Product details
Overview
SDIO101IHR,515 from NXP Semiconductors is a single-slot SD/SDIO/MMC/CE-ATA host controller IC with 16-bit asynchronous memory interface, supporting full-speed (<25 MHz) and high-speed (<52 MHz) data transfers, 1.8 V core supply, and 1.8–3.3 V SD port voltage range. It enables embedded microprocessor systems to interface with SD cards, SDIO peripherals, eMMC, and CE-ATA storage devices in portable, power-constrained applications.
For engineers reviewing the SDIO101IHR,515 datasheet, SDIO101IHR,515 pinout, SDIO101IHR,515 application, or SDIO101IHR,515 equivalent, key selection considerations include its HXQFN60U package, dual-voltage domain support (VDD=1.8 V, VDD(IO)=2.5–3.3 V), built-in 2 kB double-data buffer, fractional clock divider for precise SDCLK tuning, and five-level power management including Hibernate and Coma modes.
Technical Context
The SDIO101IHR,515 implements the SD Host Controller Standard Specification v2.0 register set with four additional proprietary registers for enhanced control. Its architecture integrates a PLL with fractional divider (0xF6), enabling fine-grained SDCLK generation from a single external clock source such as a host processor's 13 MHz crystal - e.g., generating ~48.9 MHz SDCLK via PLL×8 → post-divide → fractional adjustment.
It supports slave-DMA operation via DREQ-driven burst transfers (programmable burst size and inter-delay), interrupt-driven access, and dual-buffered data flow through 2 kB on-chip RAM. Power management includes hardware-controlled Coma mode (internal supply cutoff) and Hibernate mode (oscillator, PLL, and buffer memories disabled), both configurable via the Miscellaneous register (0xF8).
Key Specifications

FAQ
What is the maximum SD clock frequency supported by SDIO101IHR,515?
The SDIO101IHR,515 supports high-speed SD data transmission up to 52 MHz, as defined in SD Host Controller Standard Specification v2.0. Its on-board PLL and fractional divider (0xF6) enable precise derivation of this frequency from common host clocks - for example, generating 48.9 MHz from a 13 MHz crystal input. The SDIO101IHR,515 datasheet confirms full compliance with high-speed timing requirements and specifies 208 Mbit/s throughput using 4-bit SD mode at 52 MHz.
Does SDIO101IHR,515 support eMMC devices?
Yes, SDIO101IHR,515 supports eMMC (embedded MMC) devices through its full MMC Specification v3.31 and v4.2 compliance, including 8-bit data bus operation and CMD60/CMD61 CE-ATA Digital Protocol commands. It handles eMMC boot mode, high-density addressing, and RPMB partition access when paired with compatible driver software. The SDIO101IHR,515 pinout includes dedicated DAT0–DAT7 lines and programmable drive strength for robust signal integrity at 50 MHz.
How does SDIO101IHR,515 manage power for battery-operated devices?
SDIO101IHR,515 offers five programmable power states: Standby, Sleep, Idle, Coma, and Hibernate. In Hibernate mode, the on-board oscillator, PLL, and 2 kB data buffer memories are fully switched off, reducing current draw to microamp levels. Coma mode internally cuts supply to most circuit blocks. Both modes are controlled via the Miscellaneous register (0xF8), enabling firmware-driven ultra-low-power operation essential for portable medical and metering applications using SDIO101IHR,515.
Can SDIO101IHR,515 interface with both 1.8 V and 3.3 V SD cards simultaneously?
No - SDIO101IHR,515 supports either 1.8 V or 3.3 V operation on its SD/SDIO/MMC/CE-ATA port (VDD(SD)), but not both simultaneously. However, its POW[1:0] outputs (B11, A17) and Power Control register (0x29) allow dynamic switching between 1.8 V (low-power) and 3.3 V (normal) supply voltages under software control. This enables single-slot compatibility with diverse cards, provided voltage transitions are sequenced correctly per SD specification - a capability confirmed in SDIO101IHR,515's functional description section 6.3.6.
What host processor interfaces are compatible with SDIO101IHR,515?
SDIO101IHR,515 uses a standard 16-bit asynchronous memory interface with CS, RE, WE, BE[1:0], A[7:1], A8, and D[15:0] signals - directly compatible with ARM9, ARM11, and Cortex-A series processors featuring AMBA AHB/APB bridges or generic parallel bus controllers. Its 2.5–3.3 V VDD(IO) supply and programmable INT pin (push-pull or open-drain) ensure seamless integration with common microprocessor families without level-shifting. The SDIO101IHR,515 datasheet explicitly validates this interface against industry-standard memory-mapped host architectures.
