

The DNP/5370 comes as ready-to-run embedded networking system for Ethernet- and TCP/IP-based gateway applications. The use of the DNP/5370 will allow you to realize a substantial time and cost saving over other chip-based approaches. Currently, there is no other 32-bit embedded networking solution with pre-installed O/S, CAN, VoIP support, 10/100 Mbps Ethernet, full TCP/IP and more development time saving features on the market.

To interface the DNP/5370 with existing devices and equipment, the DNP/5370 offers two asynchronous serial RS232C ports with TTL levels (COM1 with handshake signals, COM2 only TxD and RxD), one SSI (Synchronous Serial Interface) with I2S support, one TWI (Two-wire Interface) with I2C support, one CAN (Controller Area Network) 2.0b interface, one 10/100 Mbps Ethernet LAN interface, 20-bit general purpose high-speed parallel I/Os and an 8-bit extension bus with interrupt input and chip select outputs. There are two ways for DNP/5370 integration: 1. Adapt the DNP/5370 to your existing product. Use the existing I/Os within your product to communicate with the DNP/5370. 2. Use the DNP/5370 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/5370 can be the main controller. Additional I/Os are driven by the 8-bit extension bus.

The on-board NOR and NAND FLASH memory provides storage for the DNP/5370 operating system with TCP/IP stack, embedded web server, and a web-based configuration interface as well as OEM applications and data. The NOR FLASH memory is in-system programmable over JTAG, serial and the Ethernet interface. The boot block of the NOR 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 also use a high-speed serial connection through the DNP/5370 COM1 port or the 10/100 Mbps Ethernet interface for in-system programming. The DNP/5370 in-system programming was developed for OEM application software, operating system downloads (i.e. upgrade the embedded Linux O/S), data download and to make it easier to update the on-board FLASH content in the field.
