On-Board Computer

ODALISS OBC is designed to provide high computational performance with a flexible power consumption in data-intensive space systems such as nanosatellites, microsatellites, or specialized payloads.

The ODALISS OBC is based on a dual-core processing CPU that includes a rich ecosystem of peripherals to control the most demanding avionics subsystems and payloads.

Main Features:

  • Powerful dual-core architecture: Cortex®-M7 for high-performance processing unit, and Cortex®-M4 for mission-critical systems control.
  • BC includes a 10/100Mbps Ethernet switch to seamlessly implement standard TCP/IP backplane LAN with up to 5 nodes.
  • Safety-centric architecture including RTC, voltage monitoring and watchdog.
  • Flexible logic interface (UART, RS-485, I2C, etc.).
Specifications
  • CPU
    • Dual 32-bit STM32 processor unit, ARM® Cortex®-M7 + Cortex®-M4, at 480MHz, with double-precision FPU, data and instruction cache and DSP instructions.
    • Redundant (independent and window) watchdog for each core.
    • Low-voltage monitor.
  • Memory
    • Up-to 256GB eMMC NAND flash for long-term data storage. 64 MB SDRAM provides fast access to data.
    • 256KB FRAM for critical information.
    • 128MB NOR flash.
  • Connectors
    • Two 80-pins high-speed interface backplane connectors.
    • Two 5-pin for external programming and communication.
    • Pogo-style for program and debug without mechanical stress.
