BANGALORE, India -- iW-SD Controller interfaces SD / MMC / SDIO card to any processor with a generic interface. The interface towards the SD card is realized by the SD protocol implemented in the controller.
Highlights
· Compliant with SDIO specification version 2.0, SD specification version 2.0, MMC specification version 4.41
· Controller provides simple slave interface for control & status access and master interface for DMA data transfer
Benefits
· To enable memory storage (SD/MMC memory card) and Input/output (SDIO card) features in the product
· Host controller for SD/SDIO cards where the processor in the platform doesn’t support SD/SDIO interface
· To increase the number of SD/SDIO interface support in the platform
Features
· Compliant with SD Host Controller Standard Specification Version 2.0
· Compliant with SD Physical Layer Specification Version 2.0
· Compliant with SDIO Specification 2.0
· Compliant with eMMC Specification Version 4.41
· Supports 1-bit,4-bit SD/eMMC modes and 8-bit eMMC modes.
· Supports SD Card Detection input pin
· Supports SD Card Write Protection input pin
· Supports programmable clock frequency generation to the SD/eMMC card.
· Supports Interrupt and ADMA2 transfer mode of operation.
· Individual 2Kbyte data buffer for read and write.
· Cyclic Redundancy Check (CRC) for command and data.
· Supports timeout monitoring for response, data, CRC token & busy.
· Supports a maximum block length of 2K-byte.
· Supports both single block and multi block data transfer.
· Supports power ON/OFF control to SD/eMMC card.
