R5C853 will be Non-promotion/Discontinued Products.
We recommend new or existing products to the customers.
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
Power Supply Voltage: 3.3V±0.3V
Operating Ambient Temperature Range: 0~70°C
The R5C853 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.
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.
The internal regulator allows 3.3V single power operation.
