MISSISSAUGA, Ont. The Model 5811 single-board computer from Toronto Microelectronics Inc. packs the guts of an embedded system into the 8 x 5.75-inch EBX form factor, and it's the first, according to the company, that accommodates up to 512 Mbytes of ECC SDRAM.
"Systems with more than 32 Mbytes are known to have soft memory failures," said marketer Michelle-Anne Breau. "ECC can reduce these system failures, hence increasing the success rate in mission-critical applications."
The SBC supports either an Intel Pentium MMX or an AMD K6-2/3D microprocessor operating at 166 to 450 MHz and featuring a 100-MHz system bus and a PC/104-Plus expansion site.
The 5811 contains a l0/l00 Base T Ethernet controller and an Ultra Fast/Wide SCSI-3 controller: specifically, Intel's 82558 and the LSI Logic Symbios 53C875. An on-board LCD controller is also provided, as is a touch-screen interface and four serial ports. The LCD interface uses the low-voltage differential signaling (LVDS) standard, capable of driving full-color, high-resolution LCDs at distances of up to 20 feet.
"High-resolution flat-panel cables are known as a primary reason for failing to meet FCC tests," said Breau. To cope with this problem, "the on-board LVDS helps to significantly reduce electromagnetic interference."
The board has a 144-Mbyte flash disk and, with two 168-pin DIMM sockets, it can take up to 512 Mbytes of ECC SDRAM. With a 350-MHz K6-2/3D, it is priced at $775 each in quantities of 100 and is available from stock.
