Product details
Overview
AT25DN011-XMHF-T from Renesas Electronics is a 1-Mbit SPI serial Flash memory IC supporting Dual-Output Read, 104 MHz max clock frequency, 6 ns clock-to-output delay, 2.3–3.6 V single supply, and industrial temperature range operation. It serves as nonvolatile code/data storage in microcontroller boot systems and firmware update modules.
For engineers reviewing the AT25DN011-XMHF-T datasheet, AT25DN011-XMHF-T pinout, AT25DN011-XMHF-T application, or AT25DN011-XMHF-T equivalent, key selection criteria include dual-read throughput, ultra-deep power-down current (350 nA), flexible erase granularity (256-byte page / 4-kB & 32-kB blocks), OTP security register, and hardware write protection via WP pin.
Technical Context
The AT25DN011-XMHF-T implements a standard SPI interface compliant with Modes 0 and 3, using rising-edge data latching on SI and falling-edge data output on SO. Its Dual-Output Read mode repurposes the SI pin as I/O0 alongside SO (I/O1) to deliver two bits per SCK cycle at up to 50 MHz.
Internally, it features a segmented memory architecture with uniform 4-kB and 32-kB erase blocks plus 256-byte page erase, enabling efficient co-location of code and data without cross-contamination. Protection is enforced via status register bits and hardware-controlled WP pin assertion.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory Density | 1 Mbit (131,072 bytes), sufficient for MCU boot code + configuration data in space-constrained designs. |
| Supply Voltage | 2.3 V – 3.6 V single rail - eliminates need for charge pumps or auxiliary supplies during program/erase. |
| Max Clock Frequency | 104 MHz for standard read/program/erase; 50 MHz for Dual-Output Read - enables high-throughput firmware loading. |
| Access Time | 6 ns clock-to-output (tV) - supports tight timing margins in high-speed host interfaces. |
| Erase Granularity | 256-byte page, 4-kB block, 32-kB block, full chip - allows precise updates without erasing unrelated firmware sections. |
| Power-Down Current | 350 nA ultra-deep power-down (typical) - extends battery life in always-on IoT edge nodes. |
| Endurance & Retention | 100,000 program/erase cycles; 20-year data retention - meets long-life requirements for industrial firmware storage. |
Pinout & Package
AT25DN011-XMHF-T is packaged in an 8-lead SOIC (150-mil) with standard JEDEC footprint and pinout.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| CS | Chip Select input | Active-low enable; must transition high→low to initiate command, low→high to terminate - ensures deterministic SPI transaction framing. |
| SCK | Serial clock input | Drives all internal timing; data latched on rising edge, output shifted on falling edge - defines synchronous SPI timing alignment. |
| SI (I/O0) | Serial input / Dual-Read output | Primary command/address/data input; becomes bidirectional I/O0 during Dual-Output Read - doubles read bandwidth without extra pins. |
| SO (I/O1) | Serial output / Dual-Read output | Standard read data output; remains active I/O1 during Dual-Output Read - pairs with SI to deliver 2-bit parallel output per clock. |
| WP | Hardware write protect input | Low-active pin that locks protected sectors regardless of software commands - provides fail-safe firmware integrity. |
| HOLD | Communication pause input | Halts ongoing SPI transfer without deselecting device or resetting state - preserves context during host interrupt servicing. |
| VCC | Power supply | 2.3–3.6 V primary supply; powers all logic and memory array - no separate VPP required for programming. |
| GND | Ground reference | System ground return path for all internal circuits - must be low-impedance to maintain signal integrity and noise immunity. |
Key Features
| Feature | Design Value |
|---|---|
| Dual-Output Read Mode | Enables 2-bit-per-cycle data transfer using SI+SO pins, doubling effective read bandwidth over standard SPI at up to 50 MHz. |
| Flexible Erase Architecture | Supports 256-byte page, 4-kB block, 32-kB block, and full-chip erase - minimizes wasted space when updating mixed code/data segments. |
| 128-byte OTP Security Register | One-time programmable area for device serialization, ESN storage, or cryptographic key binding - prevents cloning and enables secure boot verification. |
