Overview
Description
The SD card drivers for the RX Family comply with the SD Simplified Specification and consist of a driver which supports SD mode and a driver which supports SPI mode, with both allowing you to control the SD memory and secure digital input/output (SDIO).
You can update or read data by simply calling user API functions. This device driver is a Firmware Integration Technology（FIT） module which supports FIT. In combination with other FIT modules, you can easily include various sample code in user applications. DMAC or DTC transfer can be included by combining the SD card driver with the DMAC FIT module or DTC FIT module.
Features
- SD standard
Complies with the SD Simplified Specification. - Bus Interface
Supports 4-bit SD mode and 1-bit SPI mode. - Numbers controllable
1 card/channel - Speed mode
Supports default speed mode. - Transfer of data in the MCU
You can choose transfer by software, DMA, or the DTC. - MCU-dependent part
Divided out in the SDHI FIT module. - Memory Capacity
Supports standard-capacity SD memory cards (SDSC) and high-capacity and extended-capacity SD memory cards (SDHC and SDXC). - Target for memory control
Support is only for user areas.
We do not support the control of protected areas. - Learn More
