Board Appointments

CompactPCI dual PMC host board makes the most of the 1.8GHz Intel Pentium M processor 745.

Concurrent Technologies has added the PP 312/01x to its range of CompactPCI boards. The board has the low power 1.8GHz Intel Pentium M processor 745 (formerly codenamed Dothan) that increases the L2 cache size from 1 to 2 Mbytes and also provides an improved performance to power dissipation ratio. It supports up to 2Gbytes DDR ECC SDRAM. In addition to two PMC sites with front and rear I/O, the PP 312/01x supports dual Gigabit Ethernet, PICMG 2.16 (packet switching backplane), PICMG 2.9 (IPMI) and PICMG 2.1 (hot swap). It can operate as a system controller board, a peripheral board or as a satellite board (blade).

As an intelligent PMC carrier with dual 64bit 66MHz PMC sites, the PP 312/01x deals with intensive I/O or data applications. Each site supports 3.3V or 5V PCI signalling and is available for user modules, standard PMC or PrPMC modules. As well as front I/O, the PMC I/O connector signals from both PMC sites are routed to the rear connectors (J4 is not used). Plus, for faster CompactPCI control/data plane throughput the PP 312/01x can auto-configure, on insertion/power-up, in a system operating at 66MHz backplane PCI signalling speeds.

To cater for embedded applications there is 32Mbytes of application flash memory and 512Kbytes of battery backed SRAM.

When applications require it, there is an EIDE interface (up to Ultra-DMA100), with installed EIDE options for an onboard EIDE 2.5in disk drive or CompactFlash/IBM (Hitachi) Microdrive carrier, both within a single slot. For applications requiring rear I/O connections a transition module is available.

VME boards
As well as unveiling the PP 312/01x, Concurrent has also launched its latest VME board, the VP 307/01x, which also features the 1.8GHz Intel Pentium M processor 745. This single slot SBC supports up to 1.5Gbytes DDR ECC SDRAM.

With an onboard PMC site and expansion for two more PMC sites (all with rear I/O), the VP 307/01x rear I/O functions include dual Gigabit Ethernet, optional VITA 31.1, analog/digital graphics, keyboard, mouse, RS232/422/485, USB, floppy and EIDE interfaces.

The front panel supports the PMC and analogue/ digital graphics, keyboard, mouse interfaces including additional front panel interfaces for USB, RS232/ 422/485 and Fast Ethernet. The VP 307/01x is a form, fit and function addition to the VP 305/01x family.

VITA 31.1 (Gigabit Ethernet on VME64 Backplanes) provides the system designer with the features of an embedded system area network using Gigabit Ethernet, without the need for external cables or external Ethernet switches. The VITA 31.1 standard is the VME equivalent to the CompactPCI PICMG 2.16 standard.

One aspect of the VP 307/01x design provides soldered on 512 Mbytes of DDR ECC SDRAM that can easily be upgraded to 1.5Gbytes via the onboard memory socket. To cater for embedded applications, there is 32Mbytes of application flash memory. For a wider range of applications there is an EIDE P2 interface (up to Ultra-DMA100).

Other onboard features available are GPIO bits, speaker interface, PC real-time clock, watchdog timer, long duration timer and LAN boot firmware. A transition module is supplied for applications requiring rear I/O connections.
