Philips 68070
From Wikipedia, the free encyclopedia
The 68070 was a Philips-branded 68000-based Microcontroller with built in DMA controller, minimal MMU, I²C bus controller and other enhancements. Not all the differences were enhancements: it had one less arithmetic unit than the 68000, so that, for example, operations involving an operand in memory requiring address calculation took longer on the 68070 than the 68000, since the same ALU had to do first the effective address calculation and then the operation. It was used in the CD-i.
Despite the name, this chip was not part of the Motorola 680x0 series - Motorola never produced a 68070.
