GENERAL DESCRIPTION
The Élan™SC400 and ÉlanSC410 microcontrollers
are the among the latest in a series of E86™ family
microcontrollers, which integrate proven x86 CPU
cores with a comprehensive set of on-chip peripherals
in a 0.35-micron process.
With its low-voltage Am486® CPU core and ultra-small
form factor, the ÉlanSC400 microcontroller is highly op-
timized for mobile computing applications. The
ÉlanSC410 microcontroller is targeted specifically for
embedded systems.
The ÉlanSC400 and ÉlanSC410 microcontrollers
combine a 32-bit, low-voltage Am486 CPU with a
complete set of PC/AT-compatible peripherals, along
with the power management features required for
battery operation.
A feature comparison of the two microcontrollers is
shown in Table 1 on page 3.
The ÉlanSC400 and ÉlanSC410 microcontrollers use
the industry-standard 486 microprocessor instruction
set. All software written for the x86 architecture family
is compatible with the ÉlanSC400 and ÉlanSC410
microcontrollers.
Leveraging the benefits of the x86 desktop computing
environment, the ÉlanSC400 and ÉlanSC410 microcon-
trollers integrate all of the common logic and I/O func-
tionality associated with a PC/AT computing system into
a single device, eliminating the need for multiple periph-
eral chips. Fully integrated PC/AT-compatible peripher-
als include two 8259A-compatible programmable
interrupt controllers (PICs), two 8237A-compatible DMA
controllers, an 8254-compatible timer, a 16550 UART,
an IrDA controller, VL-bus and ISA bus controllers, a
real-time clock (RTC), and Enhanced Parallel Port
(EPP) mode for the parallel port.
The ÉlanSC400 and ÉlanSC410 microcontrollers are
based on a fully static design and include an advanced
power management unit. Operating voltages are
2.7 V–3.3 V with 5-V-tolerant I/O pads. Orderable in
both 33-MHz, 66-MHz, and 100-MHz peak processor
speeds, the product is available in the ultra-small
292 ball grid array (BGA) package.
