Host I/F SD/MMC/SDIO Bridge

Part No.	W86L488Y/AY
Datasheet	W86L488.pdf
Description	The W86L488 is a SD/SDIO/MMC interface bridge between microprocessor and SD/SDIO/MMC applications. The data width of microprocessor should be 16-bits. W86L488 supports synchronous or asynchronous type of host interface. It also supports interrupt or DMA mode to improve data transfer performance. By W86L488 internal register controlled and monitored, you can easily trace the signal between microprocessor and application I/F. W86L488Y/AY can meet the most of IA devices requirement, such as PDA, Cellular Phone, DSC, and MP3 player applications and reserve the flexibility of your design.
Features	Compliant with SD and SDIO spec. Version 1.01. Compliant with MMC spec. Version 3.X. Simultaneously access two ports of SD/SDIO/MMC supported. (W86L488AY only) Support SD/MMC and SPI mode for SD/SDIO/MMC interface. Support SDIO interrupt and bus suspend/resume operation. Support two types of Host microprocessor Interface access – synchronous and asynchronous. DMA and Interrupt transfer mode supported. Extra 5 programmable GPIO supported, 12 programmable GPIO (W86L488AY only) Support 16 bits data bus of Microprocessor I/F
