Sensoray's Model 301-06 is a low cost, low power CPU board featuring a combination of characteristics required in most embedded applications using the PC/104+ form factor (3.8 x 3.6 inches)


The AMD Elan SC520 processor running at 133 MHz provides the performance approximately equivalent to that of a Pentium 75 processor. The board is supplied with 32 MB SDRAM and 16 MB flash disk.


The 301-06 has two serial ports (RS-232) that support communication speeds of up to 115 Kbps.

Expansion Buses

Model 301-06 supports both PC/104 and PC/104+ expansion buses. It allows up to 4 external PC/104+ devices.


The 301-06 board is integrated with a 10/100 Base-T Ethernet adapter built with a Intel GD82559ER PCI Ethernet controller. The board is equipped with an RJ45 network connector, and drivers for various operating systems are available.

Non-volatile memory

Sensoray's 301-06 is supplied with a 16 MB flash disk, which the software recognizes as a regular hard drive. A socket is provided for an optional DiskOnChip (a 3V part is required).


Only one +5V power supply is required, as the board's total power consumption is 5 watts (power dissipation is 7 watts). A power connector allows the connection of additional power supplies (-5V, +12V, -12V) to the expansion buses, if necessary.

Watchdog Timer

An I/O-mapped watchdog timer — with a time out value of 1.6 seconds — can reset the CPU or drive an open-collector output to reset external circuitry.

Bus buffers

The data, address and control bus signals are buffered to allow stacking several PC/104 boards without degrading signal quality, making it possible to add up to five PC/104 peripheral boards to one 301-06 CPU.
