Order this document by MC68EC030/D MOTOROLA SEMICONDUCTOR TECHNICAL DATA MC68EC030 Technical Summary Second-Generation 32-Bit Enhanced Embedded Controller 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 Freescale Semiconductor, Inc... Additional features of the MC68EC030 include: Complete 32-Bit Nonmultiplexed Address and Data Buses Sixteen 32-Bit General-Purpose Data and Address Registers Two 32-Bit Supervisor Stack Pointers and Eight Special-Purpose Control Registers Two Access Control Registers Allow Blocks To Be Defined for Cacheability Protection Pipelined Architecture with Increased Par...
