R5C841/R5C842 Specifications

The R5C841 (1slot)/ 842 (2 slots) is a single chip solution offering PCI functions (PCI bus bridge to a PC Card, an IEEE1394, an SD Card, a Memory Stick, and an xD Picture Card) with an ExpressCard (USB Interface type) switch.
In addition to the functions of our existing products (R5C821/822), support for an xD Picture Card has been implemented into the R5C841/842. Therefore, adopting the R5C841/842 makes it possible to support almost all the Flash Memory Cards currently in the market.
The RICOH PC Card/Flash Memory Card/IEEE1394 Controller series has got a variable lineup with different slot counts and packages. The R5C841/842 can share a PCB (printed circuit board) with the R5C811/812.

IEEE1394 Interface

The R5C841/842 has a 2-port 1394 Cable Interface, whose transfer rates are 100/200/400 Mbps, and independent high-capacity FIFO buffers and DMA engines. Also, the R5C841/842 supports two types of data transfer: Asynchronous and Isochronous.

Low Power Consumption

Due to the originally developed hardware design, power consumption during Suspend mode has been drastically reduced.

Internal Regulator

The internal regulator allows 3.3V single power operation.

Applications

  • Personal computers (laptop, palmtop, stylus-operated, or tablet PC)
  • Docking stations
  • Car navigation systems
  • PDA
  • Systems with PC Card slots, etc.
