GENERAL DESCRIPTION

FEATURES

The DS80C390 is

fast 8051-compatible

ꢀ

80C52 Compatible

microprocessor with dual CAN 2.0B controllers. The

High-Speed Architecture

4kB Internal SRAM Usable as Program/

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

Data/Stack Memory

ꢀ

Enhanced Memory Architecture

Two Full-Function CAN 2.0B Controllers

Two Full-Duplex Hardware Serial Ports

Programmable IrDA Clock

High Integration Controller

16 Interrupt Sources with Six External

Available in 64-Pin LQFP, 68-Pin PLCC

apparent

execution

speeds

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.

See page 29 for a complete list of features.
