See EP512 for CompactFlash/PCMCIA Host Controller with EXCA registers


  • Compliant with PC Card Standard 8.0, PCMCIA 2.1/JIEDA 4.2 and Compact-Flash 1.4
  • Allows host bus devices to access CompactFlash and PC Card/PCMCIA devices.
  • Simple user interface optimized for on-chip bus connection.
  • Dual clock design allows the user interface and the Card interface to operate at different clock domains.
  • User interface supports 32-bit and 64-bit data.
  • In PC Card/PCMCIA mode, supports attribute memory access, common memory access and IO access.
  • In CompactFlash mode, supports attribute memory access, common memory access, IO access and IDE mode access.
  • Converts 64/32-bit CPU access to multiple 8-bit or 16-bit accesses.
  • Supports burst access by CPU. Burst access dispatched as multiple single accesses to the CompactFlash/PCMCIA interface.
  • Direct mapping of host address space to card address space.
  • CPU may operate at higher frequency while the card interface operates at lower frequency.
  • Designed for ASIC and FPGA implementations.
  • Fully static design with edge triggered flip-flops.

Differentiating Features

  • CPU or generic user interace selection.
  • External power switch support.
  • Dual card interface.
  • 82365SL compatible and EXCA register set.
