GENERAL DESCRIPTION
The
élanSC300 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 élanSC300 microcontroller from AMD is part of the
growing élan family of mobile computing products,
which leverage existing AMD core modules. The
élanSC300 microcontroller demonstrates the feasibil-
ity of constructing highly integrated components built
from standard cores and getting these products to mar-
ket 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 microcon-
troller, see the élan
TM
SC300 Microcontroller Program-
mer’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 control-
ler that supports local or ISA bus; a serial port controller
that is 16450 UART compatible; a bidirectional EPP-
compliant parallel port; a 146818A-compatible
real-time clock; internal phase-locked loops for clock
generation; and standard PC logic chips (8259A,
8237A, and 8254).
The élanSC300 microcontroller’s true static design
and low operating voltage enable battery-powered op-
eration and lower weight for embedded PC applica-
tions. The internal core of the élanSC300
microcontroller operates at 3.3 V and the I/O pads
allow either 3.3 V or 5 V operation. Lowering typical op-
erating voltage from 5 V to 3.3 V can dramatically re-
duce power consumption.
Functionally, the élanSC300 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 élanSC300 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
élanSC300 microcontroller.
