Emerson / Motorola / Force Computers SYS68K CPU-40B/16-01 Single Board Computer

The Emerson / Motorola / Force Computers SYS68K CPU-40B/16-01 is a VMEbus-based single-board computer built around the Motorola 68040 microprocessor operating at 25 MHz. It integrates 16 Mbyte shared DRAM with burst read/write capability, 128 Kbyte battery-backed SRAM, and 128 Kbyte Flash EPROM with on-board programming. A high-speed 32-bit DMA controller (FGA-002) manages data transfers across shared memory, VMEbus, and I/O subsystems.

## Technical Specifications

• Processor: Motorola 68040 microprocessor
• Clock Speed: 25 MHz
• Shared DRAM: 16 Mbyte with Burst Read/Write and Parity Generation and Checking (DRM-01/16 module)
• SRAM: 128 Kbyte on-board with battery backup
• Flash EPROM: 128 Kbyte with on-board programming support
• DMA Controller: High-speed 32-bit (FGA-002) supporting VMEbus and I/O subsystem transfers
• System EPROM: Two 40-pin sockets with 32-bit data path; one Boot EPROM for initialization and FGA-002 configuration
• Real-Time Clock: On-board with battery backup

## Key Features

• Four front-panel serial I/O interfaces configurable as RS232, RS422, or RS485
• 8-bit Parallel Interface with 4-bit handshake
• Modular I/O expansion via FLXi (FORCE Local eXpansion interface) supporting 32-bit data paths
• EAGLE-01C module compatibility for expanded I/O capabilities
• VMEPROM firmware (Real Time Kernel) included

## Typical Applications

Industrial control systems, real-time data acquisition, embedded VMEbus applications, and systems requiring flexible serial and parallel I/O with deterministic timing.

## Compatibility & Integration

Designed for VMEbus architecture integration. Supports EAGLE modular I/O subsystems through the FLXi expansion interface, enabling scalable system configurations without redesign.
