VSBC-32 COMBINED VMEBUS SYSTEM CONTROLLER AND SERIAL COMMUNICATIONS CONTROLLER BOARD
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

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
