PMC Module Delivers 100 Mbits/1-Gbit Ethernet
Ethernet won't go away. It has become a key connection for networking and connectivity. From Cyclone Mi-crosystems, the PMC58 packs 100 Mbits and 1-Gbit Ethernet into a single PMC module. This module makes it easy to add Ethernet connectivity to CompactPCI or VME boards and systems. The board contains a 100/1000BaseT Ethernet port with an RJ-45 connector, and it plugs into a baseboard 64-bit/66-MHz PMC PCI bus. The PMC58 is compatible with VxWorks, and it has a driver for full TCP/IP. Pricing starts at $207 each in 1000-unit lots.

PMC Module Supports 2-Gbit/s Fibre Channel
A base for high-speed connectivity in storage systems has been established by Fibre Channel. SBS Technologies' Fibre Channel PMC modules automatically support 1- or 2-Gbit/s Fibre Channel bus rates. They handle 400 Mbytes/s of full-duplex and 200 Mbytes/s of half-duplex data rates. The FC23-PMC-1C supports a copper line via a high-speed serial data connector (HSSDC) port, and the PC23-PMC-1F supports a fiber port, multimode LC duplex fiber-optic cable. Both modules incorporate a protocol engine and handle remote DMA and SCSI. Device drivers include Solaris, Linux, and Windows NT/2000. Moreover, the modules support 64-bit/66-MHz PMC PCI. The modules cost $1285 and up.

FPGA turns a PC104 card into a universal I/O device that can be programmed via the PC104 bus. Mesa Electronics combines a 100- or 200-kgate Xilinx FPGA with 24-mA drivers and pullup resistors for 64 lines. The rest, as they say, is hardware. Such functions as a 64-channel event-capture card, a four-channel micro-controller-based servomotor controller, and an eight-channel, 32-bit timer/counter are just a few of the premade, downloadable VHDL samples provided. Multiple functions can be programmed. The 4I34 and 4I34M use two 40-pin and 50-pin connectors, respectively. The 4I34 and 4I34M are available for $123 each in quantities of 100.

25-MHz 8051 crams flash, ADC, and timers into 3- by 3-mm. The 8051 is alive and well. Here's a fast 25-MHz microcontroller packed into a 9-mm2 MLP package. It comes with a full range of peripherals. Developed by Cygnal using its proprietary 8051 CPU, the chip provides 256 bytes of RAM and 87 kbytes of flash memory. Most instructions are executed in one or two clocks.

The C8051F300 peripherals include an 8-bit ADC (eight inputs, 500-ksample/s sampling), a comparator, an on-chip debugger (four comparators) with a two-wire JTAG port, eight I/Os, UART and SMBUS serial ports, three 16-bit timer/counters, and a 16-bit PCA array.

Designed for low power, the microcontroller requires 2.7 to 3.6 V. Typical operating current is 5 mA at 25 MHz, and typical Stop Mode current is 0.1 mA. The chip contains an internal oscillator, but it can use an external oscillator, say 32 kHz, for low-power operation. Pricing starts at $3.93 apiece for quantities of 1000.
