See EP510 for CompactFlash/PCMCIA Host Controller


  • Compliant with PC Card Standard 8.0, PCMCIA 2.1/JIEDA 4.2 and CompactFlash 1.4.
  • Allows host CPU to access CompactFlash, PC Card/PCMCIA devices.
  • 82365SL-compatible register set, EXCA compatible.
  • Access management and control through easy to use internal registers.
  • Simple user interface optimized for on-chip bus connection.
  • Option to integrate with other CPU bus slaves to support direct access by various CPU's including PowerPC, MPC860, ARM, SH2/3/4, MIPS, and ARC microprocessors.
  • Supports attribute memory access, common memory access, IO access and IDE mode access in both PCMCIA card and Compact Flash modes.
  • Converts 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.
  • CPU may operate at higher frequency while the card interface is based on 33Mhz input clock.
  • Card voltage sense support.
  • Supports TPS2211A power switch and option to support TPS2226A.
  • Single card interface design, extendable to dual card interface.
  • Designed for ASIC and PLD implementations.
  • Fully static design with edge triggered flip-flops.