| Ultra-Deep Power-Down | 350 nA typical quiescent current with instant wake-up - ideal for battery-powered sensors requiring multi-year shelf life. |
| Hardware Write Protection | WP pin asserts physical lock on protected memory regions independent of status register settings - adds tamper-resistant layer to firmware security. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar serial Flash memory applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Winbond W25Q10EW | Same density (1 Mbit), 1.65–3.6 V supply, 133 MHz max clock, but lacks Dual-Output Read and OTP register. | Higher speed read but no hardware-accelerated dual-I/O mode or embedded security features. | Select when maximum read bandwidth is critical and security features are handled externally. |
| Micron MT25QL01GBBB8E12-0SIT | 1 Gbit density, 1.7–2.0 V core, quad-SPI interface, 133 MHz, includes QE bit and SFDP support - not pin-compatible. | Targeted at higher-density, quad-interface systems; requires PCB redesign and driver adaptation. | Select only when migrating to quad-SPI architecture and scaling memory capacity beyond 1 Mbit. |
Compared with W25Q10EW and MT25QL01GBBB8E12-0SIT, the AT25DN011-XMHF-T uniquely balances low-voltage operation (2.3 V min), dual-output throughput, integrated OTP security, and industrial-grade reliability - making it optimal for cost-sensitive, security-aware, and battery-constrained embedded designs where pin count and power budget are constrained.

FAQ
What is the minimum operating voltage for the AT25DN011-XMHF-T?
The AT25DN011-XMHF-T operates down to 2.3 V across the full industrial temperature range (−40°C to +85°C). This low minimum voltage enables compatibility with modern low-power MCUs and battery-powered systems without requiring level-shifting or voltage boosting circuitry. The AT25DN011-XMHF-T maintains full functionality-including program, erase, and Dual-Output Read-at 2.3 V, as verified in the DC characteristics table of the official datasheet.
Does the AT25DN011-XMHF-T support Quad-SPI mode?
No, the AT25DN011-XMHF-T does not support Quad-SPI. It supports standard SPI Modes 0 and 3, plus Dual-Output Read using SI and SO as concurrent data outputs. Quad-SPI requires four I/O lines and dedicated opcodes not implemented in the AT25DN011-XMHF-T command set. For quad-interface alternatives, consider Renesas' AT25SF series or other vendor offerings explicitly specifying QSPI support.
How is the 128-byte OTP security register used in the AT25DN011-XMHF-T?
The 128-byte OTP security register in the AT25DN011-XMHF-T is programmed once using the 9Bh opcode and is permanently locked thereafter. It is commonly used for device-specific serialization, storing electronic serial numbers (ESNs), or binding cryptographic keys for secure boot verification. Once written, its contents cannot be altered or erased - ensuring immutable identity or credential storage. The AT25DN011-XMHF-T provides dedicated read (77h) and program (9Bh) commands for this register.
What is the purpose of the HOLD pin on the AT25DN011-XMHF-T?
The HOLD pin on the AT25DN011-XMHF-T temporarily suspends SPI communication without deselecting the device or resetting internal state. When asserted (low), it places SO in high-impedance and ignores SCK and SI transitions, preserving the current command context. This allows the host MCU to service interrupts or perform other tasks mid-transfer and resume seamlessly - critical for real-time systems where deterministic latency matters. The AT25DN011-XMHF-T requires CS to remain asserted and SCK low to enter HOLD.
Can the AT25DN011-XMHF-T be used in automotive applications?
The AT25DN011-XMHF-T is specified for the full industrial temperature range (−40°C to +85°C) and complies with RoHS and green packaging standards, but it is not qualified to AEC-Q100. While it may function in some under-hood or infotainment applications, Renesas does not guarantee automotive-grade reliability, failure-in-time (FIT) rates, or stress-test compliance for this part. For automotive use, select AEC-Q100 qualified variants such as the AT25DF041A-AU or equivalent automotive-qualified serial Flash devices.
