Overview
GENERAL DESCRIPTION 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.
The High-Speed Microcontrolle...
