What is EPIC?

22 September 2004 Computer/Embedded Technology

The 'Embedded Platform for Industrial Computing' (EPIC) is a new physical platform for embedded single board computers (SBCs). Five leading SBC manufacturers have defined and created this new standard in response to the need seen in the market for an open-architecture, embedded platform that is larger than a PC/104 module yet smaller than an EBX board.

Size matters

The EPIC form factor is larger than a 90 x 96 mm PC/104 board yet smaller than a 146 x 203 mm EBX board. The midpoint between EBX and PC/104 is 191,2 cm². EPIC is 190 cm².

The 115 mm x 165 mm size is optimal for including full PC/104-Plus compliant expansion cards (ISA and PCI buses) and a rich set of I/O implemented as either pin-headers or moulded PC-style connectors. Other form factors proposed during the last several years tried to fill the void between PC/104 and EBX size boards. However, these alternatives are plagued with inconsistent connector locations and expansion schemes, fail to address the needs of I/O-intensive applications, and have not evolved into a widely supported published specification.

'Bridge to the Future'

The creators of EPIC have made provisions for long-term technology support. Unlike the other mid-sized boards, ample board space has been reserved to support the broad base of PC/104 and PC/104-Plus I/O modules as well as emerging high-speed bus technologies such as PCI Express without sacrificing I/O capacity. Due to this unique architecture, compliant implementations can smoothly migrate legacy ISA-based systems to the fast serial interfaces of the future.

Specification

EPIC has a published, governing specification written by its developers. It may be downloaded from www.epic-sbc.org
