32-Bit 486 Provides Solution For Embedded Networking Applications
Designers looking for a low-power embedded PC solution can turn to the DIL/NetPC DNP/1486-3V. This compact 32-bit 486 comes with a TCP/IP stack and web server for embedded networking applications. It also matches a standard 64-pin DIL socket's footprint with 2.54-mm centers. All of the hardware and software features necessary for adding networking capabilities to any product design are included as well.

An asynchronous serial RS-232C interface lets designers interface the DIL/NetPC DNP/1486-3V with existing devices and equipment. This interface includes TTL levels and all handshake signals (COM1-16550 compatible), 20-bit general-purpose parallel I/Os, and an 8-bit I/O extension bus with programmable interrupts.

On-board flash memory provides storage for the DIL/NetPC 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, RS-232 serial, and the Ethernet interface. Its boot block is only in-system programmable over the JTAG interface through a special cable attached to a PC parallel port.

Dual-Interface Flash Memory Boasts 64-Mbit Performance
A 64-Mbit DataFlash memory known as the AT45DB642 includes both serial and parallel interfaces. Thanks to this dual-interface architecture, the DataFlash can reside on two distinct system buses. This in turn permits efficient interoperability between the DataFlash and multiple processors and controllers. Its architecture also features extremely small page sizes and dual internal SRAM buffers.

According to the company, it offers the same flexibility as an EEPROM while maintaining flash-memory cost advantages. It's implemented on a 25-µm process. Future models, expected to reach 128 and 256 Mbits, will shift to a 0.18-µm process. Also, it operates from a single 2.7-V power supply. Future models will work from a single 1.8-V supply. Offered in commercial and industrial temperature ranges, it comes in a small, 40-lead TSOP.

Samples are now available. It costs $28.80 in 1000-unit quantities.

Controller And Operator Interface Combined In Single Package
The SmarTouch Controller combines a C-programmable computer with a built-in graphical user interface. A single-board controller, it includes a real-time multitasking operating system, 256k flash, and 128k RAM. Also, it features a high-contrast 240-by-128 LCD display and a 5- by 4-in. touchscreen. Designers can display their own user-defined graphics on this bright white-on-blue cold-cathode fluorescent (CCFL) backlit screen.

This controller commands eight 12-bit analog input channels, eight 8-bit analog inputs, eight 8-bit digital-to-analog lines, 24 digital I/O lines, four high-current drivers, and two RS-232/485 ports. Pre-coded software for menu management, graphic routines, and I/O drivers is included as well. Additionally, it comes with an interactive debugger, multitasking executive, and other built-in programming tools.

Now available, the SmarTouch Controller costs $595 in OEM quantities.

Compiler Generates 1- To 32-kbit CAMs With 64-Bit Word Widths
The Custom-Touch NetCAM embedded content addressable memory (CAM) generates high-speed ternary CAMs. These CAMs then can be embedded into IC designs for use in routers, switches, and other network applications. This compiler also generates a number of EDA models that let designers adapt the CAMs to their design flows. Hardware-based search engines based on NetCAM technology can perform table lookups at wire speed, with up to 165 million searches a second. Generated CAMs range from 1 to 32 kbits, with 64-bit word widths.

A part-matched scheme lets the NetCAM get a fivefold speed increase over standalone CAMs. This scheme integrates or "matches" the CAM, SRAM, and additional special-purpose logic efficiently in layout for the highest performance gain. Unlike standalone SRAM-CAM subsystem configurations, this embedded CAM subsystem has no I/O pad and board wire delays. Designers can cascade embedded CAMs to build larger table sizes or widen the bandwidth of searches for increased throughput.

A single configuration lists at $200,000, while a single, node-locked compiler license for generating any configuration costs $750,000.

Boards Supply High-Resolution 16-Bit Analog Input And Output
The PCI-441C and PCI-441D single plug-in boards for the PCI bus feature 32S/16D 200-kHz 16-bit analog-to-digital channels with PGA. They come with two 16-bit digital-to-analog converters with 4- to 20-mA loops. An on-board FIFO analog-to-digital memory fully streams to disk or memory. Advanced on-board automation supports mostly unattended running. The boards also have a 32-bit digital I/O, a timer-counter, and signal conditioning.

These boards are designed for Windows 95/98/NT/2000 DLLs, LabVIEW, and ActiveX controls. Their software-programmable gain amplifier changes the standard input range of ±10 V full scale to 5-, 2-, and 1-V bipolar ranges to accommodate different transducers. Each input channel accepts additional signal conditioning for sensor and bridge inputs. On-board excitation sources directly power RTD temperature sensors and bridge circuits.

In quantities of one to four units, the PCI-441C costs $725, and the PCI-441D costs $895. Availability is from stock to two weeks ARO. Quantity discounts are available.
