SDIO101AIHRZ

Controllers Overview

The SDIO101AIHRZ is an SD/SDIO/MMC/CE-ATA host controller manufactured by NXP Semiconductors. It conforms to the SD Host Standard Specification Version 2.0 and supports full-speed (< 25 MHz) and high-speed (< 52 MHz) data transmissions. The device features a 16-bit asynchronous memory interface operating at 2.5 V to 3.3 V, with separate supply pins for the host interface (VDD(IO)), core (VDD), and SD slot (VDD(SD)). It includes a built-in 2 kB double data buffer and supports slave-DMA transfer operations. The component operates within a temperature range of -40 °C to +85 °C and is housed in an HXQFN60 package.

Controllers Feature Summary

• Supports 1-bit, 4-bit, and 8-bit transaction modes for SD, SDIO, MMC, and CE-ATA protocols
• Includes a built-in 2 kB double data buffer to minimize interrupt latency
• Provides five levels of power saving, including Hibernate and Coma modes
• Features an on-board PLL and fractional divider for precise clock speed generation

Controllers Applications

• Microprocessor systems requiring SD/SDIO/MMC/CE-ATA host functionality
• Portable consumer electronics utilizing standard SD card interfaces
• Industrial or embedded applications needing low-power storage controllers

Controllers Procurement Notes

Verify that the ordering suffix 'Z' corresponds to the reel packing method specified in the official documentation. Confirm the package type matches the HXQFN60 description. Ensure the temperature rating aligns with the required operational environment limits defined in the datasheet.

Controllers Selection Notes

Select this component when a 16-bit asynchronous interface is required for the host processor. It is suitable for designs needing independent voltage control for the SD slot and host interface. Consider the available DMA capabilities and power management features if system efficiency is a priority.

Controllers Part Context

This part belongs to the SDIO101A family of host controllers from NXP Semiconductors. It is designed to add standard SD/SDIO/MMC/CE-ATA host functionality to various microprocessor systems through compatible driver software.

Controllers Replacement Considerations

Check for other variants within the SDIO101A family that may offer different packaging options such as trays instead of reels. Verify compatibility with existing board layouts if substituting with non-'Z' suffix versions.
