EP510 CompactFlash/PCMCIA Host Controller

See EP512 for CompactFlash/PCMCIA Host Controller with EXCA registers

Features

• 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.
