Description

General part information

DS80C390 Series

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.TheHigh-Speed Microcontroller User's Guideand theHigh-Speed Microcontroller User's Guide: DS80C390 Supplementshould be used in conjunction with this data sheet.
