The CPU-5CE/32 is a SPARC-based VME single-board computer engineered for embedded and industrial applications requiring high integration and expandability. Built around a microSPARC-II processor running at 85 MHz, this 6U VMEbus card consolidates CPU, memory, and I/O onto a single IEEE 1014-compliant module. The architecture supports two SBus expansion slots for additional memory, processing, and I/O capability.

## Key Features
The integration of standard interfaces—Ethernet, Fast SCSI, dual serial ports, and parallel I/O—enables direct system connectivity without requiring external interface adapters. Two SBus slots provide the flexibility to augment onboard resources or add specialized processing capability. OpenBoot firmware simplifies device configuration, VMEbus interface setup, and system diagnostics during development and deployment phases.
## Typical Applications
This board targets demanding embedded control systems, real-time data acquisition, industrial instrumentation, and telecommunications equipment where SPARC processing and VMEbus integration are required.
## Compatibility & Integration
The CPU-5CE/32 operates with Solaris and real-time operating systems including VxWorks, enabling deployment in both general-purpose UNIX and deterministic real-time environments. Full compliance with IEEE 1014 VMEbus standards ensures integration into existing VME backplane systems. SBus peripheral compatibility permits modular system expansion without redesign.
