The MC68EN360 processor is also available with two different clock rates:
• 25MHz
• 33MHz (this variant is again supplied with either 256kB or 1MB SRAM).
The below described frontend connectivity and interface expandibility are common to all
board variants.
1.2.3 Board Connectivity and Interface Expandibility
The VSBC-32(E) mainboard is provided with the following standard connectors:
• Non-optoisolated RS232 serial interface (two RJ45 connectors, on frontpanel)
• One set of piggyback interface connectors for serial interface (SI) piggybacks
(three 7-pin row male connectors)
• One set of memory piggyback interface connectors
(two 50-pin row female connectors)
• Two sets of (flash) EPROM DIP sockets
(two 32-pin row female sockets)
• Background debug mode (BDM) interface (one 12-pin row male connector)
• VMEbus backplane interface
(one 96-pin DIN 41612, style C male connector)
• Enhanced CXC mezzanine interface
(one 96-pin DIN 41612, style C male connector)
In addition, the mainboard external interfacing is usually integrated by one of the follow-
ing piggyback-mounted frontpanel interface options (serial interface piggybacks). The
kinds of piggyback that can be used depend on the mainboard variant.
Applications requiring further communication interfaces may be upgraded by means of
an external CXM-SIO3 serial interface module which provides the following interface
extension possibilities:
• RS232 serial interface connectors (non-optoisolated)
• Serial interface piggyback ports
• Serial communications piggyback port
