The DS80C390 is a fast 8051-compatible
microprocessor with dual CAN 2.0B controllers. The
redesigned processor core executes 8051
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 execution speeds of 100MHz
(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.
