| R5U880 Series |
USB2.0-Flash Memory Card Controller LSI R5U880 |
The R5U880 is an USB2.0-Card controller that integrates USB2.0 Transceiver, SIE, CPU, FET Switch and Flash Memory Card access into a single chip. |
| Feature |
| ● Small Package |
| Small 48-pin QFN package provides space saving feature.. |
| The R5U880 is ideal for devices that require miniaturization. |
| ● Low Power Consumption |
| Ricoh’s proprietary APS (Auto Power Save) enables the reduction of power consumption. |
| Ricoh’s driver for USB selective suspend has an additional advantage of being able to reduce power consumption when Ricoh’s driver is used. |
| ● 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 Flash Memory card which reduces BOM (bill of material) cost. |
| ● Internal PLL |
| The optimum frequency for each medias, supplied by an internal PLL, provides a high-performance. |
| 2 or 48 Mhz crystal oscillator is users selectable. |
| Using the external source clock, without the use of crystal oscillator, allows the reductions of BOM (Bills Of Materials) costs. |
| Applications |
| ● Personal computers (laptop, palmtop, stylus-operated, or tablet PC) |
| ● Docking stations |
| ● Car navigation systems |
| ● PDA |
| ● Media card readers, etc. |
