R5U242A Specifications

The R5U242A is a multi-function PCI Express controller that integrates 5 PCI Express functions (1-lane PCI Express to a PC Card, an IEEE1394, 1-slot SD/MMC, a Memory Stick and an xD Picture Card) and a built-in Express Card (USB Interface type) switch into a single chip.
The R5U242A supports most Flash Memory Cards currently in the market, and the R5U242A allows flexibility for system designers to configure systems to interface with multiple Flash Memory Cards. The R5U231 offers the low power consumption at the low power state.

Low Power Consumption

  • *Supporting ASPM function and CLKREQ# enables the reduction of the power consumption.

Internal Regulator & Power-Switch

  • *Integrated regulator allows 3.3V single power operation.
  • *The integrated MOSFET switch with the short circuit protection (only Combo Slot support) 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 Easy Layout

  • *Small 144-pin CSP package provides space saving feature.
  • *0.65mm pitch CSP package provides mounting by conventional technology.
  • *The R5U242A 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.
