The ÉlanSC400 microcontroller includes the following
additional features designed specifically for mobile
computing applications. The ÉlanSC410 microcontrol-
ler does not include these features.
– Fully static design with System Management
Mode (SMM) for power savings
■ Comprehensive power management unit
■ Dual PC Card (PCMCIA Version 2.1) controller
– Seven modes of operation allow fine-tuning of
power requirements for maximum battery life
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
– Provides a superset of APM 1.2 features
■ Glueless burst-mode
ROM/Flash memory/SRAM interface
– Supports DMA transfers between I/O PC cards
and system DRAM
– Reduces system cost by allowing mask ROM and
Flash memory at the same time with three ROM/
Flash memory/SRAM chip selects
■ LCD graphics controller
– Supports monochrome and 4-bit color Super
Twisted Nematic (STN) LCDs
■ Glueless DRAM controller
– Allows mixed DRAM types on a per-bank basis to
reduce system cost
– Unified Memory Architecture (UMA) eliminates
separate video memory
■ VESA Local (VL) bus and ISA bus interface
– Reduces time-to-market with a wide variety of off-
the-shelf companion chips
