Product details
Overview
AT25DF011-MAHN-Y from Renesas Electronics is a 1-Mbit SPI serial Flash memory IC designed for code shadowing and embedded data storage in resource-constrained systems. It operates from 1.65 V to 3.6 V, supports SPI Modes 0/3, delivers 104 MHz max clock frequency, achieves 6 ns clock-to-output delay, and features dual-output read for enhanced throughput in microcontroller boot and firmware update applications.
For engineers reviewing the AT25DF011-MAHN-Y datasheet, AT25DF011-MAHN-Y pinout, AT25DF011-MAHN-Y application, or AT25DF011-MAHN-Y equivalent, key selection criteria include its 256-byte page erase granularity, 128-byte OTP security register with factory-programmed unique ID, ultra-deep power-down current (200 nA), and support for hardware write protection via WP pin in industrial temperature range.
Technical Context
The AT25DF011-MAHN-Y implements a flexible three-tier erase architecture-256-byte pages, uniform 4-kByte blocks, and 32-kByte blocks-enabling efficient co-location of code modules and data segments without memory waste. Its SPI interface uses standard four-wire signaling (CS/SCK/SI/SO) with rising-edge input capture and falling-edge output timing.
Dual-output read mode repurposes the SI pin as I/O0 alongside SO (I/O1) to deliver two bits per SCK cycle, doubling effective read bandwidth versus standard single-output mode. The device integrates hardware-controlled sector locking via the active-low WP pin and supports software-based protection through status register configuration.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory Density | 1 Mbit (131,072 bytes) - sufficient for MCU boot code, firmware images, and configuration data in space-limited designs. |
| Supply Voltage | 1.65 V to 3.6 V - enables direct interfacing with 1.8 V and 3.3 V logic domains without level shifters. |
| Max Clock Frequency | 104 MHz - supports high-speed read operations critical for fast boot and real-time firmware loading. |
| Read Latency | 6 ns clock-to-output (tV) - minimizes wait states during instruction fetch from external Flash. |
| Erase Granularity | 256-byte page / 4-kByte block / 32-kByte block - allows precise in-field updates without erasing unrelated code or data. |
| Power-Down Current | 200 nA ultra-deep power-down (typical) - extends battery life in always-on IoT edge nodes and portable devices. |
| Endurance & Retention | 100,000 program/erase cycles at -40°C to +85°C; 20-year data retention - suitable for long-life industrial deployments. |
Pinout & Package
AT25DF011-MAHN-Y is packaged in an 8-lead SOIC (150-mil) with standard JEDEC footprint and pinout.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| CS | Chip Select | Active-low enable signal; must transition low-to-high to terminate self-timed operations like erase or program. |
| SCK | Serial Clock | Master-generated clock; data latched on rising edge, output shifted on falling edge per SPI Mode 0/3. |
| SI (I/O0) | Serial Input / Dual-Output Data 0 | Command/address/data input; becomes output (I/O0) during dual-output read to double data rate. |
| SO (I/O1) | Serial Output / Dual-Output Data 1 | Data output; remains active (I/O1) during dual-output read, paired with SI for concurrent bit transfer. |
| WP | Write Protect | Hardware lock control; low assertion enables status register write and sector protection configuration. |
| HOLD | Communication Pause | Active-low hold signal; suspends SPI transfers without deselecting device or resetting internal state. |
| VCC | Power Supply | Single supply input (1.65–3.6 V); powers all internal logic and memory array-no auxiliary voltage required. |
| GND | Ground Reference | System ground return path; must be low-impedance to ensure stable read/write margins and noise immunity. |
Key Features
| Feature | Design Value |
|---|---|
| Dual-output read mode | Enables 2-bit-per-cycle data transfer using SI and SO pins, increasing effective read bandwidth by 100% over standard SPI read. |
| Flexible erase architecture | Supports 256-byte page, 4-kByte block, and 32-kByte block erase-reducing wasted space and enabling granular firmware updates. |
| 128-byte OTP security register | Contains 64 bytes factory-programmed unique identifier and 64 bytes user-programmable space for ESN, keys, or calibration data. |
| Ultra-deep power-down | Reduces current draw to 200 nA typical, extending battery life in maintenance-free sensor nodes and wearable devices. |
| Hardware write protection | WP pin provides physical lock control for protected sectors, preventing accidental writes during system operation or reset events. |

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 W25Q80DVSSIG | 8-Mbit density, 133 MHz max clock, Quad SPI support, no dual-output read; 100,000-cycle endurance same. | Higher capacity and faster clock but lacks dual-output mode; requires different command set and driver adaptation. | Select when higher density and quad interface are needed; not drop-in due to command and timing differences. |
| Micron MT25QL01GBBB8E12-0SIT | 1-Gbit density, 133 MHz, Octal DTR support, deep power-down current 2 µA (vs. 200 nA), extended temp up to +125°C. | Targeted at automotive under-hood use; higher power consumption in sleep mode reduces battery life in portable designs. | Prefer for high-temp automotive applications; avoid where ultra-low standby current is mandatory. |
Compared with W25Q80DVSSIG and MT25QL01GBBB8E12-0SIT, the AT25DF011-MAHN-Y offers superior ultra-deep power-down efficiency (200 nA), native dual-output read for bandwidth-constrained MCUs, and optimized 256-byte page erase-making it ideal for compact, battery-sensitive embedded systems requiring precise firmware update control.

FAQ
What is the operating voltage range of the AT25DF011-MAHN-Y?
The AT25DF011-MAHN-Y operates from 1.65 V to 3.6 V across its full industrial temperature range (-40°C to +85°C). At the extended temperature range (-40°C to +125°C), the minimum supply voltage increases to 1.7 V. This single-supply design eliminates the need for auxiliary voltage rails and simplifies power architecture in mixed-voltage systems.
Does the AT25DF011-MAHN-Y support dual-output read, and how does it improve performance?
Yes, the AT25DF011-MAHN-Y supports dual-output read using the 3Bh opcode, which repurposes the SI pin as I/O0 alongside SO (I/O1) to output two bits per SCK cycle. This doubles effective read throughput compared to standard single-output mode (03h/0Bh), reducing firmware load time and improving boot speed in microcontroller-based systems without requiring hardware redesign.
How is hardware write protection implemented on the AT25DF011-MAHN-Y?
Hardware write protection on the AT25DF011-MAHN-Y is controlled by the active-low WP pin. When asserted low, it enables hardware locking of protected memory sectors as defined in the status register. The WP pin is internally pulled high, allowing it to be left floating if unused-but Renesas recommends tying it to VCC externally for noise immunity and predictable default behavior during power-up.
What is the purpose and structure of the OTP security register in the AT25DF011-MAHN-Y?
The AT25DF011-MAHN-Y includes a 128-byte One-Time Programmable (OTP) security register: 64 bytes are factory-programmed with a unique device identifier, and 64 bytes are user-programmable for ESN, cryptographic keys, or calibration data. Once written, OTP bytes cannot be erased or rewritten-providing tamper-resistant storage for secure device authentication and traceability.
What erase options does the AT25DF011-MAHN-Y provide, and why is page-level erase important?
The AT25DF011-MAHN-Y supports 256-byte page erase, 4-kByte block erase, 32-kByte block erase, and full chip erase. Page-level erase is critical for in-field firmware updates because it allows modification of small code segments or configuration data without erasing adjacent, functionally unrelated memory-preserving system stability and minimizing update window duration.
