GENERAL DESCRIPTION

The DS80C400 is a fast 8051-compatible

microcontroller that executes instructions up to three

times faster than an original 8051 at the same crystal

speed. Its maximum system-clock frequency of

75MHz results in a minimum instruction cycle time

of 54ns. Access to large program or data memory

areas is simplified with a 24-bit addressing scheme

that supports up to 16MB of flat memory. To

accelerate data transfers between the microcontroller

and the 16MB memory map, the DS80C400 provides

four data pointers, each of which can be configured

to automatically increment or decrement upon

execution of certain data pointer-related instructions.

The mircocontroller’s hardware math accelerator

further increases the speed of 32-bit and 16-bit

multiply and divide operations as well as high-speed

shift, normalization, and accumulate functions.
