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

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 Parallelism Allows:

– Internal Caches Accesses in Parallel with Bus Transfers

– Overlapped Instruction Execution

• Enhanced Bus Controller Supports Asynchronous Bus Cycles (three clocks minimum),

Synchronous Bus Cycle (two clocks minimum), and Burst Data Transfers (one clock)

• Complete Support for Coprocessors with the M68000 Coprocessor Interface

• Internal Status Indication for Hardware Emulation Support

• 4-Gbyte Direct Addressing Range

• Implemented in Motorola's HCMOS Technology That Allows CMOS and HMOS (High-Density

NMOS) Gates To Be Combined for Maximum Speed, Low Power, and Small Die Size
