R5C847 Description

Short technical summary and product information.

The Ricoh R5C847 is a single-chip solution designed to provide multiple interface functions over a PCI bus. It integrates a PC Card bridge, a Media Card Interface supporting SD/SDIO/MMC/MMC plus, MS, MSPro, and xD cards, as well as a FireWire (IEEE 1394a) controller with a speed of 400 Mbit/s.

This chip offers six PCI functions, making it suitable for systems requiring diverse peripheral connectivity. The PC Card controller supports both 32-bit CardBus and 16-bit PCMCIA standards, though 16-bit functionality may require specific testing. The FireWire controller is compatible with OHCI standards and has been tested to work with devices like DV cameras.

The integrated SD Host Controller (SDIO) and MultiMediaCard (MMC) controller are supported by various Linux kernels and modules, indicating good compatibility for these functions. However, Memory Stick and xD Picture Card reader functionality is primarily noted for Windows, with experimental or no support in some Linux kernels for the Ricoh chipset.

This component is found in ThinkPad models such as the T61, T61p, T500, R61, and X61 Tablet, highlighting its use in portable computing devices.
