DescriptionAMD Elan Am386SC300 Series HIghly Inegrated, Low-Power, 32-bit Microprocessors and System Logic
OverviewThe ÉlanTM Am386 ® SC300 device is a highly integrated, low-voltage, single-chip implementation of the Am386SXLV microprocessor plus most of the additional logic needed for an AT-compatible personal computer. It is ideal for palm-top computers and Personal Digital Assistants (PDAs). It combines an Am386SXLV low-voltage microprocessor core with a memory control unit, a power management unit (PMU), and the standard system, ISA bus, and peripheral control logic of a PC/AT-compatible computer. In addition, the chip includes a 146818A-compatible real-time clock, internal phase locked loops for clock generation, and a local bus controller. The Am386SC300 microprocessor from AMD® is the first in a family of mobile computing products from the Embedded Processor Division (EPD). EPD provides standard products for the handheld, palm-top, and PDA computer markets, leveraging AMD core modules. The Am386SC300 microprocessor demonstrates the feasibility of constructing highly integrated components built from standard cores and getting these products to market quickly.The Am386SC300 microprocessor has integrated all the system and peripheral control logic of a chipset for a portable computer, plus built-in 16450 UART, two PCMCIA Version 2.1 slots, power management functions, memory controller, bus controller, standard PC logic chips (8259A, 8237A, and 8254), and a built-in CGA-compatible LCD controller. The Élan device’s true static design and low operating voltage enable longer battery life and lower weight for handheld applications. The internal core of the Am386SC300 microprocessor 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 increase battery life. Functionally, the Élan device is a PC/AT-compatible computer on a chip that is designed to furnish the customer with a high-performance, low-power system solution, providing state-of-the-art power management in a small physical footprint. The Élan Am386SC300 microprocessor is available in both 208-pin Plastic Quad Flat Pack (PQFP) and Thin Quad Flat Pack (TQFP) packages.
