function
Super powerful computing performance
25MHz MC68020+high-speed MC68882 floating-point, with processing capabilities far exceeding the 12.5/16.67/20MHz versions of the same series, suitable for complex algorithms, high-speed data acquisition, and real-time simulation.
Extra large local memory
4MB 32-bit DRAM, eliminating the need for frequent access to the VME bus, significantly improves multitasking and big data throughput performance, and is compatible with large RTOS such as VxWorks and pSOS.
Fully functional VME controller
Supports A32/D32 large address space and can be used as a VME chassis system controller to manage multi board collaboration and build large-scale distributed control systems.
Industrial grade stability
Hardware watchdog, battery RTC/NVRAM, redundant serial port, wide temperature design, to meet the long-term operation of harsh working conditions in military, aerospace, power and other industries.
