SDIO 2.0 Controller ASSP
The Arasan AC2200ie SDIO Controller is an ASSP with an SDIO interface that communicates with devices connected to APB, Parallel, and UART buses. The controller is designed to support a wide range of portable low-power applications such as GPS, UWB, camera, Zigbee, RFID, scanner, etc.
The availability of APB, Parallel, and UART interfaces provides flexibility for implementation of applications that require the conversion of data to feed the SD bus. The AC2200ie SDIO Controller can be configured to operate as a master when the application logic does not have a CPU. The AC2200ie can initiate and control data transfers to application logic. In applications with embedded processors such as ARM or 8051, the AC2200ie can be configured to provide a slave interface. In slave mode, the application CPU controls the initialization of AC2200ie and the setting of its internal registers.
An optional EEPROM can be used with the AC2200ie. The EEPROM can either be programmed by the SD host or CPU connected to the AC2200ie, or be used for initializing devices attached to the AC2200ie. The AC2200ie SDIO Controller ASSP is implemented in 0.25-micron, 3.3 V technology. It is available in 64 TFBGA package with industrial operating temperature. The device is RoHS compliant and is qualified for both industrial and commercial grades. The AC2200ie SDIO Controller is pin compatible with the AC21C00 SDIO Controller. The AC2200ie replaces the AC21C00.
