Intel Corp.'s Pentium II microprocessor is finding rising demand among board designers for embedded applications across a variety of system-bus architectures and application slices.
The processor got the nod for passive-backplane single-board computers (SBCs) from MiTAC Industrial Corp., Fremont, Calif., and I-Bus Inc., San Diego. And it's being used for VMEbus CPU boards from VMIC, Huntsville, Ala.; Concurrent Technologies Inc., Cincinnati; and DY-4 Systems Inc., Kanata, Ontario. The passive-backplane SBCs will use edge-mounted Slot 1 Pentium IIs, while the VMEbus boards will tap flush-mounted mobile modules.
MiTAC's MSC-366LX supports processor frequencies to 333 MHz, uses the Intel 440LX chipset, and withstands harsh applications, said Katy Chang, company marketer.
I-Bus' MantaRay supports Pentium IIs to 333 MHz with a 66-MHz external bus, or up to 450 MHz with a 100-MHz bus. It was designed for expandability and integration, said Curt Alexander, vice president of engineering. The board, starting at $790 with a 233-MHz Pentium II, has three 168-pin DIMM sockets and supports up to 384 Mbytes of SDRAM.
I-Bus' MantaRay ($1,775 with a 266-MHz processor) has four 168-pin DIMM sockets and supports up to 1 Gbyte of SDRAM. For $2,275, the MantaRay can have Ethernet, SCSI, and graphics on board. Its Ethernet is 10/100Base-T and its SCSI provides Ultra2 speeds.
In VMEbus, Concurrent's VP EMB/P22 has a 266-MHz Pentium II with 32 Kbytes of L1 cache, 512 Kbytes of L2 cache, and a 440BX chipset. The board, starting at $3,975, handles up to 256 Mbytes of SDRAM and 2 Mbytes of battery-backed SRAM.
VMIC's VMIVME-7696 taps a Pentium II mobile module with MMX up to 350 MHz and I/O and peripheral controllers. The board has 10/100Base-TX Ethernet, Fast Wide SCSI-2 and UltraIDE, an AGP graphics controller with 4 Mbytes of SGRAM, and a PMC expansion site. Memory includes 128 Kbytes of battery-backed SRAM, 128 Mbytes of SDRAM, and 8 to 48 Mbytes of optional boot flash. Pricing starts at $3,838 with a 233-MHz Pentium II.
DY-4's VMEbus CPU has a 266- or 300-MHz Pentium II mobile module and "all the features of a fully configured PC/AT motherboard," said Duncan Young, company marketing director. That includes up to 128 Mbytes of SDRAM; Fast SCSI-2; Ethernet; dual USB ports; four serial channels; and parallel, keyboard, and mouse ports. It will be available in the second quarter with pricing starting at $4,500.
