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
