A3P600 Datasheet, PDF (1/1 Pages) Actel Corporation – SD Controller

Overview
iW-SD Controller is an interface between any 8-bit processor and the SD/ MMC/ SDIO card. The interface towards the SD card is
realized by the SD protocol implemented in the controller. The main blocks in the controller are CPU interface, command path
state machine, command transmitter/ receiver, data path state machine, data transmit/receive and clock logic.
Features
 1-bit/4-bit modes of SD, MMC and SDIO supported
 8-bit Generic CPU interface
 Both DMA and Interrupt mode is supported for Data transfer
 Command buffers to store command index and argument
 Any byte size transfers supported. Sector size can be set from 1 byte to 2048 bytes
 CRC generation / checking supported for both command and data transactions
 Compliant with SDIO specification version 1.1
 Compliant with SD specification version 1.1
 Compliant with MMC specification version 2.0
 Using the SD/SDIO/MMC communication protocol, one SDIO or SD or MMC card is supported
 Card Detection / Removal support
 Write protect using mechanical switch
 Interrupts for errors
