Motorola MVME-2400

Product Overview

The MVME-2400 is a high-performance VME single-board computer (SBC) from GE (formerly Motorola Computer Group), designed for embedded computing in industrial automation, military/aerospace, telecommunications, and medical systems. It features the low-power, high-performance MPC750 PowerPC microprocessor (233/350/450 MHz) with 32KB/32KB L1 cache and 1MB L2 cache, delivering robust processing for real-time control and data acquisition. The board integrates 32MB–512MB ECC SDRAM (100 MHz PC100), 8MB Flash, and 1MB PROM for reliable operation in harsh environments, and includes dual PMC (PCI Mezzanine Card) slots for flexible I/O expansion—supporting up to six PMCs with optional PMCspan modules. It provides 10/100Base-T Ethernet, RS232/RS485 serial ports, and VME64 interface (64-bit/66MHz, 40MB/s max) for seamless integration with legacy and modern systems.

Function Features

  • High-Performance Processing: MPC750 PowerPC (233/350/450 MHz) with 32KB L1 and 1MB L2 cache delivers deterministic performance for real-time control and data acquisition.
  • ECC Memory Protection: 32MB–512MB ECC SDRAM detects and corrects single-bit errors, preventing data corruption in harsh environments.
  • Dual PMC Expansion: Two 64-bit PMC slots support I/O customization (Ethernet, serial, analog I/O, Fibre Channel) with optional PMCspan for up to six PMCs.
  • VME64 Backplane: 64-bit/66MHz VME interface ensures compatibility with legacy VME systems and high-speed data transfer (40MB/s max).
  • Real-Time OS Support: Compatible with VxWorks, LynxOS, QNX, and Linux for deterministic task scheduling and low-latency I/O.
  • Integrated I/O: 10/100Base-T Ethernet, RS232/RS485 serial, parallel, and USB 1.1 ports enable direct connectivity to sensors, actuators, and networks.
  • PPCBug Debugging: On-board firmware with serial debug port allows low-level diagnostics and system bring-up.
  • Wide Temperature Operation: -40°C to +85°C range ensures reliable performance in industrial, military, and aerospace environments.
  • Long-Term Availability: GE’s legacy support and VME ecosystem compatibility guarantee 10+ year product lifecycles for embedded systems.
  • Modular Design: 6U VME form factor fits standard racks; hot-swappable PMC modules enable field upgrades without system shutdown.

Application Scenarios

  • Industrial Automation: Core controller for PLCs, DCS, and robotics; processes 100+ sensor inputs in real time (e.g., automotive assembly lines, oil & gas refineries).
  • Military & Aerospace: Embedded computing for avionics, radar systems, and unmanned vehicles; meets MIL-STD-810G for shock, vibration, and temperature extremes.
  • Telecommunications: Base station controllers and network routers; handles 10/100Base-T traffic and protocol conversion (SS7, ATM) with deterministic latency.
  • Medical Equipment: Image processing for CT/MRI scanners and patient monitoring systems; ECC memory ensures data integrity for diagnostic accuracy.
  • Energy & Utilities: Substation automation and grid control; processes IEC 61850 GOOSE/MMS messages and integrates with SCADA systems via Modbus TCP.
  • Transportation: Train control systems (TCMS) and traffic management; VME backplane supports redundant communication for safety-critical operations.
  • Aerospace: Satellite on-board computers and launch vehicle telemetry; low-power MPC750 processor optimizes battery life for space missions.
  • Legacy System Retrofit: Direct replacement for aging VME SBCs; preserves existing backplane infrastructure while upgrading processing power and I/O capabilities.
