New module with PCI Express offers more CPU and graphic performance

19 October 2005 Computer/Embedded Technology

In introducing the smartModule SM915, Digital-Logic now offers a function- and pin-compatible upgrade of its proven SM855 computer module. The new SM915 is the smallest CPU module of its class with dimensions of 115 x 70 mm, according to the company. It offers an increased CPU performance, more graphic performance and is enhanced with PCI Express. In addition, two further S-ATA150 drives can be connected.

This tiny computer module is based on the i915GM chipset with 400/533 MHz front side bus and supports a wide range of processors from Celeron M600 up to 2,2 GHz Pentium M760 with equivalent Pentium 4 performance from 600 MHz up to 4,4 GHz.

The computer module provides all standard PC interfaces such as VGA, COM1/2, LPT1, a floppy interface, an IrDA interface, two PS/2 ports for mouse and keyboard, eight USB V2.0 ports, and has a 10/100Base-T Ethernet controller. As main memory, up to 1024 Mbyte of DDR2 RAM is available. The CPU and memory are mechanically-protected against vibrations and shocks.

Another strength of the new PC module is its high-performance graphics. The SM915 supports up to 128 Mbyte UMA video memory and DirectX 9 compatibility. The video controller has two different video outputs, VGA analog and SDVO/LVDS, to control two different monitors with the same or with different images. The standard version further includes a TV output for HDTV, NTS and PAL signals, and an AC97/HDA DTS 7.1 stereo sound system with 8-channel output and 2-channel input, a watchdog, an RTC battery support, and EEPROM support.

The SM915 is supplied by a voltage of 5 V up to 30 V, consumes between 15 W and 30 W and runs under all Windows operating systems and RTOS like VxWorks and QNX. It operates at -20 to +60°C, but at lower clock rates can also operate from -40 to +70°C.
