R5C833 Specifications
|
 |
|
| |
The R5C833 is a single chip solution offering five PCI functions (a PCI
bus bridge to an IEEE1394, an SD Card, a MultiMediaCard, a Memory Stick, and an xD Picture Card). 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 R5C833 uses an internal PLL for the high speed Media clock and it is yielding the high performance.
Pin-out compatible with the R5C832

Power Supply Voltage: 3.3V±0.3V
Operating Ambient Temperature Range: 0~70°C |
| Specializing in supporting only Flash Memory Cards, the R5C833 comes in smaller package
(128-pin TQFP), compared with our existing products (the R5C841/842). The R5C833 is ideal for
devices that
require miniaturization. |
| The R5C833 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 R5C833 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. |
