The upcoming ESISA embedded bus standard, being created and maintained by cefischer solutions, bases on the well known ISA bus and defines a system architecture for 16-bit embedded applications. Designed to be stackable for eliminating the need of a backplane and thoroughly documented, it is a real alternative to PC/104. ESISA bus comes with these key features:
- Stackable modules in a compact 4 x 4'' (10.16 x 10.16 mm) form factor.
- Two DIN 41612 bus connectors for building high reliable module stacks including well-defined cabling options for stack-to-stack connections.
- Up to 6 extension modules per stack.
- Backplane and slot virtualization through Virtual Slot (VS) system including module stack auto configuration features.
- 8 MHz low frequency asynchronous bus design.
- Advanced DMA architecture supports up to 32 DMA channels.
- Interrupt architecture supports up to 64 interrupt requesters.
- ISA bus cycle compatibility allows migration of existing 8-bit and 16-bit ISA compatible add-on module I/O circuitry with minimal effort.
- Fully documented, clarified ISA bus architecture with no references to out-of-print publications.
With ESISA, the evolution of the ISA bus is still ongoing. Explore it on this site and feel free to contact us in case of any questions! Your comments are welcome!
