NXP Semiconductors SDIO101 SD / SDIO / MMC / CE-ATA Host Controller
The NXP Semiconductors SDIO101 SD / SDIO / MMC /CE-ATA host controller features a standard 16-bit asynchronous memory interface. The NXP Semiconductors SDIO101 manages the physical layer of SD, SDIO, MMC, and CE-ATA protocols and can be used together with SD Host Standard compatible driver software to add SD / SDIO / MMC / CE-ATA host functionality to a variety of microprocessor systems. This NXP Semiconductors host controller supports full-speed (<25 MHz) and high-speed (<52 MHz) data transmissions on the SD / SDIO / MMC /CE-ATA port and offers separate pins for SD / SDIO / MMC / CE-ATA port supply voltage, host interface supply voltage, and core supply voltage. The SDIO101 host controller can operate at a wide voltage range (1.8V to 3.6V), allowing the device to interface to a large variety of SD, SDIO, MMC, or CE-ATA devices.
