Product Overview The Intel386™ DX, EX, and SX embedded processors are based on the Intel386 architecture. All have 32-bit cores, and enhanced functionality for the embedded processor market. The static Intel386 EX microprocessor is designed for embedded applications that require high integration and low power. Key features include: PC compatibility, power management, low-voltage operation, and on-chip integration of numerous common peripherals such as interrupt controllers, chip selects, counters and timers. The static Intel386 SX microprocessor is a pin-for-pin replacement for the dynamic Intel386 SX processor. The static design features clock freeze mode, and higher speed operation. The dynamic Intel386 SX microprocessor is an entry-level processor with a 16-bit external data bus and a 24-bit external address bus. It provides the performance benefits of a 32-bit architecture with the cost savings of a 16-bit hardware system. The dynamic Intel386 DX microprocessor is designed for single-user, multi-tasking applications. The 32-bit registers and data paths support 32-bit addresses and data types. It addresses 4 gigabytes of physical memory, and 64 terabytes of virtual memory. It offers a 50% performance increase over the Intel386 EX and SX processors. The 80386SXTA, commonly called 80386SSX, is designed for the benefits of static design and offers high speeds and extended temperatures. Intel386™ processors have provided the computer industry with reliability and high performance. Initially built as the host CPU for PCs, these processors are still readily available and continue to provide high performance, 32-bit processing power for embedded applications. Thanks to a static Intel386 processor core design, the pin-for-pin compatible family enables higher performance and lower power and voltage capabilities for embedded systems. Intel386™ Integrated Processor Family The Intel386 EX processor is an integrated processor for embedded applications. Intel based the EX on the same static Intel386 processor 32-bit core, and incorporated PC-compatible and traditional embedded peripherals to provide a high-performance, integrated embedded solution.
