The MC68302AG33C is an M68000-core microprocessor IC designed for embedded systems. It features a single M68000 core with an 8/16-bit bus implementation and a rated operating frequency of 33 MHz.

Built with integrated communications co-processing and DRAM controller support, the device targets embedded applications that require a compact, surface-mount MPU in a 144-LQFP (20x20) package while operating from a 5 V IO supply within a 0 °C to 70 °C range.

Key Features

• Core & Performance Single M68000 core with an 8/16-bit bus and a clock rate of 33 MHz; timing is characterized at 33 MHz with a cycle period (tcyc) of 30 ns and clock pulse widths (tcl, tch) of 15 ns.
• Co-Processing & Communications Includes communications-focused co-processors and a RISC CPM to assist system-level communications tasks and offload specific processing functions.
• Memory Interface Integrated DRAM controller(s) to support external dynamic memory configurations for system-level data buffering and code storage.
• Interfaces Additional interface support includes GCI for system connectivity and control.
• Power & IO Operates with a 5 V IO voltage, suitable for designs standardized on 5 V signaling.
• Package & Mounting Supplied in a 144-LQFP package (20x20), optimized for surface-mount assembly and compact board-level integration.
• Deterministic Timing Comprehensive timing parameters are provided for 33 MHz operation (examples: 30 ns cycle period, 15 ns clock pulse width, and documented address/data and control timing windows), enabling predictable interface and bus design.
• Environmental Compliance RoHS compliant, supporting regulatory-driven material requirements for electronics manufacturing.
• Operating Range Rated for operation from 0 °C to 70 °C, suitable for commercial-temperature embedded deployments.

Typical Applications

• Embedded Communications Controllers — Use the integrated communications co-processor and CPM to implement protocol handling and interface tasks in embedded communication products.
