MC68EC030FE25CB1

The MC68EC030FE25CB1 is a 32-bit embedded microprocessor based on the 68030 core, supplied in a 132-pin CQFP (24×24) surface-mount package. Designed for embedded control applications, it integrates the MC68030 integer unit with on-chip caches and an enhanced bus controller to streamline system-level design.

This device targets designs that require a single 32-bit core running at 25 MHz with a nonmultiplexed address/data bus and support for flexible memory interfaces. Key value propositions include integrated cache, dynamic bus sizing and a burst-mode bus interface that simplify interfacing to diverse memory subsystems.

Key Features

• Core — 68030 single 32-bit core running at 25 MHz, maintaining the M68000-family instruction set and addressing capabilities.
• On-Chip Caches — 256-byte instruction cache and 256-byte data cache to reduce external memory accesses and improve throughput for embedded tasks.
• Burst-Mode Bus Interface — Supports burst data transfers and efficient DRAM access for systems using external memory.
• Dynamic Bus Sizing — Direct interface to 8-, 16- and 32-bit devices via automatic bus sizing on a cycle-by-cycle basis.
• Nonmultiplexed Address/Data Buses — Complete 32-bit address and data buses for straightforward external device interfacing.
• Registers and Control — Sixteen 32-bit general-purpose registers, two 32-bit supervisor stack pointers, eight special-purpose control registers, and two access control registers for cacheability protection.
• Coprocessor Support — Complete support for M68000 coprocessors via the standard coprocessor interface.
• Addressing Range — 4-Gbyte direct addressing range for large memory maps.
• Interfaces — Includes SCI (Serial Communications Interface) for serial connectivity in embedded designs.
• Package and Mounting — 132-CQFP (24×24) surface-mount package for compact PCB layouts.
• Electrical and Environmental — 5 V I/O voltage and RoHS compliant. Operating temperature range: 0 °C to 70 °C.

Typical Applications

• Embedded Control Systems — Used where a 32-bit embedded controller with integrated caches and advanced bus control is required for control and processing tasks.
• Migration from M68000-family Designs — Provides object-code compatibility with MC68020/MC68030 and earlier M68000 microprocessors to ease software migration.
• Systems with Multi-Width Memory — Ideal for designs that require direct interfacing to 8-, 16-, and 32-bit memory or peripheral devices thanks to dynamic bus sizing.
• Designs Requiring External DRAM Efficiency — Burst-mode bus interface supports efficient DRAM access patterns in memory-backed embedded systems.

Unique Advantages

• Highly Integrated Controller: Combines the MC68030 integer unit, instruction and data caches, access control unit and bus controller on a single die to reduce system complexity.
• Flexible Memory Interfacing: Dynamic bus sizing and burst transfers simplify connection to a variety of external memory devices and peripherals.
• Clear Migration Path: Object-code compatibility with earlier M68000-family processors eases software reuse and migration.
• Compact Surface-Mount Package: 132-CQFP (24×24) surface-mount packaging supports compact PCB layouts while providing a full 32-bit nonmultiplexed bus.
• Standards-Based Connectivity: SCI interface and full coprocessor support allow integration into established embedded architectures.
• Regulatory Compliance: RoHS compliant to meet typical environmental requirements for modern electronics.
