STPC-based SBCs boast reduced cost, power

Sep 23, 2004 — by LinuxDevices Staff — from the LinuxDevices Archive

Kontron has introduced a pair of new products based on STMicroelectronics x86-compatible system-on-chip (SoC) processors. Built in two of Kontron's standard form-factors, the ETX-e.lite and DIMM-PC/lite are both based on ST's 100MHz 486-class STPC Elite processor (with integrated floating point unit). The SBCs support Linux.

Kontron expects the new STPC-based DIMM-PC and ETX form-factor SBCs to be used in “cost-sensitive mass market applications” in building security, numerical control, SOHO (small office, home office) equipment, GPS/GPRS devices, set-top boxes, and test/measurement equipment, it says.


Kontron is offering the STPC-based DIMM-PC/lite SBC in three flavors (lite-I, lite-IE, lite-IU), each based on a 100MHz STPC Elite processor and equipped with 32MB of SDRAM along with 32MB of IDE-compatible flash storage memory. Kontron says the “ultra-low-power” design of the DIMM-PC/lite makes it suitable for fanless systems. All three versions include PC-compatible interfaces for serial (2), parallel, keyboard, and floppy. The “lite-IU” adds a USB 1.1 port, while the “lite-IE” substitutes a 10-Mbit Ethernet network interface for the USB port on the “lite-IU”. Board dimensions are 2.7 x 1.6 inches (68 x 40 mm).


The ETX-e.lite is also based on a 100MHz STPC Elite processor, and comes with 32-128MB of soldered-on SDRAM. The SBC includes a CompactFlash socket, along with the option of a soldered-on “vibration-proof” flash disk of up to 128MB capacity. Like its smaller DIMM-PC cousin, the ETX-e.lite is suitable for fanless operation, Kontron says. Despite its compact size (4.6 x 3.7 in.; 95 x 117 mm), the ETX-e.lite boasts a standard array of PC interfaces, including 2 EIDE ports, 2 serial ports, 1 parallel port, 2 USB 1.1 ports, and a 10/100-Mbit Ethernet port. Up to four audio channels can be added as options. Typical power consumption is 4W at 5VDC.
