SD memory cards have gained a large share of the market for flash memory and have established themselves as the de facto standard for solid-state digital storage devices. Products, such as mobile phones and digital cameras, that use these cards for storage must incorporate SD memory card control functions.

Renesas recommends the SH-2A and SH-4A MCUs for high-speed access need, which enables an on-chip SD memory card interface. If the emphasis is on compactness and low-power consumption, a range of general-purpose MCU solutions are also available. Developers building systems to their own specifications can choose the MCU that best meets their exact requirements.

Renesas’ MCUs support FAT file system* middleware and SD memory card control device driver, and thus can be used in healthcare / measuring equipments (with data-logger capabilities), audio recording devices, and digital music players.

* FAT file system is a patent of Microsoft Corporation.
