Philips SCC68070

The SCC68070 is a Philips Semiconductors-branded, Motorola 68000-based 16/32-bit processor produced under license. While marketed externally as a high-performance microcontroller, it has been almost exclusively used combined with the Philips SCC66470 VSC (Video- and Systems Controller) in the Philips CD-i interactive entertainment product line.

Additions to the Motorola 68000 core include:

Differences from the Motorola 68000 core include these:

While the SCC68070 is mostly binary compatible with the Motorola 68000, there is no equivalent chip in the Motorola 680x0 series. In particular, the SCC68070 is not a follow-on to the Motorola 68060.

Even though the SCC68070 is a 32-bit processor internally, it has a 24-bit address bus, giving it a theoretical 16MB maximum RAM. However, this is not possible, as all of the on-board peripherals are mapped internally.
