Emerson / Motorola / Force Computers SYS68K CPU-44C/16 Single Board Computer

The Emerson/Motorola/Force Computers SYS68K CPU-44C/16 is a VMEbus single-slot single board computer designed for embedded systems and industrial control applications. Built around the Motorola XC68040 microprocessor, this board delivers high-performance computation with integrated memory, network connectivity, and multiple I/O interfaces for demanding real-time environments.

## Technical Specifications

**Processor**

• 4 KB on-chip program cache and 4 KB on-chip data cache
• Integrated floating-point unit rated at 5.6 MFLOPS
• Peak performance: 35 MIPS
• Full backward compatibility with 68000-family software

**Memory**
• 16 MB DRAM configured in two interleaved banks
• Burst read rate: 70 MB/s
• Buffered write rate: 79 MB/s

**Interfaces & I/O**
• VMEbus/IEEE 1014 controller
• Ethernet network interface
• Six 16-bit timer/counter channels
• IOC-2 gate array
• FLXi local expansion interface for modular I/O subsystems

**Firmware**
• VMEPROM real-time multitasking monitor/debugger in Flash EPROM

## Key Features

The CPU-44C/16 combines high-bandwidth memory transfers with flexible I/O expansion. The 68040’s integrated cache and FPU eliminate external coprocessor dependencies. Dual-bank interleaved DRAM architecture minimizes memory bottlenecks in data-intensive applications. The FLXi expansion interface enables custom I/O subsystems without redesigning the core processor board.

## Typical Applications

Industrial process control, embedded data acquisition, real-time signal processing, and VMEbus-based instrumentation systems benefit from this board’s compute density and modular I/O capabilities.

## Compatibility & Integration

The SYS68K CPU-44C/16 integrates directly into VMEbus backplanes and supports 68000-family software, simplifying migration from earlier Motorola processor architectures. The onboard Ethernet interface provides network integration without additional controller boards.
