GENERAL DESCRIPTION
The ÉlanSC300 microcontroller is a highly integrated, l o w -v o l t a g e , single-chip implementation of the Am386 SXLV microprocessor plus most of the additional logic needed for an AT-compatible personal computer. It is ideal for embedded PC applications, such as poi nt -of-sal e equipment, web appliances, industrial controls, and communication equipment. The ÉlanSC300 microcontroller from AMD is part of the gro wi ng Élan family of mobile computing products, w h i c h leverage existing AMD core modules. The ÉlanSC300 microcontroller demonstrates the feasibility of constructing highly integrated components built from standard cores and getting these products to market quickly. The ÉlanSC300 microcontroller does this by combining an Am386SXLV low-voltage microprocessor core with a memory control unit, a Power Management Unit (PMU), and the bus control and peripheral control logic of a PC/AT-compatible computer. For more information about the Am386 microprocessors, see the Am386®SX/SXL/SXLV Data Sheet, order #21020 and the Am386®DX/DXL Data Sheet, order #21017. For more information about the ÉlanSC310 microcontroller, see the ÉlanTMSC300 Microcontroller Programmer 's Reference Manual, order #18470. The ÉlanSC300 microcontroller includes a memory controller that supports up to 16 Mbyte of DRAM, Flash or ROM; power management functions; a bus controller that supports local or ISA bus; a serial port controller that is 16450 UART compatible; a bidirectional EPPc o m p l i a n t parallel port; a 146818A-compatible real-time clock; internal phase-locked loops for clock g e n e r a t i o n ; and standard PC logic chips (8259A, 8237A, and 8254). The ÉlanSC300 microcontroller's true static design and low operating voltage enable battery-powered operation and lower weight for embedded PC applications. The internal core of the ÉlanSC300 mi croco nt rol l er operates at 3.3 V and the I/O pads allow either 3.3 V or 5 V operation. Lowering typical operating voltage from 5 V to 3.3 V can dramatically reduce power consumption. Functionally, the ÉlanSC300 microcontroller is a 100% DOS /W i nd ow s-co mp at i bl e, PC/AT-compatible computer on a chip that is designed to furnish the customer with a high-performance, low-power system solution, p r o v i d i n g state-of-the-art power management in a small physical footprint. The ÉlanSC300 microcontroller is available in both 25a nd 33-MHz versions, in a 208-lead Plastic Shrink Quad Flat Pack (QFP) (PQR package) and a 208-lead Thin Quad Flat Pack (TQFP) (PQL package).
Note: Unless specified otherwise, the timings in this data sheet are based on the 33-MHz version of the ÉlanSC300 microcontroller.
