Features of the MC68VZ328
The features of the DragonBall VZ include the following:
•
Static FLX68000 CPU—identical to the MC68EC000 microprocessor
— Full compatibility with MC68000 and MC68EC000
— 32-bit internal address bus
— Static design that allows processor clock to be stopped to provide power savings
— 5.4 MIPS performance at 33 MHz processor clock
— External M68000 bus interface with selectable bus sizing for 8-bit and 16-bit data ports
•
System integration module (SIM) that incorporates many functions typically related to external
array logic, reducing parts counts in design, with functions that include the following:
array logic, reducing parts counts in design, with functions that include the following:
— System configuration and programmable address mapping
— Glueless interface to SRAM, DRAM, SDRAM, EPROM, and flash memory
— Eight programmable chip-selects with wait-state generation logic
— Four programmable interrupt I/Os, with keyboard interrupt capability
