R5C853 Specifications

The R5C853 is a single chip solution offering seven PCI functions (a PCI bus bridge to a PC Card, an IEEE1394, an SD Card, a MultiMediaCard, a Memory Stick, an xD Picture Card, and a Smart Card via a PC Card) with an ExpressCard (USB Interface Type) switch. Almost all the Flash Memory Cards currently in the market, allowing system designers to flexibly configure systems necessary to interface with multiple Flash Memory Cards.

The R5C853 uses an internal PLL for the high speed Media clock and it is yielding the high performance.

Pin-out compatible with the R5C853: R5C803 , R5C811, R5C841 , R5C843 , R5C847

High Performance

The R5C853 uses an internal PLL for the high speed Media clock. and it is yielding the high performance.

Low Power Consumption

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

SD Card/SDIO/MMC Automatic Configuration

The R5C853 supports SD/SDIO/MMC automatic configuration functionality, which makes it possible to support SD/SDIO/MMC in the same slot by use of RICOH's dedicated MMC driver.

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.
