The MC68040 integrates a floating-point coprocessor, which significantly enhances the speed and precision of floating-point operations in data processing—suitable for high-demand scenarios requiring complex industrial control algorithm calculations. The MC68LC040 does not include this coprocessor.
Memory
Offers 1MB, 4MB, or 8MB of parity-protected DRAM for storing running programs and data, ensuring data accuracy and system stability.
Features 512KB of battery-backed SRAM to retain critical data and configurations during power outages.
Interfaces
Two serial ports (EIA-232-D and EIA-232-D/EIA-530) for serial communication with devices like sensors and controllers.
Optional LAN Ethernet transceiver interface with DMA support for high-speed network communication, enabling remote monitoring and data interaction.
Six timer counters, including a watchdog timer for system timing control and fault detection. The watchdog triggers protective actions when system anomalies are detected.
Optional SCSI bus interface with DMA support for connecting external storage devices to expand system storage capacity.
Functional Features
High-Performance Data Processing and Transmission
Based on the VME bus standard, a full 32-bit workstation-class bus initially applied in m68000 computer systems and recognized by IEEE as the IEEE-1014 bus standard in 1985. The bus delivers high-bandwidth, low-latency data communication, enabling the MVME162-220 module to handle massive data and exchange information rapidly with other devices/modules. This suits applications demanding strict data processing speed and transmission efficiency, such as real-time data acquisition and processing systems in industrial automation.
