CompactFlash/PCMCIA Host Controller with EXCA Registers

Key Features

• 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.
