Product details
Overview
AT25DF011-MAHNGU-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 1.65 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 AT25DF011-MAHNGU-T datasheet, AT25DF011-MAHNGU-T pinout, AT25DF011-MAHNGU-T application, or AT25DF011-MAHNGU-T equivalent, key selection criteria include its 256-byte page erase granularity, 128-byte OTP security register with factory-unique ID, ultra-deep power-down current (200 nA), and support for hardware write protection via WP pin in 8-pin SOIC, TSSOP, and UDFN packages.
Technical Context
The AT25DF011-MAHNGU-T implements a flexible erase architecture with three granularities: 256-byte pages, uniform 4-kByte blocks, and uniform 32-kByte blocks - optimized to minimize wasted space in mixed code+data layouts. Its Dual-Output Read mode uses both SI and SO pins as outputs, doubling data throughput versus standard SPI Read Array (03h) at up to 50 MHz.
It integrates hardware-controlled sector locking via the WP pin and software-configurable protection through Status Register bits. The device includes a dedicated 128-byte OTP Security Register - split into 64 bytes factory-programmed with a unique identifier and 64 bytes user-programmable - supporting secure boot and device authentication without external crypto elements.
Key Specifications

Pinout & Package
AT25DF011-MAHNGU-T is packaged in an industry-standard 8-lead SOIC (150-mil) with gull-wing leads, compatible with automated SMT assembly and IPC-7351 footprint standards.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| CS | Chip Select Input | Active-low enable signal; must transition high→low to initiate command, low→high to terminate operation. |
| SCK | Serial Clock Input | Drives all data transfers; rising edge latches input (SI), falling edge clocks output (SO/SI in Dual-Read). |
| SI (I/O0) | Serial Input / Dual-Read Output | Primary command/address/data input; becomes bidirectional I/O0 during Dual-Output Read (3Bh) for parallel bit streaming. |
| SO (I/O1) | Serial Output / Dual-Read Output | Standard data output; remains active I/O1 during Dual-Output Read to deliver second bit per clock cycle. |
| WP | Hardware Write Protect Input | Low-active pin enabling hardware lock of protected sectors; internally pulled high - float or tie to VCC if unused. |
| HOLD | Communication Pause Input | Low-active pin suspends ongoing SPI transfer without deselecting device or resetting internal state. |
| VCC | Power Supply | Single 1.65–3.6 V supply powers core logic and memory array; no auxiliary voltage required for programming/erasing. |
| GND | Ground Reference | System ground return path; must be low-impedance and co-located with VCC decoupling capacitor. |

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 (not Dual-Output), no OTP register. | Better suited for larger firmware images; lacks hardware-secured device identity for secure boot. | Select when higher capacity and quad interface are needed; avoid if OTP-based secure provisioning is required. |
| Macronix MX25L1006EM1I-12G | 1-Mbit density, 80 MHz max clock, standard SPI only (no Dual-Output), 100K-cycle endurance, no OTP register. | Lower performance and no dual-read acceleration; lacks factory-programmed unique ID. | Choose for cost-sensitive, non-security-critical applications where 104 MHz speed and OTP are not required. |
Compared with W25Q80DVSSIG and MX25L1006EM1I-12G, AT25DF011-MAHNGU-T uniquely combines 104 MHz operation, Dual-Output Read, and factory-programmed OTP ID - making it optimal for secure, low-latency, space-constrained embedded boot and data logging.

FAQ
What is the maximum operating frequency supported by the AT25DF011-MAHNGU-T?
The AT25DF011-MAHNGU-T supports a maximum operating frequency of 104 MHz for standard Read Array (0Bh) and Dual-Output Read (3Bh) commands. This enables high-throughput data access in time-critical embedded applications. The device maintains full functionality across its specified voltage range (1.65 V to 3.6 V) and temperature range (-40 °C to +85 °C). AT25DF011-MAHNGU-T achieves this performance without requiring auxiliary voltage rails or external timing components.
Does the AT25DF011-MAHNGU-T support hardware write protection?
Yes, the AT25DF011-MAHNGU-T includes a dedicated WP (Write Protect) pin that enables hardware-controlled locking of protected memory sectors. When asserted low, the WP pin immediately prevents write and erase operations on configured sectors - independent of software status register settings. The pin is internally pulled high, so it may be left floating if hardware protection is not used, though Renesas recommends tying it to VCC for noise immunity. AT25DF011-MAHNGU-T supports both hardware and software protection modes for robust data integrity.
What is the purpose and structure of the OTP Security Register in the AT25DF011-MAHNGU-T?
The AT25DF011-MAHNGU-T includes a 128-byte One-Time Programmable (OTP) Security Register divided into two 64-byte segments: the first is factory-programmed with a unique device identifier, and the second is user-programmable for keys, certificates, or custom identifiers. Once programmed, OTP bits cannot be erased or rewritten - ensuring permanent, tamper-resistant device identity. This feature directly supports secure boot, anti-counterfeiting, and cryptographic key binding in safety-critical systems. AT25DF011-MAHNGU-T implements dedicated Program OTP and Read OTP commands (42h/4Bh) for controlled access.
How does the Dual-Output Read mode improve performance in the AT25DF011-MAHNGU-T?
The AT25DF011-MAHNGU-T's Dual-Output Read mode (command 3Bh) uses both the SI and SO pins as simultaneous data outputs, delivering two bits per clock cycle instead of one - effectively doubling read throughput compared to standard SPI Read Array (03h/0Bh). At its rated 50 MHz Dual-Read clock, this yields ~100 MB/s effective bandwidth. This acceleration is especially valuable for graphics asset loading, firmware decompression, and real-time data streaming in resource-limited MCUs. AT25DF011-MAHNGU-T maintains full compatibility with legacy SPI controllers while enabling this performance boost when supported.
What power-saving modes are available in the AT25DF011-MAHNGU-T, and what are their typical current draws?
The AT25DF011-MAHNGU-T offers three low-power states: Standby (25 µA typical), Deep Power-Down (5 µA typical), and Ultra-Deep Power-Down (200 nA typical). Ultra-Deep mode disables all internal circuitry except the wake-up detection logic, making it ideal for battery-powered endpoints that spend >99% of time asleep. Recovery from Ultra-Deep mode requires a Chip Select toggle or specific command sequence. All modes retain full memory contents. AT25DF011-MAHNGU-T achieves these ultra-low currents without external capacitors or auxiliary control signals.
