Woodward 5466-1035 MicroNet Plus CPU5200 Module

Description

The Woodward 5466-1035 is a MicroNet CPU5200 processor module designed to serve as a primary computational engine within high-availability MicroNet Plus and MicroNet TMR digital turbine control architectures. Powered by a Motorola PowerPC MPC5200 core processor, the 5466-1035 processes digitized telemetry data, executes governing application logic, performs fuel scheduling calculations, and outputs position demands to valve driver nodes. Onboard logic acceleration is managed via a field-programmable gate array (FPGA), which handles hardware-level VMEbus master/slave interface operations to maintain deterministic data bandwidth across the backplane motherboard. The module supports both simplex and redundant system operation. Memory capabilities include 128 MB DDR RAM and 64 MB Flash Memory, alongside an integrated real-time clock.

Installation Guidelines

• Chassis Mounting: Install into standard 14-VME format chassis slots within the MicroNet rack assembly.
• Redundancy Configuration: When operating in redundant setups, position primary and secondary units in designated parallel chassis slots to enable synchronized failover.
• Bus Overhead Management: Ensure proper backplane grounding to allow the onboard FPGA to reliably handle VMEbus data framing without logic interference.
• Power & Clock Maintenance: The internal battery automatically tops up during regular operation to maintain real-time clock tracking during power disruptions.
