ELANSC400 Datasheet, PDF (1/132 Pages) Advanced Micro Devices – Single-Chip, Low-Power, PC/AT-Compatible Microcontrollers

Élan™SC400 and ÉlanSC410
Single-Chip, Low-Power,
PC/AT-Compatible Microcontrollers
DISTINCTIVE CHARACTERISTICS
Élan™SC400 and ÉlanSC410
Microcontrollers
s E86^TM family of x86 embedded processors
– Offers improved time-to-market, software
migration, and field-proven development tools
s Highly integrated single-chip CPU with a complete
set of common peripherals
– Accelerates time-to-market with simplified
hardware
– Low-power 0.35-micron process technology
– Single chip delivers smallest system form factor
– 33-MHz, 66-MHz, and 100-MHz operating
frequencies
s Am486^® CPU core
– Robust Microsoft^® Windows^® compatible CPU
– 8-Kbyte write-back cache for enhanced
performance
– Fully static design with System Management
Mode (SMM) for power savings
s Comprehensive power management unit
– Seven modes of operation allow fine-tuning of
power requirements for maximum battery life
– Provides a superset of APM 1.2 features
s Glueless burst-mode
ROM/Flash memory/SRAM interface
– Reduces system cost by allowing mask ROM and
Flash memory at the same time with three ROM/
Flash memory/SRAM chip selects
s Glueless DRAM controller
– Allows mixed DRAM types on a per-bank basis to
reduce system cost
s VESA Local (VL) bus and ISA bus interface
– Reduces time-to-market with a wide variety of off-
the-shelf companion chips
s Standard PC/AT system logic
(PICs, DMACs, timer, RTC)
– DOS, ROM-DOS, Windows, and industry-
standard BIOS support
– Leverages the benefits of desktop computing
environment at embedded price points
s Bidirectional parallel port with Enhanced
Parallel Port (EPP) mode
s 16550-compatible UART
s Infrared port for wireless communication
– Standard and high-speed
s Keyboard interface
– Matrix keyboard support with up to 15 rows and 8
columns
– SCP-emulation mode for PC/AT and XT
keyboard support
ÉlanSC400 Microcontroller Only
The ÉlanSC400 microcontroller includes the following
additional features designed specifically for mobile
computing applications. The ÉlanSC410 microcontrol-
ler does not include these features.
s Dual PC Card (PCMCIA Version 2.1) controller
supports 8- or 16-bit data bus
– End-user (after-market) system expansion
– ExCA-compliant, 82365-register set compatible
– Leverages off-the-shelf card and socket services
– Supports DMA transfers between I/O PC cards
and system DRAM
s LCD graphics controller
– Supports monochrome and 4-bit color Super
Twisted Nematic (STN) LCDs
– Unified Memory Architecture (UMA) eliminates
separate video memory
