| R5U230 Series |
PCI Express-Flash Memory Card Controller |
||
The R5U230 is a multi-function PCI Express controller that integrates 4 PCI Express functions (1-lane PCI Express to an IEEE1394, an SD/MMC Card, a Memory Stick and an xD Picture Card) into a single chip. |

| Power Supply Voltage: 3.3V±0.3V | ||
| Operating Ambient Temperature Range: 0~70°C | ||
| Low Power Consumption | ||
| ● Ricoh’s proprietary power save mode, such as supporting ASPM function and CLKREQ#, enables the reduction of power consumption. | ||
| Internal Regulator & Power-Switch | ||
| ● Integrated regulator allows 3.3V single power operation. | ||
| ● The integrated MOSFET switch with the short circuit protection allows direct power control for all of Flash Memory card, and that results in a reduction of BOM (bill of material) cost. | ||
| Internal PLL | ||
| ● The optimum frequency for each medias, supplied by an internal PLL, provides a high-performance. | ||
| Small Package | ||
| ● Small 48-pin QFN package provides space saving feature. | ||
| ● The R5U230 is ideal for devices that require miniaturization. | ||
| Applications | ||
| ● Personal computers (laptop, palmtop, note-book, stylus-operated, or tablet PC) | ||
| ● Docking stations | ||
| ● Car navigation systems | ||
| ● PDA | ||
| ● Express Card | ||
| ● Media card readers, etc. | ||
