MC68302EH20C

The MC68302EH20C is an M68000-core microprocessor IC optimized for embedded applications. It integrates a single M68000 core with 8/16-bit bus capability and runs at 20 MHz, delivering deterministic processing for control and communications functions.

Designed for system-level integration, the device provides communications-oriented co-processor support and DRAM memory controller functionality, packaged in a 132-pin PQFP surface-mount package and specified for 0 °C to 70 °C operation. The part is RoHS compliant and uses a +5 V I/O supply.

Key Features

• Core M68000 core architecture with a single processing core supporting 8/16-bit bus operation for legacy and mixed-width interfaces.
• Clock Speed 20 MHz operating speed suitable for deterministic embedded control and communications tasks.
• Co-Processor / Communications Communications-oriented co-processor support including a RISC CPM to assist protocol and data handling workloads.
• Memory Controller Integrated DRAM controller functionality to interface with external dynamic RAM for system memory requirements.
• Voltage and I/O +5 V I/O supply voltage for compatibility with legacy embedded systems and typical 5 V logic domains.
• Interfaces Additional interface support listed as GCI to facilitate system connectivity.
• Package & Mounting 132-pin PQFP (46 × 46 mm) surface-mount package with bumpered BQFP designation for board-level reliability and density.
• Operating Range Rated for 0 °C to 70 °C operation for standard commercial-temperature embedded environments.
• Environmental Compliance RoHS compliant to support regulatory requirements for lead-free assemblies.

Typical Applications

• Embedded Control Use as a general-purpose embedded MPU for control tasks where an M68000 core and deterministic timing are required.
• Communications Modules Suited for communications-oriented subsystems that can leverage the on-chip communications co-processor and GCI interface.
• System Memory Control Integration in designs that require DRAM interfacing managed by an on-chip memory controller.
• Industrial and Commercial Electronics Deployment in commercial-temperature embedded products where a 5 V I/O MPU in a compact PQFP footprint is appropriate.

Unique Advantages

• Established M68000 Architecture: Leverages the widely recognized M68000 core for predictable instruction behavior and software compatibility within that architecture family.
• Integrated Communications Support: On-chip communications co-processor (RISC CPM) reduces external controller requirements for protocol handling and offloads communications tasks from the main core.
• On-Board DRAM Control Capability: Built-in DRAM controller simplifies memory subsystem design and reduces external glue logic.
• Compact, Surface-Mount Package: 132-pin PQFP (46 × 46 mm) provides a high pin-count solution in a standard SMT footprint for space-conscious embedded boards.
• RoHS Compliant: Meets lead-free assembly requirements for modern manufacturing processes.
