Description

The MVME147 series is a family of VMEbus single-board computers. The on-board resources and peripheral controllers eliminate the need for additional modules in the VMEbus backplane thus reducing costs and freeing up valuable bus slots for additional functions. The MVME147 series features an MC68030 enhanced 32-bit microprocessor. The MC68030 was the first general-purpose microprocessor with on-chip cache memory for both instructions and data, which increases the processor’s efficiency by 20 to 40 percent. The MC68030 features a complete memory management unit (MMU) that provides the software protection and virtual memory functions critical to many applications.
The MVME147 CPU module provides:

68030 processor running at either 16MHz (SRF model), 20MHz, 25MHz (Sx-1 models) or 32MHz (Sx-2 models), with on-chip Paged Memory Management Unit • 4, 8 (SA-x models), 16 (SB-x models), or 32M (SC-x models) of on-board DRAM
Four RS-232C Serial Ports
Centronics Parallel Printer Port
On-board SCSI Interface
Ethernet Transceiver Interface (except for -RF/-SRF models)
Time-of-day clock/calendar with battery backup
2Kx8 Battery backed CMOS RAM (NVRAM) The OS-9 area of NVRAM is the first 256 bytes of the user area beginning at address FFFE0000.
Four JEDEC EPROM sockets organized as two banks of 16-bit wide (high and low byte) memory:
MVME147:
Primary ROM Bank: FF800000 High Byte U1 / Low Byte U2
Secondary ROM Bank: FFA00000 High Byte U16 / Low Byte U18
• MVME147S:
Primary ROM Bank: FF800000
High Byte U22 / Low Byte U30
Secondary ROM Bank: FFA00000
High Byte U1 / Low Byte U15
There are two possible ROM configurations for the MVME147. As the system installer, you must choose which ROM configuration to adopt, depending on your system application. • The first retains the 147Bug ROMs in the primary bank (for ease of hardware diagnostic testing) and adds the OS-9 RomBug EPROMs in the secondary bank. In this configuration, 147Bug gets control on a reset and “boots” RomBug in the secondary bank.
