Chatsworth, Calif.Embedded computer supplier Aitech Defense Systems, Inc., announces two power-saving ruggedized 3U-sized cPCI (CompactPCI) SBCs (single-board computers). These SBCs operate as fast as 1.4-GHz; they also include memory and I/O options.
Available in commercial, rugged, and MIL levels, the new SBCs can be used in applications ranging from mission computers and mission control subsystems, to fire-control processing, platform stabilization, and remotely piloted vehicles, to name a few.
Aitech's C901 SBC, and the low-power C901L version, feature next-generation Freescale Semiconductor 7448 PowerPC microprocessors. These include on-chip L1 cache, and enhanced L2 cache. They also use Freescale's AltiVec Technology.
Both models can be used in cPCI subsystems as system controllers, or as CompactPCI peripheral boards. They're capable of supporting up to six additional cards on a cPCI backplane, while providing clock, arbitration, and interrupt functions.
A fully populated C901 with 512-Mbytes of DRAM operates at a typical power level of 24-W (at 1.4 GHz processor speed). The C901L version reduces that dissipation to less than 17-W (at 1-GHz). Obviously, it's for applications where dissipation is more critical than processor speed.
For additional power savings, both models offer a user-programmable so-called Dynamic Frequency Switching mechanism. Dynamic Frequency Switching reduces processor speed when processing demands are low. This permits an optimum balance between processing power and dissipation, giving the C901 SBCs a favorable power/performance ratio (MIPS/W).
Both board configurations provide up to 1-Mbyte on-chip cache, 200-MHz memory buses, and 2-Gbytes of flash. They also offer six standard variants of I/O, including multiple choices of Gbit Ethernet ports, and Fast Ethernet ports. You also get USB (Universal Serial Bus) ports, high-speed serial ports, and up to eight discrete I/O channels.
An industry-standard PMC (PCI mezzanine card) slot supports installation of additional modules and functions.
Integrated System Controller
A highly integrated Discovery III system controller functions as both a memory controller for the processor and as its bridge for the two PCI bus ports. Memory capabilities to support processor and user application needs include up to 1-Gbyte of DDR (double data rate) SDRAM with error-check-and-correction protection.
You also get 64-Mbytes of boot flash, 128-kbyte user flash, 128-kbyte of auto-store NVSRAM (non-volatile SRAM), and up to 2-Gbytes of NAND flash.
These SBCs are available in both conduction-cooled and air-cooled formats. Thermal management features include two thermal sensors positioned at temperature-critical locations. These sensors monitor and report temperature data to a user's application software. Custom heatsink modules with metal frames also enhance optimal heat dissipation.
Both the C901 and C901L are compatible as energy-saving 1:1 drop-in replacements for Aitech's earlier Model C900 SBC based on the Freescale 7447A processor. Like all boards in Aitech's C900 Series, they're available with BSPs (board support packages for WindRiver VxWorks and Green Hills Integrity realtime operating systems. They include drivers for all on-board resources.
Pricing for the C901 starts at $5300. Delivery is from stock.
