communication cards, etc. The high performance and capability of the CardBus interface will
enable the new development of many new functions and applications.
The R5C554 CardBus controller is compliant with the latest ACPI-PCI Bus Power
Management interface Specification. It supports all four power states and the PME# function
for maximum power savings and ACPI compliance. Additional compliance to On Now Power
Management includes D3 cold state support, paving the way for low sleep state power
consumption and minimized resume times. To allow host software to reduce power
consumption further, the R5C554 provides a power-down mode in which internal clock
distribution and the PC Card socket clocks are stopped. An advanced CMOS process is also
used to minimize system power consumption.
The R5C554 single PCMCIA socket supports the 3.3V/5V 8/16-bit PC Card R2 cards or 32-bit
CardBus R3 cards. The R2 card support is compatible with the Intel 82365SL PCIC controller,
and the R3 card support is fully compliant with the 2000 PC Card Standard CardBus
specification. The R5C554 is an additional buffer chip for the PC Card socket interface. In
addition, the R5C554 supports dynamic PC Card hot insertion and removal, with auto
configuration capabilities.
The R5C554 is fully complains with the 33Mhz PCI Bus specification, v2.2. It supports a
master device with internal CardBus direct data transfer. The R5C554 implements FIFO data
buffer architecture between the PCI bus and CardBus socket interface to enhance data
transfers to CardBus Devices. The bi-directional FIFO buffer permits the R5C554 to accept
data from a target bus (PCI or CardBus interface) while simultaneously transferring data. This
architecture not only speeds up data transfers but also prevents system deadlocks.
The R5C554 is a PCMCIA R2/CardBus controller, providing the most advanced design
flexibility for PC Cards that interface with advanced notebook designs.
