Advantech announces a new series of COM modules that support the new COM 2.0 specification. The newly-introduced COM Express™ COM.0 Revision 2.0 by the PCI Industrial Computer Manufacturers Group (PICMG®) takes Computer-on-Modules into a new era with smaller footprints and expanded pin-outs.
COM.0 R.2.0 Specification Features
 |
Up to three Digital Display Interface (DDI): HDMI, DisplayPort and SDVO |
|
Increased PCI Express lanes, with additional high-speed I/O - USB 3.0 and SATA 3 |
|
Expanded functions for type 6 and type 10 pin-outs |
|

The Computer on Module specification was adopted by PICMG in 2005. In Rev. 1.0, there were a total of 5 pin-outs (Type-1 to Type-5 pin out). As new technology evolved, the market demand grew for graphic performance, more bandwidth and faster I/O interface. Recently the PICMG group officially released revision 2.0 of the COM Express standard by adding two new pin-out types Type-6 and Type-10. Type-6 is based on Type-2 which is 2 connectors. Type-10 is based on Type-1 which is one connector. Revision 2.0 has adopted new technology such as USB 3.0, digital display interface (DDI) and more PCI Express lanes, and removed old interface such as IDE and PCI.
NOTE! Rev. 1.0 and Rev. 2.0 use the same connectors and form factors, however the pin-out definitions are different and difficult to distinguish from their appearance alone. Most customers are still using Rev. 1.0 carrier boards and therefore must pay close attention when adopting Rev.2.0 COM Modules for carrier boards designed for Rev. 1.0. |

| 1. If Type 2 Rev. 2.0 COM plugs into a Type 2 Rev. 1.0 carrier boards: They should be fine except the TV-out function will not work and the SPI interface doesn’t exist on Rev. 1.0 carrier boards. |
|
| 2a. If Type 6 Rev. 2.0 COM plugs into Type 2 Rev. 1.0 carrier boards: The COM might be damaged by VCC_12V (Row A pin-97 to 99 pin-101 to 103, and Row B pin-101 to 103). |
|
| 2b. Advantech SOM-5890 is based on Rev. 2.0 Type-6 and has a protection circuit to prevent damage from VCC_12V. When plugged into Rev. 1.0 carrier boards: they should be fine, however several functions on the carrier board will not work, such as PCI and IDE interfaces designed for Rev. 1.0. |

|
| 2a. If Type 10 Rev. 2.0 COM plugs into Type 1 Rev. 1.0 carrier boards: The COM might be damaged by VCC_12V. If customers insist on it, the carrier board or CPU module must have a hardware modification for those VCC_12V pins. |
