Product details
Overview
AT25DN011-MAHF-T 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 2.3 V to 3.6 V, supports SPI Modes 0/3 and Dual-Output Read, delivers 104 MHz max clock frequency, and achieves 6 ns clock-to-output timing - enabling fast boot and firmware update in industrial controllers and IoT edge nodes.
For engineers reviewing the AT25DN011-MAHF-T datasheet, AT25DN011-MAHF-T pinout, AT25DN011-MAHF-T application, or AT25DN011-MAHF-T equivalent, key selection criteria include dual-output read throughput, ultra-deep power-down current (350 nA), flexible erase granularity (256-byte page / 4-kB & 32-kB blocks), OTP security register, and industrial temperature support (–40°C to +85°C).
Technical Context
The AT25DN011-MAHF-T implements a dedicated SPI interface with hardware-controlled write protection via WP pin and suspend/resume capability via HOLD pin. Its command set includes standardized opcodes (e.g., 03h/0Bh for standard/dual-read, 02h for page program, 20h/52h for 4-kB/32-kB block erase) compliant with JEDEC ID reading (9Fh) and legacy compatibility (15h).
Internally, it features a segmented memory architecture with uniform 4-kB and 32-kB erase blocks plus 256-byte programmable pages, enabling efficient co-location of code modules and data segments without cross-contamination. The integrated 128-byte OTP security register supports device serialization and ESN storage independent of main array operations.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory Density | 1 Mbit (128 KBytes) - sufficient for bootloader, firmware image, and configuration data in compact MCU-based designs. |
| Supply Voltage | 2.3 V – 3.6 V - enables direct interfacing with 2.5 V and 3.3 V logic domains without level-shifting. |
| Max Clock Frequency | 104 MHz - supports high-speed read access for real-time code execution and rapid firmware updates. |
| Read Latency | 6 ns clock-to-output (tV) - minimizes wait states during instruction fetch and improves system responsiveness. |

Pinout & Package
AT25DN011-MAHF-T is packaged in an 8-lead SOIC (150-mil) with industry-standard pinout compatible with JEDEC MS-012. All pins are electrically validated per datasheet Rev. K.
| 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 | Input clock controlling data latching (rising edge) and output timing (falling edge); supports up to 104 MHz. |
| SI (I/O0) | Serial Input / Dual-Read Output | Primary command/address/data input; becomes I/O0 output during Dual-Output Read (3Bh) for concurrent 2-bit transfer. |
| SO (I/O1) | Serial Output / Dual-Read Output | Standard data output; remains active as I/O1 during Dual-Output Read to deliver second bit per SCK cycle. |
| WP | Write Protect | Hardware lock control for protected sectors; low-active; internally pulled high; optional external tie to VCC. |
| HOLD | Communication Suspend | Pauses ongoing SPI transfers without deselecting device or resetting internal state; low-active; internally pulled high. |
| VCC | Power Supply | Single 2.3–3.6 V supply; powers all internal logic and memory array; no auxiliary voltage required. |
| GND | Ground Reference | System ground return path; must be low-impedance connection for stable read/write margins and noise immunity. |
Key Features
| Feature | Design Value |
|---|---|
| Dual-Output Read (3Bh) | Enables 2-bit-per-clock-cycle data transfer using SI+SO outputs, doubling effective read bandwidth over standard SPI Read (0Bh) at same clock rate. |
| Flexible Erase Architecture | Supports 256-byte page, 4-kB block, 32-kB block, and full-chip erase - eliminates need for external EEPROM or FRAM in mixed code+data applications. |
| 128-byte OTP Security Register | One-time programmable space for immutable device identifiers, cryptographic keys, or calibration data - isolated from main array and immune to accidental overwrite. |
| Ultra-Deep Power-Down Mode | Reduces current to 350 nA typical while preserving memory contents - ideal for battery-backed systems requiring multi-year shelf life or infrequent wake-up. |
| Hardware Write Protection | WP pin provides physical sector locking independent of software status register settings - prevents corruption during brown-out or firmware faults. |

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 | 1-Mbit density, 1.65–3.6 V supply, 133 MHz max clock, no dual-output read mode, 1.5 µA deep power-down (vs. 7.5 µA). | Lacks dual-output read; higher speed but less optimized for low-power data logging due to absence of ultra-deep power-down (350 nA). | Select when maximum read throughput is prioritized over ultra-low standby current and dual-read capability is unnecessary. |
| Micron MT25QL01GBBB8E12-0SIT | 1-Gbit density (1000× larger), quad-SPI interface, 133 MHz, 2.7–3.6 V only, no 2.3 V support, no OTP register. | Not drop-in compatible due to density, voltage range, and interface differences; requires PCB redesign and firmware adaptation. | Choose only for future-proofing high-capacity needs; not suitable as direct replacement for AT25DN011-MAHF-T in existing 1-Mbit designs. |
Compared with W25Q10EW and MT25QL01GBBB8E12-0SIT, the AT25DN011-MAHF-T uniquely balances ultra-low power (350 nA), dual-output read acceleration, 2.3 V minimum operation, and integrated OTP security - making it optimal for compact, battery-sensitive, and security-aware embedded systems where density and quad-SPI are secondary.

FAQ
What is the maximum SPI clock frequency supported by the AT25DN011-MAHF-T?
The AT25DN011-MAHF-T supports a maximum SPI clock frequency of 104 MHz for most commands including Read Array (0Bh), Dual-Output Read (3Bh), Page Erase (81h), and Block Erase (20h/52h). This enables high-throughput data access and rapid firmware updates in time-critical embedded applications.
Does the AT25DN011-MAHF-T support dual-output read mode, and how does it improve performance?
Yes, the AT25DN011-MAHF-T supports Dual-Output Read using opcode 3Bh, where both SI and SO pins act as outputs to transfer two bits per SCK cycle. This doubles effective read bandwidth compared to standard single-output read (0Bh), reducing firmware load time and improving system responsiveness without increasing clock frequency.
What erase options are available on the AT25DN011-MAHF-T, and why does granularity matter?
The AT25DN011-MAHF-T offers four erase options: 256-byte page, 4-kB block, 32-kB block, and full chip. Granular erase prevents unnecessary wear on unrelated memory regions - for example, updating a 128-byte configuration parameter via page erase avoids erasing adjacent firmware code stored in the same 4-kB block.
How does the 128-byte OTP security register in the AT25DN011-MAHF-T enhance system security?
The 128-byte OTP security register in the AT25DN011-MAHF-T provides one-time programmable space for immutable data such as device serial numbers, cryptographic keys, or calibration constants. Once written, contents cannot be altered - preventing tampering during manufacturing, field deployment, or service, and ensuring trusted identity in secure boot chains.
What is the ultra-deep power-down current of the AT25DN011-MAHF-T, and in which applications is it critical?
The AT25DN011-MAHF-T draws only 350 nA (typical) in ultra-deep power-down mode, making it critical for battery-powered applications with multi-year operational life or infrequent wake-up cycles - such as wireless sensor nodes, smart meters, and medical wearables where every nanoamp impacts total system runtime.
