GENERAL DESCRIPTION

The

microprocessor with dual CAN 2.0B controllers. The

redesigned

instructions up to 3X faster than the original for the

same crystal speed. The DS80C390 supports a

maximum crystal speed of 40MHz, resulting in

apparent

(approximately 2.5X). An optional internal frequency

multiplier allows the microprocessor to operate at full

speed with a reduced crystal frequency, reducing

EMI. A 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.
