MC68EC030CFE25C

The MC68EC030CFE25C is a 32-bit embedded controller based on the 68030 core, implemented as a single 32-bit processor running at 25 MHz and supplied in a 132-pin CQFP (24×24) surface-mount package. It is designed for embedded control applications where integration, legacy M68000-family compatibility, and robust bus interfacing are required.

Series-level design features include on-chip instruction and data caches, a burst-mode bus interface, and dynamic bus sizing for direct interfacing with 8-, 16- and 32-bit memory devices—enabling efficient memory subsystem use and simplified system design.

Key Features

• Core & Architecture 68030 core, single 32-bit processor with object-code compatibility across the M68020/M68030/M68040 instruction sets for straightforward migration of M68000-family software.
• Performance 25 MHz operating frequency for this part; series supports 25- and 40-MHz variants. Designed to maintain performance with cost-effective memory subsystems.
• On-Chip Caches & Memory On-chip data cache (256 bytes) and instruction cache (256 bytes) reduce external memory accesses; 4‑Gbyte direct addressing range simplifies large-memory designs.
• Bus & Memory Interface Burst-mode bus interface and enhanced bus controller supporting asynchronous, synchronous and burst cycles. Dynamic bus sizing allows direct interface to 8-, 16- and 32-bit devices.
• Peripherals & Interfaces Additional SCI interface and full coprocessor support via the M68000 coprocessor interface for expanded system capabilities.
• Power & Technology 5 V I/O voltage; implemented in HCMOS technology for a balance of speed and low power (as described in the series technical data).
• Package & Thermal 132-CQFP (24×24) surface-mount package, industrial qualification with operating temperature range of -40 °C to 85 °C and RoHS compliance.

Typical Applications

• Embedded Control Systems — Use as a central controller for embedded equipment where integrated caches and robust bus control improve responsiveness and simplify memory design.
• Industrial Automation — Suited for industrial control platforms that require an industrial temperature range and durable surface-mount packaging.
• Legacy M68000 Migration — Provides object-code compatibility with M68020/M68030/M68040 series to ease migration of existing M68000-family software.
• Serial Communication Control — Built-in SCI interface supports serial communications tasks within embedded systems and control applications.

Unique Advantages

• Highly Integrated Controller: On-chip instruction and data caches, access control and an improved bus controller reduce external component count and simplify system design.
• Flexible Memory Interfacing: Dynamic bus sizing and burst-mode transfers enable direct connection to a mix of 8-, 16- and 32-bit devices and efficient DRAM access.
• Legacy Compatibility: Object-code compatibility with earlier M68000-family processors eases software migration and protects prior development investments.
• Industrial-Grade Operation: Industrial qualification and an operating range of -40 °C to 85 °C support deployment in temperature-demanding environments.
• Surface-Mount Packaging: 132‑CQFP (24×24) package provides a compact surface-mount option for high-density board designs.
• Standards-Aligned Supply: 5 V I/O and RoHS compliance align the device with common industrial supply rails and environmental requirements.
