Intel® Atom® Processor E3845 ETX CPU Module

  • Onboard Intel® Atom® Processor E3845, 1.91GHz
  • 1x DDR3L SO-DIMM, Max. 8GB
  • Supports CRT, LVDS and 1x DDI
  • 1x 10/100Mbps LAN
  • Watchdog timer, LPC to ISA
  • 1x SATA II, 2x IDE, 4x USB 2.0, 2x COM
  • Wide-range operating temperature from -20°C to 70°C
  • Wide Temperature

The ET839 ETX module supports industrial wide temperature (-20°C ~70°C) and low heat dissipation efficiency, making it ideal for use in fanless applications in harsh environments. The platform is powered by a 1.91GHz quad-core Intel® Atom® Processor E3845 SoC that features scalable performance that allows simple replacement or upgrade of current Bay Trail-I ETX solutions without changing the baseboard, regardless of the chassis and thermal designs.

ET839 ETX module

The ET839 ETX module also gives customers with flexibility to design different carrier boards with different I/O interface, connectors and functionality specific to their needs and reduce time-to-market.

The new ET839 (95 x 114mm) supports up to 8GB of DDR3L SO-DIMM system memory. Integrated graphics enable dual independent displays via 24-bit dual channel LVDS and CRT graphics outputs with resolutions up to 1600 x 1200 and 2048 x 1536 respectively. Other interfaces and expansion provided include 4x USB, SATA II, 2x IDE, 2x COM, audio, LAN, LPT, PS/2 keyboard/mouse, as well as PCI and ISA bus.
