The Enhanced 486 Security System-on-Module SECSOM-486 is a highly integrated multi part module based on the ZFx86 SoC. An enhanced 80486 class CPU running at 66 MHz is combined with 128 MBytes SDRAM, 4 MBytes of F-RAM to store the BIOS, OS and application data, a USB 1.1 host/ device controller and a Hifn 7954 processor as security and compression companion.

The SECSOM-486 builds on a 21x21 PGA connector which allows high reliable module to board connections and an easy escape routing from the device. Since the module is protected by an enclosure the SECSOM-486 is perfectly suited for rugged environments. The SECSOM-486 has a maximum power consumption of about 8 W and can be used in fanless applications.

Exporting a 32-bit PCI expansion bus running at 33 MHz and a 16-bit ISA expansion bus, the SECSOM-486 can be connected to lots of I/O and memory devices without additional glue logic. A USB host/ device controller offers USB 1.1 up and downlink ports thus, allowing the SECSOM-486 to act as both, USB host and USB device simultanously. Two ATA-4 IDE channels, one IEEE 1284 port and one EIA/TIA-232 interface are also available. Besides, the SoM is accessible for maintenance tasks through a dedicated EIA/TIA-232 interface connectable to any host device that has a serial port (virtually any PC).

The SECSOM-486 comes with our Protected Mode RTOS µPMOS preloaded which makes the module and all its interfaces fully operational within a few seconds after POST and directly programmable through the maintenance port without any additional development tools.
