SDXC Host Controller
iW-SDXC Host controller is compatible with the SD Physical Layer specification V3.0. The core supports 32 bit AHB LITE Host interface working at SOC interface frequency. The Host interface is compatible with the standard register set for the host controller as per SD host controller specification Version 3.0.
Features
- Compliant with SD specification version 3.0
- Supports 32 bit AHB LITE synchronous Host interface working at SOC interface frequency.
- 1-bit/4-bit modes of SD/SDIO supported.
- Supports following UHS –I modes of operations.
- DS – Default speed mode up to 25MHz 3.3V signaling
- HS – High Speed mode up to 50MHz 3.3V signaling
- SDR12 – SDR up to 25MHz 1.8V signaling
- SDR25 – SDR up to 50MHz 1.8V signaling
- SDR50 – SDR up to 100MHz 1.8V signaling
- DDR50 – DDR up to 50MHz 1.8V signaling
- One data Transmit FIFO with 32-bit write width and 256 depths.
- One data Receive FIFO with 32-bit read width and 256 depths.
- SDIO Interrupts, Suspend/Resume Operation and SDIO Read Wait Operation are supported.
- Buffers to store the response received.
- Command buffers to store command index and argument.
Benefits
