1.2 Board Overview
1.2.1 Board-Specific Information
The VSBC-32(E) is a 3U (Enhanced) CXC combined system and communications con-
troller board that can operate in either a VMEbus or a mixed VMEbus+CXC environ-
ment. The board is based on the Motorola Quad Integrated Communications Controller
“QUICC” MC68(EN)360. Therefore, it is particularly suitable for system control functions
within applications with communications requirements. Depending on the controller chip
used, there are two board variants with different CPU frequencies. The board’s external
interfacing consists of a twin RS232 interface connector, which can be extended by
means of a variety of serial interface piggybacks and/or external serial interface mod-
ules. Other piggybacks provide DRAM/flash memory.
Some of the outstanding features of the product described in this manual are:
• VMEbus system and communications controller board
• Both VMEbus and eCXC connectivity
• Master/slave system controller functionality
• 32-bit Motorola MC68(EN)360 integrated CPU and communications controller
• 25Hz or 33Hz CPU frequency
• CPU on-chip background debugging
• 1, 4, 16, 32 or 64 MB DRAM
• 0, 0.5, 1, 2 or 4 MB flash memory
• 256kB or 1 MB SRAM
• 2kbit serial EEPROM
• 256kB or 1MB DIP (flash) EPROM
• Real-time clock (backed-up)
• Six different communication standards possible:
•
Serial I/O (RS232, RS485; RS422 on request)
• Ethernet (10Base2, 10Base5 or 10BaseT Ethernet)
• Up to six frontpanel serial interface connectors
• Compatibility with external serial interface module CXM-SIO3
• Reset and Abort control (frontpanel buttons)
• Halt, watchdog and general-purpose status indicators (frontpanel LED’s)
• OS-9 and VxWorks ® drivers
1.2.2 Board Variants
Two basic variants of the VSBC-32(E) with different processors are available. Depend-
ing on the controller chip used and the SRAM size, there are four variants of the VSBC-
32(E) system and serial communications controller board. The distinctive features of the
variants are listed in the following
• Ethernet capability
• CPU frequency
• SRAM size
The following basic board variants are available:
• VSBC-32: MC68360 processor, no Ethernet control capability.
• VSBC-32E:MC68EN360 processor, Ethernet control capability.
