DESCRIPTION

· The DS80C390 is a high-speed 8051-compatible microprocessor with dual CAN 2.0B controllers.

· It executes 8051 instructions up to 3X faster than the original at the same crystal speed.

· Supports a maximum crystal speed of 40MHz, achieving apparent execution speeds of 100MHz.

· Features an internal frequency multiplier to reduce EMI by operating at full speed with a reduced crystal frequency.

· Includes a hardware math accelerator for faster 32-bit and 16-bit multiply, divide, shift, normalization, and accumulate operations.

FEATURES

· 80C52 compatible architecture.

· 4kB internal SRAM usable as program/data/stack memory.

· Two full-function CAN 2.0B controllers.

· Two full-duplex hardware serial ports.

· Programmable IrDA clock.

· 16 interrupt sources with six external.

· Available in 64-pin LQFP and 68-pin PLCC packages.

APPLICATIONS

· Industrial controls.

· Agricultural equipment.

· Factory automation.

· Gaming equipment.

· Medical equipment.

· Heating, ventilation, and air conditioning systems.
