This CPU board is a high performance single-board computer based on the 68030 microprocessor and the VMEbus. The CPU board also includes an enhanced Floating Point Coprocessor 68882. The board design utilizes all of the features of the powerful FORCE Gate Array FGA-002.
The CPU-30 R4 provides an A32/D32 VMEbus interface including DMA, up to 32 Mbyte shared DRAM on-board, up to 8 Mbyte System Flash Memory, an Ethernet Interface, a single-ended SCSI interface, a floppy interface, four RS-232 serial I/O channels, up to 256 Kbyte SRAM and a Real-Time Clock, both with on-board battery backup.
Besides the CPU-30 R4, there will be a CPU-30Lite R4 without a coprocessor, a SCSI, an Ethernet, and a floppy disk interface.
SEE ALSO: Please refer to Table 2, “Ordering Information,” on page 9 for more detailed information.
The shared DRAM is accessible from the 68030 CPU, the FGA-002 DMA controller, and also from other VMEbus masters.
The CPU-30 R4 has an Ethernet port and three serial ports available on the front panel permitting a console port, download and data communication channels. One further serial port, as well as the SCSI interface and the Floppy interface are available via the 3-row VMEbus P2 connector. A 20-bit parallel interface and the three serial ports on the front panel are available via the optional 5-row VMEbus P2 connector.
