Total EBR 1553 SPI – Complete SPI to EBR 1553 Interface Solution

The Total EBR 1553 SPI from Sital Technology is the first fully integrated EBR-1553 component. It simplifies system design by merging digital, protocol, and physical layers into one compact device.

Ideal for avionics, defense, and automotive bus systems. The Total-EBR1553SPI provides a true drop-in solution for engineers needing deterministic performance. Provides low EMI, and software compatibility—all in a miniature, U.S.-fabricated component.

Key Specs:

Host interface: Single/Dual SPI up to 50 MHz
Modes: BC / RT / MT / RT-Monitor
Core clock: 80 MHz internal
Cable length: up to 50 m RS-485 (per your validation)
I/O voltage: 1.8 V / 2.5 V / 3.3 V
Software: Windows, PetaLinux, VxWorks, bare-metal

It is built upon Sital’s proven MIL-STD-1553B engine. Used across avionics and military platforms since 2005. Ensuring long-term reliability, software compatibility, and immunity to obsolescence.

EBR-1553, designed to deliver MIL-STD-1553-like deterministic behavior at higher data rates (10 Mb/s), has historically lacked a unified standard. This led to multiple dialects and interoperability issues. The Total-EBR-1553 SPI resolves these challenges by supporting all common EBR dialects, automatic SPI width detection, and seamless integration with DDC® Enhanced Mini-ACE® (EMA®) software environments.

Total-EBR 1553 SPI Component

Safe and Secure DataBus Solutions

Sital’s cutting-edge, innovative “SnS” Technology is designed for IP Core’s physical layer. Our solutions offer unprecedented cyber security and DataBus fault finder capabilities.

We supply our products with DO-254 and DO-178 certifiability, including DAL A. Our partners: Logicircuit and ConsuNova provide the DO-254 and DO-178 artifacts. Through enhanced physical layer monitoring, the patented “SnS” analyzes all DataBus messages and provides 2 unique capabilities.

Cyber Security

Validate each Bus message and prevent any malicious Bus messages from executing their attack! This includes BC firewall and an option to add “SnS” for cyber security IDS/IPS to new and existing MIL-STD-1553 designs.

Wire Fault Detection

Detect and pinpoint intermittent and continuous electrical faults such as open and short circuits! “SnS” also analyzes the overall health management analysis of the DataBus.
