Élan™SC310 Microcontroller Data Sheet

PREL IMINARY

GENERAL DESCRIPTION

The ÉlanSC310 microcontroller is a highly integrated,

low-voltage, single-chip implementation of the

Am386SXLV microprocessor plus most of the addi-

tional logic needed for an AT-compatible personal com-

puter. It is ideal for embedded PC applications, such as

point-of-sale equipment, web appliances, industrial

controls, and communication equipment.

The ÉlanSC310 microcontroller from AMD is part of the

growing Élan family of mobile computing products,

which leverage existing AMD core modules. The

ÉlanSC310 microcontroller demonstrates the feasibil-

ity of constructing highly integrated components built

from standard cores and getting these products to mar-

ket quickly.

The ÉlanSC310 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 A m386 mic r opr oc esso r s , s ee the

Am386®SX/SXL/SXLV Data Sheet, order #21020 and

the

AM386®DX/DXL Data Sheet, order #21017.

For more information about the ÉlanSC310 microcon-

troller, see the

ÉlanTMSC310 Microcontroller Program-

mer’s Reference Manual, order #20665.

The ÉlanSC310 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 bidirec-

tional EPP-compliant parallel port; a 146818A-compat-

ible real-time clock; internal phase-locked loops for

clock generation; and standard PC logic chip functions

(8259A, 8237A, and 8254).

The ÉlanSC310 microcontroller’s true static design

and low operating voltage enable battery-powered op-

eration and lower weight for embedded PC applica-

t i ons. T h e in ter n al cor e of t he ÉlanSC 310

microcontroller 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 re-

duce power consumption.

Functionally, the ÉlanSC310 microcontroller is a 100%

DOS/Windows-compatible, PC/AT-compatible com-

puter 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 ÉlanSC310 microcontroller is available in both 25-

and 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

ÉlanSC310 microcontroller.
