MC68EC030集成电路（IC）的微处理器规格书PDF中文资料

The MC68EC030 is a 32-bit embedded controller that streamlines the functionality of an MC68030 for the requirements of embedded control applications. The MC68EC030 is optimized to maintain

performance while using cost-effective memory subsystems. The rich instruction set and addressing mode capabilities of the MC68020, MC68030, and MC68040 have been maintained, allowing a clear migration path for M68000 systems. The main features of the MC68EC030 are as follows:

• Object-Code Compatible with the MC68020, MC68030, and Earlier M68000 Microprocessors

• Burst-Mode Bus Interface for Efficient DRAM Access

• On-Chip Data Cache (256 Bytes) and On-Chip Instruction Cache (256 Byte)

• Dynamic Bus Sizing for Direct Interface to 8-, 16-, and 32-Bit Devices

• 25- and 40-MHz Operating Frequency (up to 9.2 MIPS)

• Advanced Plastic Pin Grid Array Packaging for Through-Hole Applications
