Product details
Overview
AT25DF011-MAHN-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 features 6 ns clock-to-output timing - enabling fast boot and firmware update in portable medical devices and industrial controllers.
For engineers reviewing the AT25DF011-MAHN-T datasheet, AT25DF011-MAHN-T pinout, AT25DF011-MAHN-T application, or AT25DF011-MAHN-T equivalent, key selection criteria include its 256-byte page erase granularity, 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 8-lead SOIC package.
Technical Context
The AT25DF011-MAHN-T implements a flexible three-tier erase architecture (256-byte page, 4-kByte block, 32-kByte block) optimized for mixed code-and-data storage, minimizing wasted space in firmware partitions. Its Dual-Output Read mode uses both SI and SO pins as outputs to deliver two bits per SCK falling edge, doubling throughput over standard Read Array (03h) at up to 50 MHz.
Command execution is fully SPI master–driven with no internal voltage pump; all program/erase operations use the same 1.65–3.6 V supply. Protection is enforced via hardware (WP pin) and software (Status Register bits), while the 128-byte OTP register includes 64 bytes factory-programmed with a unique identifier and 64 bytes user-programmable for secure key storage.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory Density | 1 Mbit (131,072 bytes) - sufficient for bootloader + configuration + small firmware images in space-limited designs. |
| Supply Voltage | 1.65 V to 3.6 V - enables direct interface with 1.8 V and 3.3 V microcontrollers without level-shifting. |
| Max Clock Frequency | 104 MHz - supports high-speed read and command execution, reducing boot time in real-time systems. |
| Read Latency | 6 ns clock-to-output (tV) - ensures minimal delay between address latch and valid data on SO/SI during Dual-Output Read. |
| Erase Granularity | 256-byte page / 4-kByte block / 32-kByte block - allows precise firmware patching and data logging without disturbing adjacent code sections. |
| Power-Down Current | 200 nA ultra-deep power-down (typical) - extends battery life in always-on IoT sensors and wearable health monitors. |
| Endurance & Retention | 100,000 P/E cycles at -40 °C to +85 °C; 20-year data retention - meets industrial lifecycle requirements for field-deployed equipment. |
Pinout & Package
AT25DF011-MAHN-T is supplied in an industry-standard 8-lead SOIC (150-mil) package with gull-wing leads, compatible with automated PCB assembly and reflow soldering.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| CS | Chip Select | Active-low enable signal; must transition low-to-high to complete commands and enter standby mode after self-timed operations. |
| SCK | Serial Clock | Master-generated clock; rising edge latches input (SI), falling edge clocks output (SO/SI in Dual-Output mode). |
| SI (I/O0) | Serial Input / Dual-Output Data 0 | Input for commands/addresses/data; becomes output (I/O0) during Dual-Output Read (3Bh) to deliver LSB-aligned data stream. |
| SO (I/O1) | Serial Output / Dual-Output Data 1 | Primary output for standard reads; remains active (I/O1) in Dual-Output Read to deliver MSB-aligned data stream alongside SI. |
| WP | Write Protect | Hardware lock control; low state enables status register write and sector protection - critical for preventing accidental firmware corruption. |
| HOLD | Communication Pause | Active-low pause signal; suspends SPI transfer without deselecting device or interrupting ongoing erase/program cycles. |
| VCC | Power Supply | Single 1.65–3.6 V rail powers logic, memory array, and I/O - eliminates need for charge pumps or auxiliary supplies. |
| GND | Ground Reference | Common return path for all internal circuitry and I/O signals; must be low-impedance to maintain timing integrity. |
Key Features
| Feature | Design Value |
|---|---|
| Dual-Output Read (3Bh) | Delivers 2-bit parallel data per SCK cycle at up to 50 MHz - doubles effective read bandwidth vs. standard 03h Read Array. |
| Flexible Erase Architecture | 256-byte page erase enables fine-grained firmware updates; 4-kByte and 32-kByte blocks optimize large-section reprogramming without full-chip erase overhead. |
| OTP Security Register | 128-byte one-time programmable area with 64-byte factory-unique ID - supports device authentication and secure key binding in regulated medical systems. |
| Hardware Write Protection | WP pin directly controls Status Register write-enable and sector lock bits - provides fail-safe protection against unintended writes during brown-out or noise events. |
| Ultra-Deep Power-Down | 200 nA typical current draw with full memory retention - ideal for battery-powered applications requiring multi-year shelf life or infrequent wake-up intervals. |

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, Quad SPI support, 104 MHz clock, but no Dual-Output Read; requires QSPI interface for full speed. | Higher capacity for larger firmware; lacks dedicated Dual-Output Read mode - lower throughput in legacy SPI-only hosts. | Select when >1 Mbit storage is needed and host supports Quad SPI; avoid if design relies on AT25DF011-MAHN-T's Dual-Output Read timing. |
| Macronix MX25L1006EM1I-12G | 1-Mbit density, SPI Mode 0/3, 85 MHz max clock, 8 ns tV, no OTP register or ultra-deep power-down (5 µA deep PD only). | Lower cost alternative with similar footprint; missing factory-unique ID and 200 nA power-down - unsuitable for battery-critical or secure serialization use cases. | Select for cost-sensitive industrial controls where OTP and ultra-low power are not required; verify timing margins with 8 ns tV. |
Compared with W25Q80DVSSIG and MX25L1006EM1I-12G, the AT25DF011-MAHN-T uniquely combines 256-byte page erase, Dual-Output Read, factory-programmed unique ID, and 200 nA ultra-deep power-down - making it optimal for compact, secure, and battery-constrained embedded systems requiring precise firmware management.

FAQ
What is the maximum operating frequency of the AT25DF011-MAHN-T?
The AT25DF011-MAHN-T supports a maximum clock frequency of 104 MHz for most commands including Page Erase, Block Erase, and Chip Erase. For standard Read Array (03h), the limit is 33 MHz; Dual-Output Read (3Bh) operates up to 50 MHz. These values are specified across the -40 °C to +85 °C temperature range and 1.65–3.6 V supply.
Does the AT25DF011-MAHN-T support hardware write protection?
Yes, the AT25DF011-MAHN-T includes hardware write protection controlled by the WP (Write Protect) pin. When WP is driven low, it enables hardware locking of protected sectors and restricts writes to the Status Register. The WP pin is internally pulled high, so it can be left floating if unused - though external connection to VCC is recommended for noise immunity.
What package type is used for the AT25DF011-MAHN-T?
The AT25DF011-MAHN-T is packaged in an 8-lead SOIC (150-mil) body with gull-wing leads. This package is JEDEC-compliant, RoHS-compliant, and compatible with standard surface-mount assembly processes. Pinout matches industry-standard SPI Flash footprints, simplifying board layout and second-source qualification.
How does the Dual-Output Read feature work on the AT25DF011-MAHN-T?
The AT25DF011-MAHN-T's Dual-Output Read (3Bh command) uses both the SI (I/O0) and SO (I/O1) pins as simultaneous outputs, delivering two bits per SCK falling edge. This doubles data throughput versus standard Read Array (03h). SI transitions from input to output only during this command; all other operations retain conventional SPI I/O roles.
What is the purpose of the OTP Security Register in the AT25DF011-MAHN-T?
The 128-byte OTP Security Register in the AT25DF011-MAHN-T contains 64 bytes factory-programmed with a unique device identifier and 64 bytes user-programmable for secure keys or calibration data. Once programmed, OTP bytes cannot be erased or rewritten - providing tamper-resistant storage for electronic serial numbers, cryptographic keys, or regulatory compliance identifiers.
