SD memory card driver for SH-2A [R0M726xDS0000RRC]

SD Memory Card Driver for SH-2A

 

This device driver controls an SD memory card through an SD host interface (SDHI) which is embedded in a microcontroller. The driver consists of a group of library functions for access to SD memory cards. In combination with software to handle the file system, data on a card can be updated or read out by calling the API functions of the driver.

Feature

  • Compact software configuration based on the combination with file system.
  • It supports to the SD memory card from 4MB to 2TB.
  • The software transfer or the DMA transfer can be selected as the data transfer method.
  • The CPU dependence part is separated as the target CPU interface function.
  • High-Speed card support.
  • High-Capacity card support.
  • eXtended-Capacity card suppor.
  • Memory-saving configuration.


You will require a license if you intend to develop a system with SD cards. Please contact the SD Association to obtain the license.
