DCD’s latest IP Core is a modern incarnation of CPU32+ based on M68020, which are no longer available, yet still in use in millions of projects. What differs D68000-CPU32+ from other similar solutions is automatic byte alignment feature that is not available in CPU32. This feature allows both 16 and 32-bit data to be transferred at any odd addresses. The CPU32+ automatically adjust required bus cycles and if it’s not enough, it operates also on 32-bit external operands with one bus cycle.


The engineering team at Digital Core Design in Poland have introduced the newest version of the classic MC68020 based 16/32-bit microprocessor. The D68000-CPU32+ is the industry’s low cost 32-bit MCU, offering a low-cost entry point combined with effective performance.

The CPU32+, an enhanced version of the classic 68020, is designed to seamlessly replace outdated CPU32+ components that are no longer available in the market. The D68000-CPU32+ serves as an ideal solution for systems with existing CPU32+ architecture.

Key Features of the D68000-CPU32+ include:

  • Versatile Data Bus Transfers: The CPU32+ supports 8-, 16-, and 32-bit data transfers on the bus to any address, including Byte misaligned addressing, providing unparalleled flexibility in data handling.
  • Dynamic Bus Sizing: The IP core incorporates dynamic bus sizing for byte and word, allowing for efficient and adaptive data processing tailored to specific application requirements.
  • 32-Bit Data and Program Bus: With a 32-bit data and program bus, the CPU32+ ensures enhanced performance and seamless integration with modern systems, while maintaining compatibility with legacy components.
  • Extended Memory Support: The D68000-CPU32+ is engineered to support up to 4 GB of both data and program memory, meeting the demands of contemporary applications with expansive memory requirements.

The D68000-CPU32+ represents a significant leap forward in our commitment to providing robust solutions for legacy systems,” said Tomasz Krzyżak, CTO at Digital Core Design. “This IP core not only ensures the continued operation of systems reliant on CPU32+ architecture but also introduces advanced features to meet the evolving needs of our clients.

Digital Core Design remains dedicated to delivering cutting-edge solutions that bridge the gap between legacy technologies and the demands of modern computing. The D68000-CPU32+ is poised to become an indispensable component for engineers and developers seeking a reliable and efficient replacement for obsolete CPU32+ based parts.
