R5C843 Description

Short technical summary and product information.

The Ricoh R5C843 is a single-chip solution designed to provide a comprehensive set of interfaces for PC Card functionality. It integrates a CardBus bridge, SDIO/SD Host Controller, MMC plus controller, Memory Stick PRO interface, xD-Picture Card controller, and an S400 IEEE 1394a OHCI controller.

This chip connects via a Conventional PCI Bus. Its multiple functions make it suitable for systems requiring diverse media card and high-speed data transfer capabilities. The device supports various memory card formats, enhancing its utility in portable and embedded systems.

Driver support has been noted for PC Card (32-bit CardBus) and FireWire (IEEE 1394a) functionalities, with successful testing reported in Linux distributions. SD Card reader functionality is also reported to work out-of-the-box with specific kernel versions. Memory Stick support relies on specific drivers, and xD-Picture Card functionality is noted as Windows-only.

Potential issues with microSD-to-SD adapters have been documented, which can lead to recognition problems. This is often due to electrical connection quality, with a simple fix of slightly adjusting the adapter or using a better quality adapter.
