R68000

The R68000 is designed as 16-bit microprocessing unit (MPU) which offer seventeen 32-bit registers in addition to the 32-bit program counter and a 16-bit status register which designed for high performance where operational computation and versatility is required.

The R68000 has many features. The first one is 16M byte (8M word) linear addressing range. The second one is 14 operand addressing modes. The third one is 56 powerful instruction types. The fourth one is instruction set supports structured high-level languages. The fifth one is pipelining instruction execution. The sixth one is 32-bit program counter. The seventh one is 16-bit data bus. The eighth one is 23-line address bus. The ninth one is 32-bit data and address registers include eight general purpose data registers and seven address registers and two stack pointers (user, supervisory). The tenth one is all 17 registers can be index registers. The eleventh one is memory mapped peripheral devices. The twelfth one is vector generated exception processing. The thirteenth one is seven unique autovectors for interrupt service routines. And so on. That are all the main features.

Some absolute maximum ratings of R68000 have been concluded into several points as follow. The first one is about its supply voltage which would be from -0.3V to +7.0V. The second one is about its input voltage which would be from -0.3V to +7.0V. The third one is about its storage temperature range which would be from -55°C to +150°C. It should be noted that stresses above those listed under absolute maximum ratings may cause permanent damage to the device. This is a stress rating only and function operation of the device at these or any other conditions above those indicated in other sections is not implied. And so on.
