R5C847 Specifications
|
 |
|
| |
The R5C847 is a single chip solution offering six PCI functions (a PCI
bus bridge to a PC Card, an IEEE1394, an SD Card, a MultiMediaCard, a Memory Stick, and an xD Picture 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 R5C847 uses an internal PLL for the high speed Media clock and it is yielding the high performance.
Pin-out compatible with the R5C847: R5C803 , R5C811, R5C841 , R5C843 , R5C853 |

|
| The R5C847 uses an internal PLL for the high speed Media clock. and it is yielding
the high performance. |
| Due to the originally developed hardware design, power consumption during Suspend mode
has been drastically
reduced. |
SD Card/SDIO/MMC Automatic Configuration
|
|
|
|
| The R5C847 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. |
| The internal regulator allows 3.3V single power operation. |
