PC/104 spec upgrade saves space, adds flexibility

Posted: 20 Feb 2015     Print Version  Bookmark and Share

Keywords:PC/104  OneBank  connector  specification 

This preserves the stackability and compatibility of PCI/104-Express and PCIe/104 modules along with the new OneBank modules. By removing two of the banks, 0.513in2 of PCB real estate on each side is freed up. And with speed scales up to PCIe Gen 3 on the PCIe/104 bus, developers are given plenty of bandwidth for the future even with just four x1 PCIe links.

As with all of the stackable buses adopted by the PC/104 Consortium, the PCIe/104 OneBank connector can be immediately incorporated across the Consortium's 104, EPIC, and EBX form factors. In addition, it can be used on other form factors not supported by the Consortium to provide convenient, cost effective mezzanine I/O expansion.

"The OneBank connector does a nice job of not only freeing up real estate on PCIe/104-Express peripherals... but perhaps more importantly, it can also reduce cost significantly for many peripherals for which the additional two banks for the x16 PEG have been largely superfluous and a relatively high percentage of the overall board cost. This is encouraging for our end-customers and peripheral vendors but also helps PC/104 remain cost competitive against competitive technologies." according to JC Ramirez, ADL Embedded Solutions' product manager.
