2.3.9 RICOH R5C551 IEEE1394A Host & PCMCIA Controller
The 5C551 is the single chip solution offering PCI bus-PC Card bridges and PCI bus-
IEEE 1394 OHCI bridge with integrated PHY. The R5C551 is compliant with th e latest
specification in both PC card and IEEE 1394.
The R5C551 has two PCI functions compliant, the PC card interface and the IEEE1394
interface. The PC card controller of the R5C551 is compliant with PC Card Standard
Release 7.0. The R5C551 provides features that make it the best choice for bridging
between the PCI bus PC Cards, and supports any combination of 16-bit (Card-16) and
CardBus (Card-32) PC Cards in one socket, powered at 5V or 3.3V, as required.
The R5C551’s 16-bit card control register is compatible with the Intel 82365SL and
Ricoh’s RF5C396/366 in order to maintain backward compatibility with the existing 16-bit
PC Card compliant with PCMCIA2.1/JEIDA4.2. All PC card interface signals are
individually buffered to allow direct connection to CardBus and Hot Insertion/Removal
without external buffers. The R5C551 also allows direct connection to PCI bus.
The R5C551 provides the IEEE1394 OHCI-Link and two ports the IEEE1394 PHY that are
compliant with the IEEE1394 -1995, IEEE1394a-2000 and the latest 1394 OHCI
specifications (Release 1.1/1.0). The R5C551 data rate is capable of 100/200, and
400Mbits per second. The R5C551 has the large FIFO buffer and the DMA engine, which
work independently to achieve the high speed transmission rate. The R5C551 is
compliant with the latest PCI Bus Power Management Specification, and provides several
low-power modes that enable the host power system to further reduce power consumption.
