Introduction
The BVME370 and BVME380 form a family of 32 bit processors based on the 68EC030/68030 CPUs. They are general purpose processor modules with full master/slave VMEbus interface offering excellent price and performance for many applications.
The BVME380 uses the full 68030 CPU which includes a memory management unit providing hardware memory protection, whilst the BVME370 uses the 68EC030 and is particularly suitable for cost effective embedded applications. Each is available with a variety of processor clock speeds up to 40MHz, and all units can be fitted with the optional 68882 floating point co-processor.
The 4MBytes of high speed DRAM are dual ported onto the VMEbus and the slave interface also supports "mailbox" interrupts, making it particularly suitable for multi-processor applications.
